What should you do when driving on a wet road?

Answer: D — Allow for more stopping distance

Since the road is wet, it becomes more slippery and you may need to stop suddenly. Increasing your speed (A) and driving twice the speed limit (C) can be dangerous as it can lead to loss of control of the vehicle and cause accidents. Turning off your headlights (B) can also increase the risk of accidents as other drivers may not be able to see your vehicle. Therefore, allowing for more stopping distance (D) is the safest option to avoid accidents and maintain control over your vehicle.
