Winter driving claims more commercial truck drivers' lives than any other road condition. Ice, snow, reduced visibility, and other vehicles' unpredictable behavior create a uniquely dangerous environment that demands a completely different driving approach. This guide covers the fundamentals every driver needs before the temperature drops.
The first rule of winter driving is simple: slow down. Posted speed limits are set for ideal conditions. In snow or ice, your stopping distance can increase by 10x. There is no timeline, no load, no dispatcher pressure worth your life or someone else's. Give yourself extra following distance — at least 8–10 seconds behind the vehicle ahead in slippery conditions.
Brake management is critical. On slippery surfaces, hard braking can cause a jackknife in seconds. Use engine braking on descents. Apply your service brakes smoothly and progressively. If you feel your trailer starting to push, ease off the brakes immediately. Practice recognizing the early signs of a slide before it becomes uncontrollable.
Pre-trip inspections take on extra importance in winter. Check your brakes for proper adjustment, inspect tires for adequate tread depth (minimum 4/32" on drives), and verify that all lights are working — visibility cuts both ways. Carry chains where required and know how to install them quickly in cold, wet conditions.
Know when to stop. This is perhaps the hardest lesson for experienced drivers who pride themselves on making their delivery. If conditions deteriorate beyond what you can safely handle, pull off the road. A delayed load is recoverable. A jackknifed truck blocking an interstate, an injury, or worse — are not. Chain control laws exist for a reason. Respect them.
