Rain and wet roads can make driving dangerous. Here are a few things to consider when driving in the rain or on slick pavement:
Hydroplaning
If the road is wet enough and you are going fast enough, your vehicle may have little or no contact with the road surface and actually ride on the water. The best advice is SLOW DOWN when the road is wet.
The risk of hydroplaning increases as the depth of tire tread decreases, refer to "Tire Tread" in chapter 7.
