Question: 1 / 400

Why should you slow down when driving on wet roads?

Most people don't know how to drive in the rain.

Your tires lose traction on wet roads, especially where there is oil buildup on the paved surface.

Slowing down when driving on wet roads is crucial primarily because wet conditions significantly reduce the traction between your tires and the road surface. Water creates a thin layer between the tires and the pavement, making it harder for the tires to grip the road. This loss of traction can lead to skidding or hydroplaning, particularly in areas where oil and water mix, which can be more slippery.

When driving at high speeds on wet roads, the likelihood of losing control increases drastically, making it essential to adjust your speed accordingly to maintain control of the vehicle and ensure your safety as well as that of others on the road. Recognizing the dynamics of tire performance in wet conditions, such as the decreased friction and increased stopping distances, underscores the importance of driving more cautiously when the pavement is wet.
