What should drivers be especially aware of in fog or rain?

Drivers should be especially aware of reduced visibility and slippery roads during fog or rain due to the significant impact these conditions have on safety. Fog can create a thick barrier that limits how far a driver can see ahead, making it difficult to judge distances, identify other vehicles, and respond effectively to road signs and signals. Similarly, rain can lead to slick surfaces due to water mixing with oil and debris on the road, increasing the risk of hydroplaning and loss of traction.

Understanding these hazards allows drivers to adjust their behavior appropriately, such as reducing speed, increasing following distances, and using headlights to improve visibility. These adjustments are essential for maintaining control of the vehicle and preventing accidents under such challenging weather conditions.
