What should a driver do if weather conditions deteriorate while driving?

Answer: B — Slow down and increase following distance

When conditions on the road worsen due to bad weather, it is crucial for a driver to adjust their driving behavior to maintain safety. Slowing down helps to reduce stopping distance and gives a driver more control over the vehicle, especially on slick or slippery surfaces. Increasing following distance provides a buffer zone, allowing for more time to respond to potential hazards, such as sudden stops by other vehicles or obstacles on the road. This approach reflects a key principle of defensive driving, where anticipation and preparation for unexpected changes are essential to prevent accidents. Adjusting speed and maintaining a safe distance not only enhances the driver's safety but also contributes to the safety of other road users. In contrast, maintaining speed may lead to a loss of control, and pulling over might not be safe or practical in all situations, especially if there is no designated stop area.
