What is required of drivers when driving in adverse weather conditions?

Answer: C — Drive at a reduced speed

In adverse weather conditions, such as rain, snow, fog, or ice, driving at a reduced speed is essential for ensuring safety. Reduced speed allows drivers more time to react to unexpected situations that may arise, such as sudden stops from other vehicles, obstacles on the road, or slippery surfaces. The ability to control the vehicle effectively decreases significantly in poor weather conditions, making it crucial to adjust speed accordingly. Maintaining a safe following distance is also much easier when driving at reduced speeds, which can help mitigate the risk of collisions. Adverse weather often decreases visibility and traction, so being more cautious on the road by slowing down is a vital practice. In contrast, adhering to the regular speed limit in such conditions may lead to unsafe driving practices, as the road conditions may not permit it. Additionally, using high beams can create glare that may hinder visibility rather than improve it, especially in foggy conditions. Therefore, recognizing the importance of adjusting speed based on the weather is integral to safe driving practices.
