2020 Ontario frost laws, seasonal load weight and speed restrictions.
Restrictions on permits during frost or thaw law months.
All annual and project heavy haul trucking permits are not valid on any highways unless otherwise specified on the permit during frost or thaw months:
March and April in Southern Ontario
March, April and May in Northern Ontario
For the purposes of this restriction the Province of Ontario is divided, west to east, by:
A line formed by the Severn River to Regional Rd. 169
Regional Rd. 169 from Washago to Hwy. 12
Hwy. 12, from Regional Rd. 169 to Hwy. 7, north of Sunderland
Hwy. 7, from Hwy. 12 to Regional Rd. 7B at Carleton Place
Regional Rd. 7B to Hwy. 15
Regional Rd. 29 to Arnprior
Single trip permits for transporting heavy haul shipments on highways not designated in Schedules 1, 2 and 3, may be issued but are subject to axle weight controls established by the Ministry of Transportation.
Pursuant to The Highway Traffic Act, the Ontario Ministry of Transportation will impose reduced load weight limits for designated parts of the provincial highways between March 1 and April 30, for Schedule 1 and Schedule 2 roadways, and from March 1 to June 30 for Schedule 3 roadways.
Spring frost/thaw law weight maximums (restrictions) for Ontario:
Reduced loads.

It is important for truck drivers and trucking company dispatchers to make certain they are operating in accordance with the Ontario posted frost laws, seasonal load weight and speed restrictions that are posted. Changes to these restrictions is subject to change hourly during the winter and spring months. You are expected to be aware of these changes and operate accordingly. It is possible that heavy fines may be levied as well as your truck being ordered out of service and not permitted to travel. We suggest you bookmark this page for future reference.
Seasonal weight restrictions limit the maximum weight of vehicles allowed to travel on certain roads as a way to help prevent damage and protect public investment in the roadways.

2020 New Brunswick frost laws, seasonal load weight and speed restrictions.
Spring frost law/thaw law weight restrictions.
Spring weight restrictions for truck traffic will come into effect on Monday, March 11th, in southern New Brunswick and on Monday , March 18th , in northern New Brunswick. Restrictions will continue until midnight on Sunday, May 14th, in southern New Brunswick and midnight, Sunday, May 21th, in northern New Brunswick. These dates are dependent upon weather conditions and are subject to change.
“These weight limits are put in place every spring to ensure that our road infrastructure does not suffer damage during the annual frost and thaw cycle,” said Transportation and Infrastructure Minister Bill Fraser. “We provide this notice to the trucking community so that they may prepare to reduce their loads or plan alternate routes during this period. I thank members of the industry for the co-operation and patience they demonstrate each year while these restrictions are in place.”
For the purpose of these restrictions, northern New Brunswick includes:
The area lying within the counties of Northumberland, Gloucester, Restigouche, Madawaska and Victoria.
The portion of Route 108 within York County.
The portion of Gordon Vale Road and Holtville Road within York County.
The portion of Route 123 within Sunbury County and Queens County.
The portion of Bloomfield Ridge Road between Holtville Road and Route 625.
The portion of Route 625 between Gordon Vale Road and Route 8.
Details are available online. Should weather conditions warrant, district engineers are authorized to close roads to trucks or impose weight restrictions on highways or portions of highways.
How to calculate your truck weights for spring thaw/frost transport.
It is important for truck drivers and trucking company dispatchers to make certain they are operating in accordance with the New Brunswick posted frost laws, seasonal load weight and speed restrictions that are posted. Changes to these restrictions is subject to change hourly during the winter and spring months. You are expected to be aware of these changes and operate accordingly. It is possible that heavy fines may be levied as well as your truck being ordered out of service and not permitted to travel. We suggest you bookmark this page for future reference.
Seasonal weight restrictions limit the maximum weight of vehicles allowed to travel on certain roads as a way to help prevent damage and protect public investment in the roadways.

2020 Alberta frost laws, seasonal load weight and speed restrictions.
Just like any other Province Alberta has seasonal frost laws. However The Alberta Ministry of Transportation offers a e-mail notification service on their website to drivers who wish to stay up-to-date and legal on the latest road ban orders and seasonal weight restrictions. According to the website seasonal weights for heavy haul trucking are set according to the following schedule:
Spring: weather dependent, subject to thaw depth readings and begins at same time as Period 1 (weather dependent, subject to thaw readings of at last 25 cm.
Winter: weather dependent, subject to frost depth readings of one meter or more. In winter, trucking weights can be greater because the pavement is less vulnerable when the ground beneath it is frozen, providing support.
Seasonal Weights
Seasonal weights for heavy haul trucking are set according to the following schedule:
Spring: weather dependent, subject to thaw depth readings of at least 25 centimeters and begins at same time as Period 1 weights for service rigs
Post-Thaw: June 16 (may begin one week earlier or one week later)
Summer: July 1
Fall: September 1
Winter: weather dependent, subject to frost depth readings of 75 centimeters or more.
Seasonal weights for service rigs are set according to the following schedule:
Period 1: weather dependent, subject to thaw depth readings of at least 25 centimeters and begins at same time as Spring weights for heavy haul
Period 2: June 16 (may begin one week earlier or one week later)

2020 frost laws, seasonal load weight and speed restrictions by State/Province (USA and Canada).
Section 1. The United States: Restrictions and guidance on seasonal weight restriction laws.
Many states incorporate temporary special weight limits and restrictions (frost laws) during the spring months of the year. These temporary restrictions are usually referred to as “frost laws” and implemented typically during the month or March and April. In some Northern States and Provinces frost laws can still be in effect in July as it’s much colder in the North. Since these restrictions are implemented on a “as needed” basis it is possible many of the official government websites may not have published this temporary restriction in a convenient place as frost laws are also subject to change at any moment based on the temperature of the roads core. You want to be certain to check with the appropriate department officials to verify the latest changes in the laws.
It is very typical for States and Provinces to not be clear about their exact weight requirements during frost law season. This gives them the opportunity to examine each proposal individually on a case-by-case basis to determine if any damages may occur at the time should the shipment be approved. Information may only be available by contacting the SPECIFIC DEPARTMENT. The axle weight limits and spacings are determined by many factors including road conditions, temperature, moisture content in the soil, etc. Note multiple weight limits can be in effect at the exact same time in different parts of the region due to temperature as well as the actual construction of the road.

Section 2. Canada: Restrictions and guidance on seasonal weight restriction laws.
Many Canadian provinces issue spring frost law weight restrictions in the month of March and current Province websites may not be all inclusive of temporary changes in their laws. It is wise to check with the province’s DOT office (or appropriate department) for the most current and latest frost law information.

There’s a delicate balance between protecting roadways during the spring thaw. In order to keep the trucking industry operating the Northern US states and Canadian provinces rely on engineers and scientific data to determine which dates frost laws will be in effect. With fairly recent advances in science and technology, data is much more reliable. This helps with the implementation of “Frost Laws” or “Seasonal Weight Restrictions” ensuring they are not implemented to early or late. While no State or Province desires to delay the transportation of goods through their territory it is imperative public assets are protected.
In areas that constantly get negative temperatures the amount of damages has forced Northern US States as well as Canadian Provinces to create and enact laws that restrict vehicle weights during spring months (specifically trucking companies), when the roads and bridges are thawing. There are all kinds of things that can go wrong with different types of roads and pavements. For example the State of Michigan has implemented permanent frost laws that go into effect during the months of March through May (and in some cases even June). Some routes require the legal axle weight limits be decreased by as much as 35%. Some States and local governments may also limit heavy-haul vehicle speeds to a maximum of 35 miles per hour during the frost law months regardless of posted limits.
Most major highways are constructed in 3 layers. The top layer you see or the pavement usually averages about 4″ to 6″ in thickness depending on it’s age. This layer of pavement is supported by 2 more layers. One is called the base layer and the other a sub-base layer. Together these three layers are typically at least 36″ in depth with most much more thicker. For instance in Southern Oregon on old US Highway 1 which follows the coast line from Mexico to Canada the road is a much as 16 feet thick as years of pavement has been laid. It should be noted that today’s technology is able to provide us with roads that are flexible due to the engineering of the construction process and the materials used. Excessive weight exerted by overloaded axles (or a weakened supporting base) can cause the pavement to bend or deform. The strength of the road combined with its resistance to bending determines the amount of weight the roadway can handle.
Road building technology has improved significantly during the last decade. The most obvious winter damage is the occurrence of potholes that are the result of moisture in the pavement freezing and weakening the top layer of the road. However, modern road building materials significantly reduce the amount of moister retained in the top layers, reducing the occurrence of pot holes. The base and sub-base however are still subject varying amounts of moisture that is influenced by rain, run-off and general moisture content during the spring months.
Roadways are built to carry normal maximum axle and gross weights based a certain level of residual moisture in the layers of the road bed. During the normal winters in the northern states and Canadian provinces, water in the soil typically freezes down to depths of a meter or more, preventing excess water from escaping. In fact, some areas in Canada allow up to a 25% increase in axle and gross weights because the solidly frozen base layers strengthen the road structure. During the spring thaw, however, axle and gross weights may be reduced by as much as 35%.
What exactly are frost laws?
Frost laws are seasonal restrictions on traffic weight limits and speeds on roadways subject to thaw weakening.
During the spring thaw, the roadbed is softened by trapped moisture beneath the pavement, reducing the supporting strength of the road to less than the original construction strengths. As the excess moisture evaporates or drains away, the road bed will stabilize and return to normal design strengths.
Because of the variability of temperatures each year States and Provinces must manage maximum weight and speed restrictions on a seasonal basis to both protect and preserve roads and ensure maximum access to trucking interests.
“Seasonal weight restrictions” typically start in early March and continue through mid-June. Since conditions vary from year to year, from below-normal to above-normal temperatures, most states and provinces reserve the authority to adjust spring load restrictions based on observed seasonal rain and temperature conditions, weather forecasts, as well as soil moisture sampling, to determine the dates for setting and removing weight restrictions. Weight restrictions remain in effect until sufficient moisture has escaped and the roadbeds regain stability. The most significant pavement damage occurs during the first four weeks after the onset of spring thaw.
Some states plan seasonal weight restrictions. For example, Pennsylvania schedules restrictions from February 15th to April 15th based on years of weather data. However, they reserve the authority to post additional restrictions due to unforeseen severe weather conditions.
The State of North Dakota has taken a much more different approach. They utilize temperature probes in the base layer sections, long range temperature forecasts, and sensors in the pavement to evaluate the strength of roadway bases to forecast when load restrictions should be imposed or removed.
A review of transportation departments indicates 16 states have implemented frost laws or seasonal load restrictions. In many states, seasonal weight restrictions are managed by local governments or jurisdictions. Most Canadian provinces also have established spring thaw speed and weight laws.
Note: The strength of a roadway is affected by moisture in the base materials supporting the roadway. The condition of road surface—moisture or frost on the roadway—does not affect roadway strength.
In general, during the spring thaw, maximum axle weights and gross vehicle weights will be reduced as much as 35%. Each state or province has established maximum axle and gross vehicle weights for key national and state trucking routes.
Because these spring load restrictions will vary so widely by state, and even within a state and because seasonal restrictions may be posted on short notice, it is best to check each state’s freeze/thaw laws prior to each trip. Links to seasonal restriction information for each US state or Canadian province are posted above.
Frost laws are created for the States and Providences in the USA and Canada that experience very low temperatures in the winter months frost laws may be enacted. These frost laws have been created to protect the State of Providences from highway and road damage caused by the surface cracking which is a direct result of too much weight being placed on the pavement which causes stress cracks thus damaging it. Also, when the freezing temperatures start to thaw out at times the water can not escape quickly which will cause the water to build up which can weaken the base structure of the road or highway which again causes damages the the pavement. Damages from thawing are just as severe if not even more extreme than frozen damages as they occur to the upper structure of the pavement rather than the base structure. In some areas during the winter months actual federal weight limits for the trucking industry (80,000 pounds gross) have been reduced with a reduction in driving speeds as well. This reduction has been observed as high as 35% in weight and even more in maximum speeds. Some States and Providences close winter and spring travel in certain areas.
It is very important that managers of trucking and transportation companies are aware of the open and closed months, days and times these particular laws are in effect as you can’t make an arrangement with a customer to ship their item if the state will not let you ship it due to frost or thaw laws being in effect. We are creating a contact list (EDIT ADD LINK) of each state that has frost laws enacted for the trucking industry for you to contact for further information.
It is important for you to check with the DOT, DMV, Port of entry or governing office of that particular area for clarification of the specific rules and regulations.

Length: The overall maximum length allowed in Alberta without a permit is 23 meters (75′ 3″). Width: The maximum width allowed is 2.6 meters (8′ 6″‘). Height: The maximum height allowed in Alberta is 4.15 meters 13′ 7″. Weight: 6,000 kg maximum on steer axle. Tandem axles: 17,000 kg. Tridum axels is 17,000 kilograms (37,478.6 lbs) as well. All axle weights are subject to the size of the tire. Overhang: We have no information on allowable overhang in Alberta. Please share your knowledge with others below. Notes:
* Super single tires require “New Generation, Wide Base” tires with a minimum tire width of 445 mm. Available by permit only. Super single tires do not apply to the steering axle.
** These weights for tridem axles apply to provincial highways only. The maximum weight for a tridem axle on a municipal road is 17,000 kg. Permits may be available to achieve heavier weights.
*** All axle weights are subject to minimum tire size. The maximum weight per tire shall not exceed the lesser of the tire manufacturer’s weight rating or the width of the tire stamped on the sidewall multiplied by 10 kg/mm.

Routine trucking permits.
Oversize and overweight trucking permits that are routinely issued by the Alberta DOT:
Length: 52 meters (170′ 8″) is about the maximum length you can get by with on a routine permit. Width: 14′ 7″ wide depending on routing for routine trucking permits. Height: 5.3 meters (17′ 5″) in height is the cut off point for routine permits of course contingent on routing. Weight: Weight is where you run into a problem. Alberta wants to know every single detail down to the size of tire you are running. Routing being a huge issue we can’t state a “routine” weight as it all depends on your axle spacings, combinations and tire sizes. Just for a safe number we’re going to say a routine permit caps out at 43,359.2 kilograms (100,000 lbs). Overhang: 6.09 meters is about the most you can get on routine depending on routing.
Superload information.
Alberta superload information:
The maximum width normally allowed is 7.32 meters (24′) so anything over this width is a superload. We are researching information pertaining to shipping superloads in the province of Alberta Canada. If you happen to have expertise or knowledge of trucking superloads in this province please share your information for our other viewers below. Thank you.
Permitted travel times & restrictions.
Alberta DOT travel times and restrictions for oversize and overweight trucking:
The rule of 1/2 hour before sunrise until one full hour after sunset is observed in Alberta. Travel is allowed on Fridays until 3pm in the afternoon for loads that exceed 3.85 meters in width (12′ 7″) (WE WILL NEED TO DOUBLE CHECK THIS AS IT WAS LEFT AS A CORRECTION COMMENT BELOW). Travel is otherwise allowed and unrestricted on Saturdays unless stated on your permit. Night travel is permitted for loads that are over length as long as you have 1 rear pilot car/escort vehicle and are on multiple lane roads. If your shipment is no longer than of 42 meters (137′ 10″) on a single lane road you will be required to have1 front pilot car/escort vehicle and 1 rear pilot car/escort vehicle. Weekend travel is permitted for loads that are over length only. If your shipment is in excess of 4.45 meters (14′ 7″) in width you will be permitted to travel only during daylight hours. If over 3.85 meters (12′ 7″) in width you may not travel on Sundays. There is not travel permitted on the following holidays: New Years day, Provincial day, Good Friday, Victoria day, Canada day, Family day, Labour day, Thanksgiving day, Remembrance day, Christmas day and on Boxing day.
Adverse weather conditions: If adverse weather conditions are reported you may not proceed with your shipment and are required to remain where ever you are. If adverse weather conditions interrupt your shipment you are required to pull over at the nearest suitable location even if it is on the side of the road unless you are over width. Over width loads must continue until they are able to completely turn off of the road and remain until adverse weather conditions stop. If your shipment is over 4.45 meters (14′ 7″) in width or 5.32 meters (17′ 5″) in height you are not permitted to travel with snow or fog visibility less than 150 meters (492′), if the road is covered with snow or ice or sleet or any other conditions that may effect the driver from proceeding with the absolute safety in mind first and foremost.
Frost laws: Alberta does have frost laws but when they are in effect changes every year based on testing with a heat flow model that measures to 30 cm below the surface. So, if you are shipping during the spring months you will need to call the number below for the exact frost law restriction dates. There are exemptions which include milk and bread trucks, farm machinery, water, fuel, fertilizer, mail and buses.
When pilot cars are required.
If your shipment is in excess of any of the following you will be required to have a pilot car escort you:
Length: If your shipment is in excess of 34 meters (111′) in overall length you are required to have 1 rear pilot car on single lane roads. For shipments in excess of 38 meters (124′ 8″) you are required to have 1 front pilot car/escort and 1 rear pilot car/escort. Width: If your shipment is in excess of 3.85 meters (12′ 7″) wide you are required to have 1 front pilot car/escort on a single lane road or one rear pilot car/escort on multiple lane roads. For shipments over 4.45 meters (14′ 7″) wide require 1 front pilot car/escort and 1 rear pilot car/escort on single lane roads. If your shipment is in excess of 5.5 meters (18′) you are required to have 1 front and 1 rear pilot car/escort vehicle on all roads. Height: Alberta does not normally use pilot cars with high poles as they have designated routes for shipments that are over height. You can view the routes on the Alberta DOT high load corridor page located here.
Weight: As long as your shipment can maintain the minimum required speed limit you will probably not be required to have a pilot car/escort by the Alberta DOT. Overhang: If you have overhang that is over 6.5 meters (21′ 4″) you will be required to have 1 rear pilot car/escort vehicle. If your shipment overhang is in excess of 9 meters (29′ 6″) you will be required to have 1 front and 1 rear pilot car/escort vehicle.
Pilot car requirements.
Pilot car (escort vehicle) requirements for operating in Alberta province are as follows:
Pilot car/escort vehicle operators are NOT required to take any sort of DOT certification course in order to operate in Canada. Your vehicle is required however to have a lighted sign box that is a minimum of 180 cm x 35 cm x 10 cm (72″ x 14″ x 4″), 2 – 175 mm (7″) diameter flashing lights mounted on the top of the sign box on each side with 2 amber strobing or rotating lights a minimum of 203 mm (8″) mounted between the flashing lights on top of the box as well. The sign box must light up and be visible from a minimum distance of 200 meters (656′). The sign box must have either a red and white D sign or a yellow with black lettering stating “OVERSIZE LOAD”, “WIDE LOAD”, OR “LONG LOAD”. If you have the “D” sign your letter must be no less than 20 cm (8″) in height with a 4 cm (1 5/8″) line thickness. If you have the yellow sign your lettering must be no less than 20 cm (8″) with a 4 cm (1 5/8″) line thickness. The sign box must be mounted on the top of the vehicle and covered when not in operation.

Nevada maximum load limits until a trucking permit is required:
Length: 75 feet maximum overall. Maximum trailer length is 53 feet. Width: 8 feet 6 inches. Height: 14 feet. Weight: GVW 80,000 pounds. Single axle 20,000 pounds, tandem axles 34,000 pounds, tridem axles 42,000 pounds. Steer axle maximums require some math obviously. Here’s what the NVDOT says about it: “The maximum weight per tire, measured by pounds per inch of tire width, is 600 pounds per inch for the steering axle and 500 pounds per inch for all other axles, not to exceed the axle rating”. We say good luck with that, 12,400 pounds average??? Overhang: The maximum overhang allowed is 10 feet which overall must NOT exceed the maximum length of 75 feet.
Routine oversize and heavy-haul trucking permits.
These maximum dimensions/weights are considered routine oversize or heavy-haul trucking permits in NV:
Length: There really isn’t any routine maximum length. It all depends on proposed route and the state. After 105 feet in length it can get complicated. Width: 17 feet. However some routes are restricted, see notes below; Height: 16 feet. Weight: Single axles 20,000 pounds, tandem axles 46,725 pounds, tridem axles 58,000 (to 59,000 see below) pounds. Determined by bridge formula, desired route, tire size and axle spacings especially for singles, tandems, tridums and quadem axles. Gross weights are: 5 axles 92,000 pounds with 70 feet minimum axle spacings, 6 axles 96,000 pounds with 70 feet minimum of axle spacings, 7 axles 101,000 pounds with 70 feet minimum of axles spacings, 8 axles 106,000 pounds with 70 feet minimum of axles spacings. Overhang: No more than 15’ combined total but you want to check with them to make absolute sure as routing can effect this limit. Notes: For weight restrictions Nevada has different routes marked. Choose the map you need for the entire state, western, eastern and southern restricted areas. You can also view a list. For purple, orange and green areas. Also, restrictions for width and weight are in effect on the following routes: route map, route list. Also note to get the extra 1,000 pounds as noted above (59,000 pounds on tridem configurations) you are allowed to use up to 2 tridem configurations only. Any additional tridem axle configurations will max out at 51,000 pounds. If you have tridem configurations on your tractor that will be counted as 1 of the 2. However, the distance between the steer axle and the center tridum axle must be a minimum of 18 feet. It is possible to to exceed this within reason but is reviewed case by case by the NVDOT permitting office.
Nevada superloads.
Requirements for extra-heavy or over-dimensional (superloads) in NV:
Nevada is picky about weights and heights. Rather than attempting to illustrate a list of items that may not apply we suggest if your shipment does not fall within the set maximums listed above it’s more than likely going to be considered a superload by NVDOT. The permitting process for superloads is different than the normal oversize or over-weight trucking permits in Nevada and must be fully drafted by the company or person requesting the permit. For instructions for the format your super-load application must be in see: Nevada-superloads.
NOTE: any special purpose or special needs loads that are outside of the normal permitting parameters will classify as a superload.
Legal travel times for oversize and heavy-haul loads.
Travel times and restrictions:
Remember to refer to your actual permit for travel times and restrictions. For Nevada daylight travel hours are defined as one half hour before sunrise to one half hour after sunset with some restrictions; under 12 feet wide, 110 feet long or 15 feet tall may also travel during night hours and on weekends as long as you are not on I-80 between Sparks, NV and the CA state border or on I-15 between Las Vegas and the CA state border. There are no weekday curfews for any cities and if your load is under 12 feet wide, 100 feet long or 15 feet tall you may travel on holiday. However, if your load is in excess of these dimensions holiday travel restrictions are on the following days: New Years day, Memorial day, Independence day, Labor day, Thanksgiving day and Christmas day. If a large event is predicted to create dense traffic they may restrict that date as well, ie: state fairs, etc.
When pilot cars or escort vehicles are required.
Heavy-haul or oversize loads may be required to be accompanied by a escort vehicle or pilot car if:
QUICK REFERENCE
Length:
over 105 feet in length requires on escort. This applies to both 2 lane and 4 lanes roads.
Width:
2 lane roads:
12 feet requires 1 pilot car or escort.
14 feet requires 1 pilot car and 1 escort.
16 feet requires 3 total pilot cars and escort vehicles.
17 feet will require a review which will probably require 1 pilot car and 1 escort and 1 police escort.
4 lane roads:
14 feet requires 1 pilot car or escort.
16 feet requires 1 pilot car and 1 escort.
17 feet requires 1 pilot car and 1 escort and 1 police escort.
Height:
if over 16 feet and 6 inches in height you will be required to have 1 pilot car equipped with a height pole.
DETAILED REFERENCE
Length: If shipment is over 110 feet in length you are required to have 1 pilot car behind the shipment. Width: If your shipment is over 12′ wide on up to a 3 lane road you are required to have 1 escort vehicle in the front of your shipment. If over 14′ wide on up to a 3 lane road you are required to have 1 escort in the front and 1 pilot car in the rear of the load. If over 14′ wide on a 4 lane road you are required to have 1 rear escort. If over 16′ you are required to have 1 front pilot car and 1 rear escort on 4 lane and all other roads. Height: Loads that are in excess of 15′ 6″ are required to have a front high pole pilot car at all times. Weight: Pilot cars and escorts are usually not required on shipments over weight that are able to maintain the minimum posted speed requirements. If you are not able to maintain minimum speeds you will be required to have a minimum of a rear escort vehicle if travelling in urban and some rural areas. Overhang: If in excess of 25 feet you will be required to have a minimum of 1 pilot car. Notes: Some routes are completely restricot car.ted. If in the Hoover dam vicinity shipments are not permitted for anything over 10 feet in width but if 10 feet will require 1 pilot car and 1 escort.
Pilot car and escort vehicle requirements, certifications.
In order to operate a pilot car or escort vehicle in the state of Nevada you are required to have a minimum of the following:
First of all the state of Nevada requires that all pilot and escort vehicles be certified. If you are officially certified by another state then this is recognized by the state of Nevada as valid certification and you may operate within the state however, in order to have an amber light mounted to ANY vehicle you must first obtain a permit from the state which costs $2.00 per vehicle, per year. You can do that online by clicking here.
A pilot car or an escort vehicle is required to be equipped with a strobing or flashing amber light that is visible from a distance of no less than 500′ in daylight and from all 360 degree angles, mounted to the roof and above signs. The light must be a minimum of 50 candle power and if it is a rotating light must have a lens of no less than 5″ in diameter with a flash count or not less than 50 per minute. Any vehicle used for this purpose must be no less than 60″ in width, with a wheelbase of a minimum of 95″ with no more than 2 axles and a manufacturer’s gross weight of no more than 16,000 pounds.
Each vehicle must be equipped with a two way radio that is in constant contact with/to all parties involved in the shipment, 5 pound (minimum) fire extinguisher, 3 bi-directional 18″ road triangles, 1 stop/slow sign with 5′ pole handle, 1 hard hat, 1 reflective safety vest, a copy of the ANSI/ISEA manual which can be ordered online here for $30. Drivers must be a minimum of 18 years of age, have a valid drivers license, and must be flagger/flagman “capable or carrying out flagging responsibilities” (we strongly suggest a flagger safety class) of controlling traffic, wearing a approved safety yellow-green safety jacket or vest and equipped with a red flag and a stop/slow paddle of no less than 18″. Each vehicle should be equipped with proper signs that specify “oversize”, “oversize load” or “wideload” as well as “long load” with black letters a minimum of 10″ in height with a letter thickness of no less than 1 5/8″ on a yellow background which are removed or covered while not in work transit mode. Pilot car and escort vehicles must have a placard on each side of the vehicle with the companies name and phone number clearly visible from a distance of no less than 50′.
Operators of pilot cars and escort vehicles will maintain a reasonable distance from the shipment which all depends on weather, traffic, road conditions and the speed you are travelling with reasonable distance defined by how much time it takes for the shipment driver to recognize your indications to stop, slow or pass as necessary.
Shipment, truck and trailer markings.
Truck, trailer and shipment required signs, banners and flags:
All trucking companies that are hauling oversize and overweight shipments must have a amber colored strobing or flashing light affixed to the top of the tractor trailer cab that is visible 360 degrees from a minimum distance of 500′. Signs that state the nature of the shipment; “oversize load” or “wideload” signs in the overall front and rear of the shipment. Signs will be no less than 7′ in width and 18″ in height with black lettering no less than 10″ in height with a lettering thickness of no less than 1 5/8″ thick on a yellow background. Signs must be mounted securely and free of any dirt or debris. Warning flags are to be used only in daylight hours and must be florescent orange in color with a minimum size distance of 18″ from one corner to the next corner and be placed at the outer most corners of the shipment as well as on any protrusions. IF the shipment is permitted to travel during night hours must have 2 constant display amber lights placed at the very most front extreme of the shipment, two amber steady burning lights on the outer (side) center of the shipment and two red steady lit lights on the outer most rear of the shipment. THIS INCLUDES OVER-WEIGHT LOADS MOVING AT NIGHT.
Frost laws and restrictions for Nevada state.
Frost and thaw laws for Nevada:
Nevada is fairly elusive on frost and thaw law travel restrictions. They do provide a map but there is not much detail on it as far as the exact roads that must be travelled. You can view the frost law map or view this thaw law material published by the state DOT which does reference it as well. Then they also have some basic shipment route information that references it as well for the state of Nevada.

Saskatchewan maximum load limits until a trucking permit is required.
Legal Loads: Length: 75 feet (22.86 meters) overall long. Trailer length maximum is 53 feet (16.1544 meters). Width: 8 feet 6 inches wide (2.5908 meters). Height: 13 feet 6 inches (4.1148 meters) tall. Weight: 12,100 pounds (5488.4677 kilograms) on steer axle, 20,200 pounds (9162.5659 kilograms) on a single axle, 37,400 pounds (16964.355 kilograms) on tridem axles. Overhang: Kingpin settings and trailer wheelbase positions are important. Call to clarify.
Routine oversize and heavy-haul trucking permits.
These maximum dimensions/weights are considered routine oversize or heavy-haul trucking permits in SK.
Length: Since Saskatchewan Province has no said length restrictions your overall length approval will depend on your proposed route. Width: No set maximums, depends on routing. Height: No set maximums, depends on routing. Weight: Saskatchewan is tough. No single axles numbers, 48,000 pounds (21772.434 kilograms) on tandem axles, 72,000 pounds (32658.651 kilograms) on tridem axles, if you are over 60,000 pounds (27215.542 kilograms) on tridem axles prepare for a bridge survey as it will probably be required.. Overhang: No set limits, depends on routing.
Saskatchewan superloads.
Requirements for extra heavy or extra legal/dimensional (superloads) in SK.
Typically so we’re not publishing too much information a superload is defined by Saskatchewan Province as any shipment with weights and dimensions that exceed those published above in “Routine Permits”. There are exceptions but everything depends on proposed routing and road/weather conditions and if frost laws are in effect.
Required flags and markers for oversize/heavy-haul shipments loaded onto truck trailers.
Know how to mark your load and what signs are required by your permit.
Lights, flags and markers:
If over 120.078 inches wide (3.05 meters) you will need amber lights for night running and flags for daytime travel. A WIDELOAD or “D” sign is required for all wideloads over 120.078 inches wide (3.05 meters) however a “OVERSIZE LOAD” banner is NOT allowed. If you are moving at night any required banners must be illuminated with additional amber light in the center of the rear. If over 10′ 9″ (3.2766 meters) wide the cab of the tractor must be mounted with an amber light. If over 82 feet (24.9966 meters) long you MUST have a “D” sign or LONG LOAD banner mounted on the rear. If not transporting a load you must cover ANY signs.
NOTES: Lift axles are not permitted. Flip axles can be used if trailer king pin to center distance is is less than 45′ 5″, the trailer is no longer than 53′ and the load is classified as NON DIVISIBLE. A tractor wheelbase from the center of the steer axle to the center of the drive axle can not measure over 244″ unless you permit the load with a longer wheelbase AND IF they approve it. This only applies to oversize permits and overweight will not be eligible. A tridem drive tractor is NOT recognized by the Province of Saskatchewan except for moves that are large and NON DIVISIBLE, IF a tridem drive tractor IS allowed it MUST have a wheel base of no less than 260″ and no greater than 268″. A spread axles trailer that has axles spacings of greater than 6′ is considered a single axle for weight calculations and is not allowed to carry more than a combined total weight of 20,000 pounds or 10,000 pounds per axle. EXCEPT when in the case of when the object being shipped is NOT over 37,500 pounds loaded on the spread. Please leave Saskatchewan experiences below. This is a tough Province to get solid numbers out of and our viewers can use your experience to help them.
Will your shipment be delayed do to frost and thaw law restrictions?
Frost and thaw laws constantly change due to weather conditions in Saskatchewan. Find out if there in effect:
Saskatchewan Province does have spring weight restrictions and the roads and highways are dependent on conditions. These restrictions usually apply to all secondary roads and not main highways. Overall weight reductions may be imposed in some areas. Check with Saskatchewan Province permit office for clarification.
Saskatchewan travel times and restrictions.
Make certain you don’t ship oversize or heavy-haul loads during restricted movement hours:
Travel times and restrictions:
Holiday restrictions vary, contact SGI permit office to see if you can travel or not. Daytime travel only for loads over 82′ in length, 12′ 2″ in width and 16′ in height. No movement is allowed on Friday after 3:00 pm from July 1 until Labor day. Night time travel is permitted if under the above maximums but must have amber lights on all 4 outer most corners and reflective sign on rear indicating OVERSIZE or LONG LOAD.
When pilot cars or escort vehicles are required.
Heavy-haul or oversize loads may be required to be accompanied by a escort vehicle or pilot car if:
Length: If load is over 98′ on 2 lanes 1 rear pilot car (escort) is required. If over 118′ in length 1 front and 2 rear pilot car (escort vehicle) is required. Width: If a load goes beyond the center line of the road then 1 front escort is required. If over 16′ 4″ wide you will be required to have 1 front and 1 rear escort. Height: Up to the permit office depending on route. If over 17′ 2″ in height you will be required to have a bucket truck travel with you. Weight: For over weight shipments it looks like an escort vehicle will not be required. Overhang: Case by case basis. Contact permit office for clarification.
Pilot car and escort vehicle requirements.
Pilot car or escort vehicle mandatory operator certifications and vehicle requirements:
All pilot cars/escort vehicles must display a bumper or roof mounted “OVERSIZE LOAD” sign visible from both the front and rear of the vehicle.

Locate trucking companies and pilot car companies in Manitoba, Canada.
Length: The overall maximum length without a permit is 23 meters. Width: The maximum width allowed without a permit is 2.6 meters. Height: 4.15 meters is the maximum height allowed by Manitoba DOT without a permit. Weight: 9,100 kg on steer (seems high to us so NOT a confirmed number – use reference link below), tandem axles: 17,000 kgs, tridem: 17,000 kgs, or 3 axle combination with proper spacing of a 23,700, quadem: 31,600 kgs, 5 axle: 39,500 kgs and 6 axles: 46,500 kgs. Let me refer you to our reference on this for clarification from Manitoba DOT as there are different weight classes. Overhang: Our researchers are unable to find any information on maximum allowed legal overhang. We did find the pilot car requirements of 25 meters. We will call and update at a later time or you can call Debra Martin at: 204-326-8292 M-F 8-4 – if you do please comment below as this author is writing on a Sat. and they are closed. Thank you!
Routine oversize and heavy haul trucking permits.
Oversize and overweight trucking permits that are issued routinely by Manitoba province:
Length: 30 meters on length is about all you are going to get. Width: 5 meters wide for routine permits depending on routing. Height: Depending on routing as Manitoba DOT has designated routes the maximum height is 4.8 meters. Weight: We were unable to get a solid figure. Manitoba DOT has different zones for weight restrictions so it all depends on which zone you need to travel in. See Manitoba DOT zone map. Overhang: Based on the comment they made on 25 meters of rear overhang we are going to say that up to this amount is routine. If you need to speak to them call the number located above in “legal load limits” in the “overhang” section.
Superload information.
Manitoba DOT information on suplerloads or extra ordinary loads:
We will do more research on superloads in Manitoba in the future. The Manitoba DOT documentation does not cover or mention much about them so we will need to speak with someone on the phone. We are able to see that they are well versed in shipping superloads as they mention in their online documentation that there will make arrangements to remove road side signs and replace them for shipments that are in excess of the road width. We will get back to this section soon but in the meantime appreciate any comments you may be able to leave for other visitors below.
Permitted travel times for oversize and heavy-haul loads – restrictions.
Manitoba DOT permitted travel times and restrictions:
Daylight travel times are defined as from sunrise to sunset in Manitoba. No travel is permitted after 3 PM on Fridays during the summer months for shipments in excess of 3.4 meters (11′ 2″) wide on seasonal restricted roads. In the spring shipments in excess of 4.6 meters (15′) in width are not allowed to travel on roads during the spring restriction times. On routes that are not seasonally restricted you may proceed (multiple lane roads) until 3 PM as long as you are no wider than 3.7 meters in width (12′ 2″) on Friday and resume travel on Saturday at sunrise however if you are in excess of 25 meters in length (82′) you are not permitted to travel after 3 PM on Fridays during the summer months if you are on a seasonally restricted highway and resume on Saturday at sunrise – you are allowed however to travel on holidays. Sunday travel is permitted for loads up to 3.85 meters (12′ 7″) in width on all roads that have no seasonal restrictions. On a single lane highway on holidays you can not exceed 3.4 meters (11′ 2″) in order to travel. On multiple lane roads you can travel only if you are less than 3.7 meters (12′ 2″). This is very confusing so always refer to your permit for final verification but to help the matter lets go over the restricted routes:
Highway 1 from Falcon lake to the Manitoba/Ontario border.
Highway 6, 8, 9, 15, 16, 44, 307, 313, 317.
Highway 10 from the US border to Riding Mountain National Park.
Highway 11 but only north of highway 44.
Highway 12 but only north of highway 15.
Highway 59 from the west boundary line of Brokenhead to Grand Beach and the South perimeter of St. Malo
Here is the Manitoba link for spring road restrictions with zones to help you with interpretation. Holidays observed are: New years day, Provincial day, Good Friday, Victoria day, Canada day, Family day, Labor day, Thanksgiving day, Remembrance day, Christmas day and on Boxing day.
When pilot cars are required.
Manitoba DOT requires you to have a pilot car if your shipment is in excess of any of the following regulated limits:
Length: Shipments that are in excess of 30 meters (98′ 5″) long require 1 pilot car/escort vehicle on the rear of the shipment on all roads. For shipments that include a booster of a jeep that are over 31 meters (101′ 9″) you are required to have 1 rear pilot car vehicle on all roads. Width: If your shipment is in excess of 4.6 meters (15′) wide then you are required to have 1 front pilot car on single lane roads and 1 rear pilot car/escort on multiple lane roads. If your load is in excess of 3.66 meters (12′) but less than 4.55 meters ( 14′ 7″) then you are permitted to travel at night as long as you have 1 front and 1 read pilot car/escort vehicle on all roads and highways. Mobile homes can travel at night on multiple lane roads as long as it does not exceed 5 meters wide (16′ 4″) but are required to have 1 pilot car on the rear. Height: If you are approved for a shipment that is over the legal limits Manitoba DOT has designated routes and you are not required to have a pilot car. Weight: As long as your shipment is able to maintain the minimum speed requirements you will more than likely not be required to have a pilot car as long as your shipment is overweight only. Overhang: Overhang is approved on a case by case basis. Check with the Manitoba DOT for further information to see if your shipment will require a pilot car due to excessive overhang.
Pilot car certifications.
Manitoba DOT certifications and requirements of pilot cars (escort vehicles):
Pilot car/escort vehicle operators are required to take a Manitoba DOT certification course in order to operate in this province. The certification program is recognized by all US jurisdictions that require PEVO except for New York state.
