Running freight through BC and Alberta in winter is not simply a matter of putting winter tires on and hoping for the best. The Coquihalla, Rogers Pass, and Kicking Horse Canyon are among the most technically demanding highway sections in North America during winter months. A fully loaded 40-tonne FTL unit on a 7 percent grade in a freezing rain event is a completely different operating environment than a summer highway haul.
Carriers who operate safely in these conditions do so because of procedures, not luck. This article outlines the protocols Keylink drivers follow on winter mountain freight corridors, and what every fleet should have in place before winter conditions arrive.
Winter Pre-Trip Inspection Checklist
Every trip starts before the engine turns over. In winter conditions, a thorough pre-trip inspection is not a formality. It is the difference between a clean run and a breakdown on a mountain highway in a snowstorm. Transport Canada requires commercial drivers to complete pre-trip inspections under the National Safety Code, and in winter those requirements carry additional operational weight.
Mountain Pass and Chain Control Procedures
Chain controls on the Coquihalla and Highway 1 through the Rockies are enforced conditions, not suggestions. Driving through a chain control without chains installed results in significant fines, potential licence suspensions, and, far more seriously, puts other drivers at risk. Every Keylink driver is trained on chain installation before operating on mountain corridors in winter.
Procedure when a chain control is posted: pull off at the designated chain-up area before the control, install chains on drive axles as required, confirm chains are properly secured and not dragging, then proceed through the controlled section at reduced speed. Once past the control zone, remove chains at the designated chain-off area to prevent road surface damage and chain wear.
"A chain control is not a suggestion. A carrier who sends a driver through without chains is not saving time. They are gambling with their driver's safety and their operating authority."
On downhill grades, drivers should be in the correct gear before beginning the descent. Do not attempt to downshift on a steep grade when the vehicle is already moving at speed. Retarder and engine brake usage should be planned in advance based on grade severity and load weight. On a loaded FTL unit, proper engine brake management is essential for maintaining controlled speed without overheating brakes.
Weather Monitoring and Go/No-Go Decisions
Not every winter driving situation is a go. Carriers need a clear decision-making framework for when conditions are too dangerous to proceed. That framework starts with real-time weather monitoring, not a check of the forecast the night before.
Dispatch should monitor road condition reports from Drive BC for provincial highways and Canadian Trucking Alliance alerts for corridor-level advisories. When conditions deteriorate mid-route, drivers need explicit authorization to stop and wait without pressure to push through. Carriers who pressure drivers to drive through unsafe conditions face not only the immediate safety risk but substantial liability exposure if an incident occurs.
The go/no-go decision should be made jointly between dispatch and the driver, with the driver having the final authority to refuse a run that they judge unsafe. This is not optional. Under Transport Canada regulations, drivers cannot be penalized for refusing to operate in conditions they judge to be unsafe.
Speed, Space, and Braking on Slick Roads
Posted speed limits on BC and Alberta highways assume normal driving conditions. In winter, those limits do not reflect safe operating speeds for a loaded FTL unit. A fully loaded B-train at 90 km/h in icy conditions requires dramatically more stopping distance than the same vehicle in summer. Drivers need to internalize this and adjust speed and following distance accordingly, not because an app tells them to, but because they understand the physics of their vehicle in those conditions.
General winter guidelines for mountain freight operations: reduce speed by 20 to 40 percent compared to summer conditions on the same grade, increase following distance to a minimum of 6 to 8 seconds, avoid sudden steering inputs on icy surfaces, and use engine braking smoothly and progressively rather than in sharp bursts that can induce trailer swing.
Emergency Protocol When Things Go Wrong
Even the most prepared drivers encounter situations that require emergency response: a tire blowout on a mountain grade, a slide on black ice, or a vehicle breakdown in sub-zero temperatures. Having a clear protocol before these situations occur is what separates a recoverable incident from a disaster.
At Keylink, drivers carry emergency kits including reflective triangles, flares, a first aid kit, extra warm clothing, and emergency rations for 24 hours. In the event of a breakdown, the first action is to get the vehicle safely off the travel lane and deploy warning devices at the required distances. The second is to contact dispatch immediately, report the location and situation, and wait for instructions.
Drivers should never attempt to repair a major mechanical failure on a mountain highway in winter conditions. The risk of a secondary collision while working on a vehicle on the shoulder is severe. Get off the road, get warm, and wait for professional assistance.
Keylink drivers are trained for mountain freight operations year-round. Our BC-Alberta lanes run reliably through winter because safety procedures are non-negotiable.
