Idaho Written Driver's License Practice Test

How can you reduce the chances of hydroplaning when the roads are wet?

1. Increase your speed

2. Drive with your headlights on

3. Reduce speed and stop from further away

4. Avoid driving on wet roads

The correct answer is: Reduce speed and stop from further away

Reducing your speed is the most effective way to decrease the chances of hydroplaning on wet roads. When you reduce your speed, your tires have a better chance of maintaining contact with the road surface rather than riding on top of the water. This is crucial because hydroplaning occurs when a layer of water builds up between your tires and the road, causing loss of traction and control. By driving more slowly, you'll allow your tires to push away some of the water, thereby enhancing grip and stability. It also allows for more reaction time when you need to stop or steer, which is especially important in adverse weather conditions. Stopping from further away complements this strategy because it increases your reaction time and helps you avoid sudden maneuvers that could increase the likelihood of hydroplaning. Driving with your headlights on is a good safety practice, especially in low-visibility conditions, but it does not directly affect the risk of hydroplaning. Additionally, while avoiding wet roads can reduce the risk of hydroplaning altogether, it is not always practical or possible. Thus, reducing your speed is the most reliable option for mitigating this risk when driving on wet surfaces.
