Frequently Asked Questions
General
What is a long combination vehicle (LCV)?
In Canada, any combination of vehicles over 25 metres overall length is considered to be an LCV. BC LCVs are made up of a tractor pulling two full-length semi-trailers up to 40 metres overall length but do not exceed the normal weight restrictions. In BC, LCV are made up of Rocky Mountain Doubles and Turnpike doubles

Why is BC allowing LCVs on our highways?
LCVs are a win-win-win. They are good for the economy, good for the environment and improve highway safety. They can move goods at a lower cost and with fewer greenhouse gas emissions than single-trailer trucks and, under carefully controlled conditions, more safely.
Once in fuller use on BC’s highways, LCVs could save shippers – and Consumers millions a year:
- Fuel consumption could be reduced by several million litres a year
- Greenhouse gas emissions could be reduced by several thousand tonnes a year.
In addition, allowing LCVs will enable shippers to move goods more efficiently between BC, Alberta and Saskatchewan and eastern Canada.
What is BC proposing with respect to long combination vehicles?
LCVs will be restricted to predetermined highways and approved access points close to highway ramps. They will also be restricted from operating in or through urban areas during rush hours, and across the province at the start and end of long weekends
Drivers must have extensive experience driving tractor-trailers, a proven safety record, and will take special training and road testing to ensure safe operation.
Would BC simply allow unrestricted operations of LCVs?
No. LCVs operate under carefully controlled conditions in every province that allows them, even after decades with excellent safety records. The BC government is not considering allowing unrestricted LCV operations.
Will LCVs replace all the regular trucks in BC?
No. The majority of tractor-trailer trips will remain as they are. A very limited number of LCVs will be allowed, with a gradual increase anticipated in future years to ensure public safety and smooth integration into BC trucking operations.
LCV Routes
Where will LCVs be allowed to operate?
LCVs may only operate on predetermined highway routes and to and from terminals close to highway ramps that have been approved by MoTI. All off-highway routes require an engineering and safety assessment as well as municipal consent. LCV designated routes.
Where can I find the operating rules and program details for LCVs in BC?
Operating rules and program details are contained in a document titled, Conditions Governing the Operation of Long Combination Vehicles in British Columbia – forms T-59, T-59A. They outline the program principles, the driver and carrier qualifications, route criteria, special equipment and operating restrictions.
LCV Equipment
What is the maximum allowable weight for an LCV?
The allowable gross weight of any LCV combination must not exceed 63,500 kg. This is the same maximum weight as for other tractor-trailers, so LCVs will be no heavier than tractor-trailers currently operating on our highways. Maximum tire, axle and gross weights for the different types of trailer combinations are specified in the permit conditions. The braking ability of LCVs has been carefully reviewed to ensure optimal safety.
Do LCVs require any special equipment?
Yes, LCVs require a set of equipment upgrades to make them among the safest tractor-trailers on BC highways.
Special equipment required for LCVs in BC includes;
Truck Tractor:
- Must be manufactured and equipped in compliance with the Canada Motor Vehicle Safety Act standards (CMVSS) for at the time of manufacture.
- Engine Retarder or Driveline Retarder (hydraulic type) must be equipped and fully functional with minimum rated retardation horsepower capacity equal to or exceeding 75% of rated engine nameplate horsepower.
- All truck trailers must feature a maximum gross weight to power ratio of 150 kg per one horsepower.
- The power unit must be adequately geared and powered to be able to maintain speeds at posted speed limits on level ground.
- Must be equipped with an anti-lock braking (ABS) system.
- Must be equipped with:
- an electronic log book recorder (elog), and
- an onboard recording device or computer which measures the LCV’s speed and time
Trailers:
- Must be manufactured and equipped in compliance with the Canada Motor Vehicle Safety Act standards (CMVSS) at the date of manufacture.
- All trailers exceeding 8.6m in length must be equipped with lateral amber lights visible on each side to cross traffic and those lights must be spaced at intervals of approximately one-third of the total overall length of the trailer combination.
Will the LCVs be allowed to operate like other tractor trailers?
LCVs will have specific and detailed operating restrictions that must be followed. The LCV permit outlines where and when participants may operate these vehicles.
LCVs:
- Only consolidated small shipments may be hauled, excluding dangerous goods.
- Drivers must load and couple vehicles to ensure the LCV combination, when ravelling in a straight line on level, smooth and paved surfaces, will follow the path of the towing vehicle without shifting, swerving, or swaying more than 10cm side to side from the path of the towing vehicle.
- Drivers must carry their LCV Driver’s Certificate when operating an LCV.
- Unless otherwise authorized in writing by MoT, the Permittee must ensure that LCV are only operated when the elog and onboard recording device are activated and functioning.
- Headlights must be on at all times while operating the LCV.
- Maximum speed shall be the lesser of 100 km/h or the posted speed limit.
- Unless directed by an authorized MoT employee or a peace officer:
- LCVs may only be operated on routing described in form T-59A.
- LCVs may only use highway turn-a-rounds or park trailers on the highway under demonstrated emergency situations; and
- Any breakup or makeup of LCVs must be done off public roadways on private property.
LCVs operating in the Peace District may use the former Pouce Coupe Inspection Station location as a turnaround (breaking up of the combination may be required).
- LCV drivers must travel in the rightmost lane at all times, except to pass. Passing is allowed under the following conditions:
- Highways with two lanes in one direction: LCVs may only pass vehicles travelling less than 80km per hour, when onlevel ground.
- Highways with three lanes in one direction: LCVs may travel in the middle lane to pass slow moving vehicles.
- Highways in the Peace River District: LCVs may pass when it is safe to do so.
- Drivers must avoid crossing opposing lanes of traffic unless absolutely necessary.
- No convoying with another LCV is allowed within a distance of 1 km.
- Except in urban areas, drivers must follow other commercial vehicles at a minimum distance of 500 metres.
Safety
Aren’t LCVs more dangerous than regular single-trailer trucks?
No – in fact they are safer. LCVs have been on the road in Western Canada, Ontario, Quebec, and more than 20 American states for a number of decades. They have an excellent safety record, with fewer collisions reported than single-trailer trucks. LCVs also reduce the total number of trucks on the road, since each LCV carries as much freight as two single trailer trucks.
Adverse Weather:
- LCVs must not operate during adverse weather, or when driving conditions impede the driver’s ability to operate in a safe manner or prevent the driver from driving with reasonable consideration for the safety of persons using the highway. This includes conditions where:
- Visibility is obscured to less than 300 m
- There is snow present on the highway which affects the traction of the LCV.
- Vehicles must not be dispatched when adverse conditions are known to be present on the route. The Permittee is required to make a reasonable effort to determine the driving conditions on the route prior to each trip, and must be able to provide documentation of having done so upon request.
- Drivers encountering adverse conditions must stop at the next safe location (or as directed by an authorized MoT employee or a peace officer) and wait for conditions to improve.
If LCVs are carrying twice as much cargo, won’t they be slower to stop, and therefore more dangerous?
LCVs are suited to light, bulky freight as their maximum allowable weight is no greater than other tractor-trailers currently in operation. As LCVs are no heavier than current tractor-trailers, generally have more axles and tires to grip the road and are equipped with enhanced braking systems – their stopping ability is generally superior to other tractor-trailers.
Environmental Benefits
Are there environmental benefits to LCVs?
Yes. Greenhouse gas emissions are directly linked to the amount of fuel that is consumed. Each LCV uses about one-third less fuel than two tractor-trailers that would carry the same amount of freight. That means a third fewer greenhouse gas emissions for each LCV on the road.
LCVs will provide a meaningful contribution toward these reductions.
Infrastructure Impacts
If LCVs are carrying twice as much freight, won’t they do more damage to roads and bridges?
No. The maximum weight for LCVs will be the same as for other tractor trailers
Currently operating on our highways. LCVs actually have slightly less weight per axle and less impact on roads and bridges than the two single tractor-trailers they replace.
