* Exercise extreme caution after a long dry spell. During a dry period, engine oil and grease build up on the road over time. When mixed with water from a new rainfall, the road becomes extremely slick. Continued rainfall will eventually wash away the oil, but the first few hours can be the most dangerous.
* Allow for more travel time. You should plan to drive at a slower pace than normal when the roads are wet. Keep in mind that traffic is likely to be moving slower as well. There's also the possibility that your preplanned route may be flooded or jammed. Whatever the case, rushing equals higher risk.
* Brake earlier and with less force than you would normally. Not only does this increase the stopping distance between you and the car in front of you, it also lets the driver behind you know that you're slowing down. Also, be more meticulous about using turn signals, so that other drivers know your intentions, and take turns and curves with less speed than you would in dry conditions.
* Most of America's roads are crowned in the middle, which means that the water will run off to the sides. If possible, stay toward the middle of the road to avoid deep standing puddles.
* Don't use cruise control. If you hydroplane, there's the chance your car could actually accelerate. Cruise control also allows drivers to be less vigilant and to take their foot away from the pedals — not a great idea when reaction time is so important. more
