What should you avoid when driving in heavy rain?

Using cruise control in heavy rain is advised against because it can lead to reduced driver control. When the road is wet, the risk of hydroplaning increases, which occurs when a vehicle's tires lose traction and glide on the water surface instead of making proper contact with the road. If a driver is using cruise control, they may not respond as quickly to changing conditions, such as needing to slow down or adjust their driving due to water accumulation on the road.

In contrast, driving with headlights on enhances visibility, which is crucial in heavy rain. Maintaining a longer following distance allows for more reaction time, helping to prevent rear-end collisions. Staying to the right side of the road can be beneficial for safety as it often keeps you away from faster-moving traffic. Thus, while options related to proper visibility and safe following distances are important for overall safety, using cruise control in wet conditions can significantly compromise a driver's ability to react appropriately to the road and weather conditions.
