Required shipment, truck and trailer markings:
Truck, trailer and shipment required signs, banners and flags.

A rotating amber light must remain on at all times mounted on top of the cab and be visible from 360 degrees from a minimum of 500′ in direct sunlight. If your overall length is more than 80′ in length you are required to have one amber light over the cab of the truck and one amber light no more than 10′ from the rear of end or trailer/load at the highest point that is practicle. Oversize load signs must be a minimum of 7′ in width x 18″ in height, have a yellow background color with black lettering no less than 10″ in height x 1″ thick – we have recently heard 12″ tall x 2″ thick so please clarify and comment below if you know which is correct. Flags are required at all 4 corners of the load and front of truck and are to be safety red in color and no less than 18″ square. Shipments over 75′ in length, 10′ in width or 14′ 6″ in height are required to have signs. Signs must be placed on the front and rear extremities of the truck, trailer or load.

When pilot cars are required:

Length: If over 110′ in length you are required to have a minimum of 1 pilot car and in some places 2 pilot cars (higher traffic density or certain times of year). If over 145′ (150′ in some very rural areas) in length you are required to have 3 pilot cars –  yes 3. If over 175′ in length a police escort will be required.
Width: Up to 14’6” requires 1 pilot/escort vehicle. Over 16’ requires 2 pilot/escort vehicles. Over 18′ in width will require a police escort. 
Height: Up to 14’ 6” 1 pilot/escort vehicle, over 16’ requires 2 pilot/escort vehicles. Over 18′ in height will require a police escort.
Weight: No requirements as long as you can maintain minimum speeds. However on bridge moves that require all other vehicle traffic to be removed will required appropriate number of pilot cars which is a minimum of 2 and possibly 3 with police escort. All areas are different and require evaluation.
Note: If you exceed any two dimensions, then you are required to have an additional pilot car. So if you’re over 14′ 6″ tall and 14′ 6″ wide you would be require to have 2 pilot cars.

Required pilot car certifications:

Cars, vans or trucks may be used as long as gross weight of pilot car vehicle is rated at no more than 8,000 lbs. Pilot car driver must be 18 years of age minimum with a valid regular drivers license. Pilot cars must have a rotating or flashing amber light mounted on the top of the vehicle (no specs as of time of writing 2014).

2019 Truck Safety

2019 Truck Safety Sting Results.

12,000 trucks & 2,700 drivers were placed out of service.

The numbers are in for the Commercial Vehicle Safety Alliance’s annual International Road check enforcement sting – held June 4-6, 2019. During these three days a total of 67,072 commercial vehicles were inspected in the USA and Canada. 12,019 trucks inspected (17.9% of them) were placed out of service due to violations and 2,784 drivers (4.2% of the trucks) were placed out of service for driver related issues.

The #1 violation was brake related issues. For the driver related issues the leading violation was hours of service.

Out-of-service vehicle conditions starting with the highest:

Vehicle Violations.
1. Braking system issues.
2. Tires and wheels.
3. Brake adjustment.
4. Properly secured loads.
5. Lighting devices.
6. Suspensions.
7. Steering mechanism.
8. Other.
9. Frames.
10. Coupling devices.
11. Drive line/driveshaft.
12. Fuel systems.
13. Exhaust systems.

Driver out-of-service violations starting with the highest:

Driver Violation.
1. Hours of service.
2. Wrong class license.
3. False log books.
4. Other.
5. Suspended license.
6. Drugs/Alcohol.
7. Expired license.
8. Violating license restriction.

Road safety enforcement results.

The CVSA said 3,851 commercial motor vehicles transporting hazardous materials/dangerous goods (HM/DG) were inspected and 527 vehicles were found to have out-of-service conditions, which is a 13.7% out-of-service rate for HM/DG vehicles. There also were 52 HM/DG drivers placed out-of-service – a 1.4% out-of-service rate for HM/DG drivers.

Each year, special emphasis is placed on a certain category of violations. This year’s focus was placed on steering and suspension. Inspectors found 408 steering (2.5% of all out-of-service vehicle violations) and 703 suspension issues (4.3% of all out-of-service vehicle violations) during the International Roadcheck Enforcement sting.

During the three International Roadcheck Enforcement days the inspectors primarily conducted one of three inspection levels:

The North American Standard (NAS) Level I Inspection is a 37-step procedure that includes an examination of driver operating requirements and the vehicles overall mechanical fitness.
The NAS Level II Inspection typically includes everything that can be inspected without physically getting underneath the vehicle.
The NAS Level III Inspection is a review of driver requirements such as the drivers license, documentation (vehicle and load), log books, seat belt usage, etc.

It would be nice if we were given some numbers for the percentage of the trucks that serviced the OS/HH industry. Either way one must admit these numbers aren’t a good reflection on our industry overall and these numbers can’t be ignored – especially when the main issue involved are the breaks. We couldn’t also help but to note the amount of violations for incorrect drivers license or suspension. One has to wonder if a insurance claim had to be filed for whatever reason if it would be valid (at all) since the actual driver of the truck wasn’t supposed to be behind the steering wheel in the first place. This is dangerous territory for everyone involved including the public.

Interesting fact as well:

3,085 actual truck driver jobs have been lost due to companies going out of business so far in 2019.

We’d be happy to hear your comments below.

Saskatchewan Frost Laws

2020 Saskatchewan frost laws, seasonal load weight and speed 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.

Prince Edward Island Frost Laws

2020 Prince Edward Island frost laws, seasonal load weight and speed restrictions.

Spring frost laws and weight restrictions for Island roads will begin at 12:01 a.m. on Friday, March 15, 2020.

For Prince Edward Island all weather roads, such as routes 1 and 2: Vehicles may carry up to their maximum allowable weight with no overweight exceptions permitted. Other roads: Vehicles may carry 75 percent of their maximum allowable weight during frost law (thaw law) season. Only the road’s posted weight limit is permitted and if the laws are not observed a fine may be levied.

It is important for truck drivers and trucking company dispatchers to make certain they are operating in accordance with the Prince Edward Island 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 investment in the roadways.

Late winter and early spring driving in this province has its own set of challenges. Previously frozen roads become more vulnerable to damage as they thaw out and soften. Heavy vehicles travelling over paved roads can make it worse by causing the pavement to crack and break up.

What is frost law and why are they necessary?

When pavement thaws during the daytime and freezes at night it is potentially damaging to the road. In order to prevent this “frost laws” are implemented in order to prevent costly damages to the road.

How are roads damaged by frost thawing or the road freezing?

Water from melted ice and snow seeps into cracks in the pavement and softens the gravel underneath. When the water beneath the surface freezes again, it expands and breaks the pavement, causing potholes. If ice continues to form under the pavement from a steady supply of water, it can push the entire surface of the road upward causing the washboard like unevenness (ripple) known as “frost heaving.” These damages are permanent and costly to repair.

Why are Prince Edward Island roads more vulnerable to seasonal damage?

Prince Edward Island consists of a high concentration of silty soil which collects and holds more water beneath the roadway surfaces, making the roads more susceptible to frost heaving and potholes despite any drainage measures that have been put into place.

What are the classifications of roads under weight restrictions?

  • All-weather roads, such as routes 1 and 2: Vehicles may carry up to their maximum allowable weight – with no overweight exceptions permitted.
  • Other roads: Vehicles may carry 75 percent of their maximum allowable weight.
  • Posted weight limits: Only the road’s posted weight limit is allowed.

Manitoba Frost Laws

2020 Manitoba frost laws, seasonal load weight and speed restrictions.

Manitoba Spring Road Restrictions (SRR) program.

The Manitoba Ministry of Infrastructure divides its province into three sections, with each section having a unique thaw restriction start and end date. In 2020, it will begin its spring road restrictions for Region A and Region B of the province at 6 a.m. on Friday, March 10. Weight restrictions are scheduled to end at 11:59 p.m. on Wednesday, May 31.

The allowable axle weights on weight restricted roads during the spring season are based on the percentages of the legal axle weights, with some exceptions for the single steer axles and in situations where essential commodities are being shipped. There are two levels of spring weight restrictions in Manitoba depending on the strength and surface conditions of the pavement structures. The Level 1 weight restriction applies to weak pavements while the Level 2 weight restriction applies to very weak pavements. The allowable axle weights on different axle configurations are calculated as follows:

Level 1 Spring Weight Restrictions:

  1. On a single steering axle of a single or tandem drive truck tractor:
    • 10 kg per millimeter width of tire up to a maximum of 5,500 kg on all highways.
  2. On a single steering axle of a straight truck or a tridem drive truck tractor:
    • Tire size 305 mm or less: 10 kg per millimeter width of tire up to a maximum of 5,500 kg on all highways.
    • Tire size greater than 305 mm: 9 kg per millimeter width of tire up to a maximum of 6,570 kg on all highways.
  3. On a tandem steering axle group of a straight truck:
    • 9 kg per mm width of tire multiplied by 0.90 (download factor) up to a maximum of 12,240 kg on RTAC Routes or Class A1 highways and up to a maximum of 9,900 kg on Class B1 highways.
  4. On all other axle groups:
    • 9 kg per millimetre width of tire up to a maximum of 90% of the legal axle group weights on all highways.

Level 2 Spring Weight Restrictions:

  1. On all single steering axles of all vehicle configurations:
    • 6.5 kg per millimeter width of tire up to a maximum of 65% of the legal axle weights on Class A1 and Class B1 highways.
  2. On a tandem steering axle of a straight truck:
    • 6.5 kg per millimeter width of tire multiplied by 0.90 (download factor) up to a maximum of 8,840 kg on Class A1 highways and up to a maximum of 7,150 kg on Class B1 highways.
  3. On all other axle groups:
    • 6.5 kg per millimeter width of tire up to a maximum of 65% of the legal axle weights on Class A1 and Class B1 highways.

Road restrictions for Region C, the northern most regions, will begin at 6 a.m. on Sunday, March 12, and end at 11:59 p.m. on Saturday, June 10. Region C is defined as the rest of the province north of the virtual line in Region B.

Spring Weight Restrictions are classified as Level 1 and Level 2 (see table below).

Example of Maximum Allowable Axle Weights. Level 1 Spring Weight Restriction, Reduce Axle Weights to 90% Maximum Allowable Weights. Level 2 Spring Weight Restriction, Reduce Axle Weights to 65% Maximum Allowable Weights. A complete list of Charts of Allowable Axle Weights can be found at the following link: http://gov.mb.ca/mit/srr/restrictions.html
