Saskatchewan Frost Laws

2020 Saskatchewan winter frost/spring that laws and seasonal weight restrictions.

The winter/spring season frost law restrictions will again be in in effect for many roadways in the Province of Saskatchewan this year according to information provided by the the provincial Ministry of Highways and Infrastructure. Typically, seasonal (spring) frost law restrictions that take effect in March.

Spring load restrictions on affected highways: The maximum load on steering axles is 10 kg per millimeter (560 lbs. per inch) width of tire (manufacturer’s stamped dimensions), to a maximum of 3 000 kg (6,612 lbs.) on each wheel but to a maximum of 5,500 kg (12 120 lbs.) on the steering axle; except for straight trucks on primary highways which are allowed up to a maximum of 7,250 kg (15,983 lbs.) on the steering axle with the appropriate tire size.

Maximum loads on all other wheels will be limited to 6.25 kg/mm (350 lbs. per inch) width of tire to a maximum loading of 1,650 kg per wheel (3,636 lbs.)

Maximum gross axle weights and tire sizes.

Colder temperatures during the winter months help freeze and strengthen roads. As a result more weight can be transported on provincial highways without damaging the road. This is a benefit to the trucking community.

The winter weight period that allows additional weight typically runs from November 16 through March 14. However, if weather remains mild the program may be postponed because without sufficient freezing, extra weight can damage pavement and the road beneath.

Winter Weights will not apply in the southwest area of the province until December 1 and will be removed on the last day of February due to historically milder climatic conditions.

Municipal roads are the responsibility of each rural municipality, who can set out their own weight limits. Weights can be restricted at any time by Minister’s order.

Saskatchewan is a large province with considerable difference in climate in the north and the south. The new change takes into account the climatic differences in the north and the south of the province while also maintaining the original intent of providing primary weight access for economic activities. In the north of the province, the annual weight increase on the 9-month primary highways will be same as before, from July 1 to March 31 of the following year. In the south of the province, the annual weight increase on the 9-month primary highways will occur earlier, from June 15 to March 15 of the following year. This change will help to sustain road conditions in the south, where spring thaw occurs earlier.

Additional information can be obtained by contacting the inquiry line: 1-866-933-5290 in Saskatchewan or 306-933-5290 outside the province.

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.

We must protect of 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.

Do I need a trucking permit? Legal load limits.

Georgia maximum load limits until a trucking permit is required.

Length: 75 feet maximum overall combined including overhang. However, 60 feet maximum length on some routes.
Width: 8 feet maximum on some roads but on main highways and Interstates 8 feet and 6 inches is the maximum width.
Height: 13 feet and 6 inches.
Weight: GVW 80,000 pounds overall combined. Single axle is 20,340 pounds, tandem axles is 34,000 pounds and tridem axles depends on the spacing  but is 20,340 pounds maximum on each axle in the configuration.
Overhang: Overhang in not detailed much by Georgia state DOT so if you are in excess of 60 feet in length overall combined we strongly suggest you contact the oversize permitting office by telephone below.

Routine oversize and heavy-haul trucking permits.

These maximum dimensions/weights are considered routine oversize or heavy-haul trucking permits in Georgia:

Length: Under 120 feet long was the old rule but as of 02/28/19 it seems there’s no limit on length if that is the only dimension over routine. Also a legal
Weight: Any single axle routine permit is 23,000 pounds, tandem axles is 46,000 pounds, tridem axles is 60,000 pounds, quadem axles is 92,000 pounds. Gross maximum routine permit weight limitations are: 5 axles 100,000 pounds, 6 axles 125,000 pounds, 7 axles 148,000 pounds, 8 axles 150,000 pounds. If over 150,000 pounds it’s a superload.
Width: 15 feet and 6 inches. However, on some routes 16 feet is permitted with 1 front pilot car and 1 rear escort. Mobiles and pre-fab homes are limited to 95 feet in length overall.
Height: Under 14 feet tall.
Overhang: This is a very odd state as far as overhang is concerned. Look below under superloads and try the actual state documentation or simply give them a call at the number listed below.
Notes: Georgia mentions a legal 53 trailer with no over all length restrictions on federal interstates and “STAA” designated routes. This isn’t real clear to our staff as no overhang limits would then be governed by maximum lengths. But with no maximum length if that is the only dimension that is over routine limits then we assume any length can be permitted. BE ABSOLUTELY CERTAIN TO ALWAYS REFER TO YOUR ACTUAL OVERSIZE TRUCKING PERMIT FOR ANY DISCREPANCIES.

Georgia superloads.

Georgia superload information:

Ultimately Georgia superloads are classified on a base-by-case basis if they exceed the maximum weights or dimensions mentioned above in “routine permits” however there are exceptions to the rules. We suggest for in-depth research you refer to: The Georgia state DOT laws for oversize and heavy haul trucking permits.

Legal travel times for oversize and heavy haul loads.

Travel times and restrictions for heavy-haul and oversize loads:

Georgia travel times unless otherwise stated on your permit are as follows; Monday thru Saturdays from one-half hour after sunrise until one-half hour before sunset Eastern Standard Time or Eastern Daylight time depending on spring or fall.

I-285 is the boundary for Atlanta and travel within it is restricted and not permitted at all unless you are picking up or delivering within – if so travel times are not permitted from 6 AM until 9 AM and from 4 PM until 6 PM on weekdays M-F. Shipments in excess of 10 feet in width may not travel more than 55 miles per hour. Any permitted shipment that is in excess of 16 feet in width may only travel between 10 AM and and 3 PM in and around major cities. Any permitted shipment that is in excess of 12 feet in width may not travel under any circumstances if visibility is restricted to less than 600 feet or wind speed in in excess of 25 miles per hour.

Lights, safety flags and warning signs for heavy haul and oversize loads.

Required marking, safety flags, warning signs for heavy haul and oversize loads:

Any oversize or heavy-load must be clearly identified by the appropriate signs such as “OVERSIZE LOAD” OR “HEAVY-HAUL LOAD” or other variations that are specific. Signs must be mounted on the front of the truck and rear of item being transported. Sign dimensions must be no less than 6 feet wide and 12 inches in height. Sign must have a yellow background with black letters not less than 8 inches tall. Front and rear of oversize combination must be flagged with red or orange florescent flags 18 inches square. The power unit must be equipped with a amber light – note you must purchase a amber light permit to operate one in the state of Georgia.

When pilot cars or escort vehicles are required.

Heavy-haul or oversize loads may be required to be accompanies by a escort vehicle or pilot car if:

QUICK REFERENCE

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.

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. You are also expected to have the following items inside of the vehicle: CB radio or high powered 2-way radio, first aid kit, fire extinguisher type A, B & C of at least a 2 liters, 3 reflective road triangles, 3 traffic cones, reflective vest (worn while working), slow/stop sign, 3 red or orange safety colored flags no less than 40 x 40 cm (16″ x 16″), nose cone flashlight and a hard hat.

Shipment, truck & trailer markings.

Truck, trailer and shipment required signs, banners and flags:

All trucks that are hauling oversize or overweight loads must have a strobing, flashing or rotating amber light mounted to the roof that is visible from 360 degrees at a minimum distance of 200 meters (656′). All 4 outermost corners corners of the overall shipment and any obtrusive points must have flags mounted to them that are safety red or orange in color no less than 40 cm x 40 cm (16″ x 16″) and have the flags exchanged for lighting if moving during the night. A sign stating the nature of the load; “OVERSIZE LOAD”, “WIDE LOAD” or “LONG LOAD” must be mounted to the front and rear of the overall shipment. Signs must be a minimum of 12′ in height and 6′ in width with a yellow background and black letting with lettering thickness no less than 4 cm (1 5/8″) thick.
