Why should you check your vehicle before the start of the cold weather period?

Your answer is correct. Before cold weather begins, it is important to check your vehicle because low temperatures can cause several issues: the engine’s cooling water system might freeze if it lacks sufficient antifreeze, the battery can lose capacity or fail completely in cold weather, and the windscreen washer system can also freeze if it doesn't have winter-grade fluid. Checking these systems helps prevent breakdowns and ensures safe driving in winter conditions. Always make sure your vehicle is prepared for colder temperatures to avoid problems on the road.
