Winter can surprise not only road maintenance crews but also carriers. Frost, snowfall, black ice, or sudden temperature drops directly impact fleet operations. That’s why October is the right time to prepare your fleet for winter. Below are 10 key areas worth checking to minimize the risk of breakdowns, delays, and unnecessary costs.
Tires and Pressure
Checking the condition of tires is essential. In winter, grip is crucial, so pay attention to tread depth (recommended minimum 4 mm for winter tires), the absence of cracks or damage, and correct pressure (lower temperatures = lower pressure). Plan tire changes in advance and store them properly.
Battery
Low temperatures significantly reduce battery performance. Before winter, check voltage and capacity, clean corroded terminals, and verify the alternator’s charging status. A weak battery is one of the most common causes of winter breakdowns.
Braking System
Effective braking in poor weather is vital. Check the condition of brake pads and discs, the air system’s tightness, the air dryer’s operation, and the frost resistance of brake lines.
Lighting and Electronics
Shorter days and worse visibility mean lighting is used more frequently. Test all bulbs, replace any that are burnt out, and clean the lamp lenses. Also check parking sensors, reverse cameras, and other driver assistance systems.
Fluids
Winter demands proper operating fluids. Use freeze-resistant washer fluid and coolant rated for at least -35°C. Check engine oil condition and viscosity, and replace it as recommended by the manufacturer.
Heating Systems
A functioning heater is not just about comfort but also safety. Inspect the cabin heater, auxiliary heating systems, fans, and heating ducts for leaks. Poor heating can lead to freezing windows and reduced visibility.
Emergency Equipment
Every vehicle should be equipped with winter emergency gear: snow chains (where required), jumper cables, flashlight, thermal blanket, snow shovel, and de-icers for locks and windows. These tools can make the difference in a critical situation.
Bodywork and Seals
Winter use promotes rust and leaks. Protect exposed body parts and treat door/window seals with silicone. Ensure locks and windows are sealed tight to prevent moisture from getting inside.
GPS and Monitoring Systems
A working GPS system means safer and more efficient route planning, especially during snowstorms, traffic jams, or breakdowns. Update software and verify the performance of mobile tracking apps.
Driver Training
Vehicle readiness is one thing, but driver awareness is equally important. Remind them of winter driving rules, train them in auxiliary heating systems, and review emergency procedures in case of a vehicle getting stuck.
How to prepare your fleet for winter?
Winter doesn’t have to mean breakdowns and downtime. Preparing your fleet in advance increases safety, reduces costs, and prevents complaints. The key lies in consistent technical inspections, clear team communication, and understanding that even minor oversights can lead to major winter issues. October is the best time to prevent rather than react.
