Before starting a journey in bad weather, what maintenance step should a driver take?

Before starting a journey in bad weather, topping up the windscreen washer reservoir is crucial for maintaining visibility. In adverse weather conditions, like rain, snow, or fog, your windscreen can easily become dirty or obscured with grime, reducing visibility significantly. A well-filled reservoir ensures that you can use the windscreen wipers effectively, allowing you to clear the windshield of water, dirt, or any other debris that could hinder your view.

While other maintenance steps like checking tire pressure, inspecting lights and indicators, and filling the fuel tank are also important aspects of vehicle safety and performance, they do not directly address the immediate need for clear visibility in bad weather. Ensuring your windscreen washer fluid is topped up is a proactive measure that directly correlates with safety during travel in poor conditions.
