Ontario Frost Laws

2020 Ontario winter frost/spring thaw laws and seasonal weight restrictions.

Frost - thaw laws Ontario.

Restrictions during winter frost and spring 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/thaw laws and seasonal weight restrictions. 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 damages to public assets and protect public investment in the roadways.

Frost/thaw damages to surface.

Learn the details of the winter frost laws, spring thaw laws and seasonal weight restrictions. Details for the USA and Canada by State/Province. Many areas incorporate temporary special weight limits and restrictions (frost or thaw laws) during the winter and spring months of the year. These temporary restrictions are usually referred to as “frost laws” or “thaw 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 officials to verify the latest changes in the laws.

Why we have these laws and must protect our roads and highways.

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 (ie: -10 below zero) 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 the spring and winter months (specifically trucking companies) when the roads and bridges are thawing out. 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 legal axle weight limits be decreased by as much as 35%. Some areas and local governments may also limit heavy-haul vehicle speeds to a maximum of 35 miles per hour during frost/thaw law months regardless of posted limits.

One of many examples is in Southern Oregon on old US Highway 1 (which follows the coast line from Mexico to Canada) the road is as much as 16 feet thick as years of pavement (even bricks) has been laid down year after year since the early 1900’s. 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.

Frost and thaw laws.

Frost and thaw laws:

Frost and thaw laws are in effect usually from March 1 until mid June on major routes, southern central and the interior. There are so many roads that have different regulations on thaw laws and frost laws. You absolutely will want to call the Alaska State DOT office at the number below for more information. Example: A particular highway may have a set of regulations until you reach a certain mile post, then after that has a whole different set of regulations. There are hundreds of them similar.

All of this depends entirely on the route you choose to travel as well as distance and any bridges that you intend to cross. It also depends upon the length, height and width of the shipment. Between the months of October 1st and March 31st for one, two and three drive axle groupings on trucks and truck tractors traveling the Elliott, Steese and Dalton highways between Fairbanks and Prudhoe Bay you can shift legal axle weights in the following weights on these routes in applicable: single axles 22,000 pounds (with 8’1″ minimum axle spacing). Tandem axles 42,000 pounds, tridem axles 48,000 pounds. The maximum height allowed is 15’3″. Shipments over 14 feet wide or 150 feet long or 16’6″ in height must supply to the permitting department the exact route they wish to travel.

Heavy haul and oversize truck signs and flags.

A standard oversize load sign is required on the front of the tractor and the rear of the shipment if it exceeds 8’6″ and width. The sign must be yellow and have a minimum of 48 inches in width with black letters that are 10 inches tall and 2 inches wide. Acceptable signs when specified shall read “oversize”, “oversize load” or “wide load” for over width vehicles and/or shipments “oversize”, “oversize load” or “long load” for over length vehicles must be affixed to the rear of shipment when overall load exceeds 60 feet in length. Vehicles and loads with rear overhang exceeding 10 feet are subject to the following: must have “oversize” or “oversize load” signs and a amber high intensity rotating, flashing, oscillating or strobe type beacon which must be visible for a minimum of 500 feet from the end of the shipment. You must have either an extended light-bar or a rear pilot car or escort vehicle. All flags must be a minimum of 16” square and must be red. Flags are required to be on vehicles with loads wider than 10 feet and if overhang exceeds the legal limits in any direction.

Pilot car and escort vehicle requirements.

If the width of the shipment is over 10’6″ and up to 12 feet one pilot car or escort vehicle is required. For lengths over 85 feet and up to 100 feet one pilot car is required. If overhang is greater than 10 feet but less than 20 feet one pilot car or escort vehicle may be used. It is possible to use an extended lightbar and place of a rear pilot car. Heavy haul or overweight shipments with special bridge conditions are required to have two pilot cars if the width is 12 feet up to 14 feet to pilot cars or escort vehicles are required if the length is greater than 100 feet to escort vehicles or pilot cars are required. If the overhang exceeds 20 feet unless the rear is greater than 35 feet or the front greater than 60 feet one pilot car is required. For widths over 14 feet three pilot car vehicles or escort’s are required: two in the front and one in the rear. If you have overhang from the rear that is greater than 35 feet to pilot cars are required and for widths up to 18 feet but not more than 22 feet 4 pilot cars or escort vehicles are required. If road closures exist and you are an excess of 22 feet wide then you will be required to have 5 escorts or pilot cars. You may be permitted to use an extended light-bar when up to 20 feet of rear overhang and lieu of a rear pilot car.

Pilot car and escort vehicle requirements.

Pilot cars and escort vehicles may be passenger trucks and cars as long is they are under 10,000 pounds in total weight. Pilot cars and escort vehicles must carry commercial vehicle insurance. Pilot cars and escort vehicles will not carry any passengers. Pilot cars and escort vehicles will not act as a steer man or a tiller man for any load. Oversize load signs and beacons: all escort vehicles and pilot cars are required to be equipped with the appropriate signage. Depending upon the shipment you are working with this might be oversize, wide load or long load and the sign must be roof mounted with a high intensity rotating flashing oscillating or strobe type amber beacon light which must be visible from a minimum of 500 feet in any direction. When a pilot car or in escort vehicle is required to lead any oversize load the appropriate sign must be faced towards the front of the pilot car or escort vehicle when the pilot car or escort is chasing a load the appropriate sign must be faced towards the rear of the vehicle. Pilot car companies and escort vehicle drivers shall carry the following items and equipment at all times when escorting heavy haul and oversize loads: a 24 inch stop slow paddle sign, three bidirectional emergency reflective triangles, 15 pound rated B and C fire extinguisher, a reflector rise orange vest shirt or jacket, a first aid kit, a flashlight with extra batteries, a red cone and be equipped with a red hand flag.

Flag men or flag persons.

The state of Alaska does not require a pilot car or escort vehicle operator to have certification to perform flagging functions flaggers and or pilot car or escort vehicles operators shall complete the state approved flagging test as well is any necessary training prior to working in the capacity of a flagger. There is a fee for the online class. Flag persons shall not be less than 18 years of age and must be capable of carrying out flagging responsibilities in accordance with the Alaska state traffic manual regulations flaggers must be wearing high visibility or florescent orange jackets and vest as well as equipped with a slow stop paddle and a red hand flag these items must be utilized by the pilot car company or escort vehicle operator in the event that it becomes necessary. If required pilot car and escort vehicle operators will need to pull over and Park in order to stop or control Highway traffic. At no time shall the slow stop paddle or red flags be displayed out of the window of a moving vehicle.

Travel time for heavy haul and oversize loads.

Heavy haul permits and oversize trucking permits are valid for 3 to 5 days unless otherwise specified. Travel is permitted from Monday through Saturday at noon during daylight hours. One half hour before sunrise to one half hour after sunset. However, vehicles that are not exceeding 10’6″ wide or 16 feet tall or 85 feet and linked total may travel Monday through Saturday during daylight hours. Oversize vehicles are allowed to operate during hours of darkness under special lighting and taping requirements. Travel is permitted on the following holiday weekends memorial day for for July and Labor Day. Urban areas do restrict travel during peak hours be sure to refer to your permit for specific travel times especially in urban areas.

Spring weight and frost laws.

Weight restrictions and frost laws usually occur on all major routes in South, Central as well as interior Alaska. Typical months are from March 1st until the 1st July.

The information contained in these pages is research information primarily for use by oversize and overweight trucking company drivers, dispatchers and pilot car companies. While every effort is put into maintaining the accuracy of this information you must absolutely verify this information with the Alaska State DOT Permits office before commencing movement.

Legal load limits.

Alberta DOT legal load limits:

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.

2019 Arizona State Shipping Regulations

2019 Arizona state shipping laws, regulations, rules and limitations for oversize and overweight trucking on state highways and roads.

Arizona

The great state of Arizona official seal.

Please share your expertise of Arizona state DOT trucking regulations with other visitors below.

As per the state of Arizona please read the following:

“The Arizona Department of Transportation in cooperation with state representatives, industry, the Department of Public Safety  and local law enforcement personnel work in collaboration to update and amend oversize and overweight special permit rules containing special permit requirements, restrictions and allowances for transporting oversize and overweight vehicles and loads on highways under the jurisdiction of the Department. This is a council established in statute and makes up the Over-dimensional Permit Council.

These rules detail the eligibility, application and use requirements for a variety of permits the Department currently issues to commercial motor carriers for transporting vehicles or vehicle and load combinations exceeding the maximum size or weight limitations provided by statute.

Each special permit provided by the Department under these rules is specifically authorized by statute.  The oversize and overweight special permits issued under these rules are that each permittee issued a particular class of permit is subject to the same activities, practices, requirements and restrictions applicable to that permit type. The statutes additionally provide authority for issuance, conditions, restrictions, approvals and fees.”

Gross weight maximums: 5 axles is 104,000 pounds, 6 axles is 108,000 pounds, 7 axles is 117,000 pounds. The permissible maximum weights depend on the number of tires combined with the overall distance between each of the axles. Spacings on axles are a little bit tricky in this state. The Arizona DOT permits office will consider a number or factors but it’s primarily about the bridges which could require a route survey if extreme weights are involved. If weights are excessive and trailer capabilities are even close to short of maxing out, forget it! Pavement, structural and stress testing results will govern your overall permissible capabilities.
Width: 14 feet wide maximum or file under super load.
Height: 16 tall maximum or file under super load.
Overhang:  3 feet of front or 6 feet off of the rear or any configuration that is in excess of 75 feet. They could require you to use a stretch trailer before allowing you to proceed under super load provisions.
