Rain

Rain makes road surfaces slippery, especially as the first drops fall. With more rain, tires make less contact with the road. If there is too much water or if you are going too fast, your tires may ride on top of the water, like water skis. This is called hydroplaning. When this happens, control becomes very difficult. Make sure you have good tires with deep tread, and slow down when the road is wet.

Rain also reduces visibility. Drive slowly enough to be able to stop within the distance you can see. Make sure your windshield wipers are in good condition. If your wiper blades do not clean the windshield without streaking, replace them.

In rain, try to drive on clear sections of road. Look ahead and plan your movements. Smooth steering, braking and accelerating will reduce the chance of skids. Leave more space between you and the vehicle ahead in case you have to stop. This will also help you to avoid spray from the vehicle ahead that can make it even harder to see.

Stay out of puddles. A puddle can hide a large pothole that could damage your vehicle or its suspension, or flatten a tire. The spray of water could splash nearby pedestrians or drown your engine, causing it to stall. Water can also make your brakes less effective.
