Rain and wet roads can reduce vehicle traction and affect your ability to stop and accelerate.
Always drive slower in these types of driving conditions and avoid driving through large puddles and deep-standing or flowing water.
Warning
Wet brakes can cause crashes.
They might not work as well in a quick stop and could cause pulling to one side. You could lose control of the vehicle.
After driving through a large puddle of water or a car/vehicle wash, lightly apply the brake pedal until the brakes work normally.
Flowing or rushing water creates strong forces. Driving through flowing water could cause the vehicle to be carried away. If this happens, you and other vehicle occupants could drown. Do not ignore police warnings and be very cautious about trying to drive through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can build up under the vehicle's tires so they actually ride on the water. This can happen if the road is wet enough and you are going fast enough. When the vehicle is hydroplaning, it has little or no contact with the road.
There is no hard and fast rule about hydroplaning. The best advice is to slow down when the road is wet.
