A serious hazard for drivers in severe frost is an unreliable battery, missing backup fuses, and heavy snow accumulating on wheel arches, along with using inappropriate diesel fuel. An automotive expert noted this risk in a recent safety briefing.
Old or dead batteries can stall a vehicle even after a quick warm-up, and in very cold conditions the battery may struggle to provide enough power for a restart after a pause on the road. In freezing weather, a battery often cannot recharge effectively and may only supply a brief burst of energy. The key takeaway is that warming the engine compartment helps the battery begin charging again, but short trips or extreme cold can make this step difficult to accomplish.
Another cold-weather issue is washer fluid freezing in the nozzles. This problem is common with isopropyl alcohol based antifreezes sold for winter use. Unlike methanol, isopropanol thickens when cold and fails to clear the windshield, which can create visibility hazards. Drivers should consider fluids formulated for very low temperatures and ensure proper nozzle function before setting off on frosty mornings.
Diesel-powered vehicles face a different challenge when winter conditions arrive. Using summer diesel during cold periods can be risky, as it can perform poorly in low temperatures. It is prudent for owners of diesel cars to refuel at reliable stations, including those frequented by heavy-duty vehicles, to avoid gelation and poor cold-start performance. Refueling at trusted locations reduces the chance of encountering suboptimal fuel that could hinder starting and running in freezing temperatures.
Snow packed around the wheel arches can interfere with precise maneuvering. In bitter cold, carrying spare fuses and keeping a small set in the cabin is sensible so a fuse can be replaced quickly if wipers stick to the windshield or other electrical components fail during a cold snap. Preparing a compact emergency kit becomes a practical precaution for winter drives.
Earlier reports described a roadside incident on a frosty stretch of highway where a couple found themselves stranded on a broken vehicle in forty-degree frost. Responders assisted after about ninety minutes, underscoring how winter conditions can turn a minor delay into a dangerous situation if vehicles are not properly prepared. This example highlights the importance of routine winter readiness, careful fuel choices, and timely battery and fluid maintenance for safe driving in severe cold.
