What should you do when driving on wet or slippery roads?

When driving on wet or slippery roads, using low gear is the most suitable option because it allows for better control of the vehicle. Low gear helps to maintain traction and provides more power to the wheels, which is essential when navigating on surfaces that may cause your vehicle to skid or lose grip. By keeping the engine revs higher in low gear, the wheels can manage slower speeds more effectively, reducing the likelihood of hydroplaning.

In contrast, driving in high gear can lead to loss of control, as it makes the vehicle more prone to skidding due to insufficient power and braking force. Driving with headlights off is not safe and is not recommended, especially in wet or low-visibility conditions where it is crucial to be seen by other drivers. Accelerating quickly on slippery surfaces is risky, as it can easily lead to loss of control and spinouts. Thus, using low gear is the most appropriate action to take for safety when faced with wet or slippery road conditions.
