British Columbia Pilot Cars / Escorts

When Pilot Cars are Required 

Pilot Car requirements for oversize load moves on provincial highways will be established by the terms of the permit issued for the move. 

One or two pilot cars may be required when the load width, length, or height result in needing additional roadway space to maneuver.

Basic rules for whether one pilot car should be in front of or behind the load are set out in the Commercial Transport Regulations, section 8.08.

When two pilot cars are used, generally one is positioned as lead and the other follows the load as the rear pilot car. The main duties of the rear pilot car driver are to communicate with the load driver about surrounding traffic or other obstacles, and to monitor the load. 

Three or more pilot cars may be required for more complex moves.

The requirements and typical positioning of the pilot cars would be set out in the permit conditions and may vary depending on the locations and situations along the route.

A third pilot car would typically assume the scout pilot car position and may travel well ahead of the load and lead pilot car to identify appropriate traffic control locations or pinch points ahead of time. 

The load permit may have additional requirements. If a transportation management plan has been required as a condition of approval for the move, it may have further pilot car and traffic control requirements.

British Columbia Trip and Fuel (IRP / IFTA) Permits

Temporary Permit

Note: Vehicles licensed under 11,800 kgs (26,014 lb.) and having more than 2 axles also require a Motive Fuel User permit.  In this situation, please contact the Provincial Permit Centre at 1-800-559-9688. For more information, please refer to the Tax Bulletin: International Fuel Tax Agreement and Motive Fuel User Permits. 

British Columbia Overweight / Oversize Fines

If the dimensions or weights are different than is printed on the permit the fines will start at 100$ per occurrence and increase accordingly.

Overweight fines start at 115$ and go up 10 Canadian dollars ever 100 kilos in excess weight allowed by the permit.

Running Hours and Holiday Restrictions

Warning Lights

All trucks that are hauling oversize or overweight loads must have a strobe, flashing or rotating amber light mounted to the roof that is visible from 360 degrees at a minimum distance of 200 meters (656 ft.). Warning flags must be replaced with warning lights at the extremities of the load during the night.

Flag Requirements

Flags on an oversize vehicle or load shall be red, be mounted on all 4 corners or projections of the vehicle or load, and either be a minimum size of 30 cm square, or be in strips that are not more than 3 cm in width, not less than 45 cm in length and that cover an overall width of not less than 15 cm.

Flags, Lights and Banners

Travel is permitted 24/7 when dimensions do not exceed any one of 10 ft. 6 in. wide, 14ft. 6 in. high, or 82 ft. long. Any dimension that exceeds these is limited to daylight hours only, no Sunday travel, and no travel during the summer (last Friday in June until second Monday in September) after 2:00 pm on Friday and Saturday until 4:00 am the next day.

British Columbia Tire Regulations

As of October 1, BC law requires that all vehicles travelling on specific highways have winter tires. Along with the province, trucking associations are also reminding drivers to prepare for the winter conditions before it is too late.

A legal winter tire (on a standard passenger vehicle or a four-wheel/all-wheel vehicle) must have at least 3.5 mm of tread depth. Commercial trucks weighing between 5,000 kg (11,023 lb.) to 27,000 kg (52524 lb.) GVW primarily use chains for additional traction, but may use tires with the 3-peaked mountain and snowflake symbol or the M+S symbol if available for their vehicle class.

It is recommended that commercial vehicles use steel link chains as they have been proven to provide superior traction and prevent lateral slippage. Cable style chains are permitted if used in conjunction with steel link chains which have been installed on the outside of a drive axle. Cable chains do not provide adequate traction on roads with banked curves on their own and can actually cause a vehicle to slide.

From October 1st till March 31st all commercial trucks must carry tire chains. Studded Tires: these tires may only be used on BC highways from October 1 to April 30 and the studs should not protrude more than 2 mm from the tread or traction surface of the tire. Use of studded tires outside of this period may result in a fine.

If you are using studded tires, you should have them on all four wheels for even traction. If using studded tires on the front of the vehicle they must be used on the back of the vehicle as well.

British Columbia Frost Laws

The British Columbia Ministry of Transportation and Infrastructure maintains an updated database that posts notices of seasonal load restrictions by region. Depending on the region, weight restrictions may already be in place, while others are scheduled to take place imminently. The ministry also offers email notification of load restrictions via subscription service.

The link below includes an interactive map with links to 28 regions. Each region posts its current road conditions and any weight restrictions imposed. The current map indicates restrictions from "no weight restriction" to "50%" of rated axle weights. It also includes access to recently update Load Restrictions and Road Reports.

British Columbia Annual Permits

No published information on Annual permits, only on specific commodity term permits.

British Columbia Road Conditions

Cone Zone Campaign

The Cone Zone campaign runs from May to August each year to reduce the number of deaths and injuries of roadside workers by increasing awareness of the vulnerability of these workers and encouraging drivers to practice safe driving behavior in the cone zone.

  1. Slow down and drive with extreme care near a Cone Zone.
  2. Stay alert and minimize distractions.

Slow Down

  • Plan your route and allow extra travel time.
  • Expect the unexpected and don’t tailgate.
  • Slow down to posted speed limits and pay attention.
  • Allow extra space between your vehicle and the one in front of you.

Keep your eyes (and ears) on the road

  • Never use a cell phone or text while driving.
  • Follow sign and flag directions.
  • Get to know the work zone signs.

Show respect for roadside workers

  • Slow down even if you don’t see anyone working. Hazards such as traffic shifts or lane reductions may appear suddenly.

British Columbia Manufactured Houses and Mobile homes

Mobile home and Manufactured housing travel requirements: These requirements are based on holiday and travel restrictions, width, length, weight limitations, and quite a few other facts to help make your decisions.
