How to Prepare Your Commercial Trucks for the Cold Season
How to Prepare Your Commercial Trucks for the Cold Season
Posted on November 21, 2025
When winter hits Ontario, commercial drivers know it’s not just about staying warm, it’s about keeping their trucks safe, reliable, and road-ready. At Metro Freightliner in Strathroy, ON, we understand how challenging the cold months can be for fleets and owner-operators. Between icy roads, heavy snow, and freezing temperatures, your trucks face serious stress. Proper preparation before winter arrives can make all the difference in performance, safety, and uptime.
Why Winter Preparation Matters
Cold weather can put enormous strain on every part of a commercial truck, from the battery to the braking system. Regular inspections and preventative maintenance are key to avoiding breakdowns, delays, and costly repairs. By taking the time to prepare your truck now, you’ll not only protect your investment but also keep your drivers and cargo safe on the road.
Conduct a Thorough Winter Inspection
Before the first snowfall, schedule a full inspection of your fleet. Start by checking your brakes, tires, and lights, the three areas most affected by cold weather. Brake lines and pads can stiffen in freezing temperatures, so ensuring they’re in peak condition is vital. Tires should have proper tread depth (at least 6/32 inches) and correct air pressure, which often drops as temperatures fall. Also, inspect all exterior lights to make sure they’re functioning and visible in poor weather.
Fluids are another critical area. Make sure to use the right engine oil for cold conditions and check your antifreeze mixture, a 50/50 mix of coolant and water is typically ideal. Top up your windshield washer fluid with a winter-rated formula that won’t freeze in low temperatures.
Battery and Electrical System Care
Few things are more frustrating than a dead battery on a cold morning. Cold weather reduces battery efficiency, so testing your battery’s charge before winter is essential. Clean any corrosion on terminals and make sure your alternator is functioning properly. A healthy electrical system ensures your lights, defrosters, and heating systems all perform when you need them most.
Equip for Traction and Control
Ontario’s winter roads can be unpredictable. Equip your trucks with winter tires designed to handle snow and ice, they’ll provide better grip and shorter stopping distances than standard tires. For routes through particularly icy or hilly regions, carry tire chains for added traction. Drivers should know how to properly install and remove chains and should practice doing so before they’re needed in an emergency.
Keep Drivers Winter-Ready
Even the most well-maintained truck can’t perform safely without a well-prepared driver. Provide training sessions on winter driving techniques such as gentle acceleration, maintaining longer following distances, and avoiding sudden braking. Drivers should also know how to identify black ice, that thin, nearly invisible layer that can form on bridges, shaded roads, and early mornings. Encourage drivers to monitor weather forecasts and road conditions before each trip. Open communication between drivers and dispatch is key to planning safe routes and avoiding hazardous conditions.
Prevent Rust and Corrosion
Salt and moisture are harsh on commercial trucks, especially those that spend long hours on snowy highways. Applying an anti-corrosion spray to exposed metal surfaces, undercarriages, and brake lines can protect against rust. Regularly washing your truck, including the underbody, helps remove road salt buildup that leads to corrosion over time.
Maintain Proper Fluid Levels
Checking all fluid levels should become routine throughout the winter. Oil, coolant, brake fluid, and even fuel can behave differently in freezing temperatures. Consider using winter-grade diesel to prevent fuel gelling, and always keep fuel tanks at least half full to reduce condensation buildup.
