1. Changes in temperature impact tire pressure.  Check your tire’s air pressure at least once a month and keep them inflated to manufacturer’s recomendations (usually printed on the vehicle door placard or owner’s manual).
2. Check the tires tread depth. As rain falls, it mixes with grime and oil on the road creating slick conditions. Driving at a slower pace allows more of the tire’s tread to make contact with the road, which leads to better traction.
3. If your car skids, remember not to slam on the brakes. Apply firm, steady pressure to the brakes and steer the car in the direction of the skid.
4. It takes about three times longer to brake on wet roads than on dry roads. Since more distance is required to brake, it is important to not tailgate. Keep a little more than two car lengths between you and the vehicle in front of you.
5. Avoid using your brakes. Whenever possible, slow down by taking your foot off the accelerator.
6. Wet-weather driving demands gentle use of all the main controls – steering, clutch, brake and accelerator – and a larger allowance for errors and emergencies. Turn your headlights on, even in a light rain. All motorists should regularly check that their headlights, rear lights, brake lights and turn indicators are working properly.
7. Ninety percent of driving decisions are based on visual input alone. Heavy rain can overload wiper blades, allowing an almost continuous sheet of water to flow over the screen. Inspect your wiper blades and replace them if they are cracked, torn, cut or streaking.  When visibility is so limited that the edges of the road or other vehicles cannot be seen at a safe distance despite your wiper blades, it is time to safely pull over and wait for the rain to ease up. Keep your headlights on and turn on your hazard warning lights to alert other drivers.
8. Cloudy weather reduces visibility. Use extra caution when passing other vehicles.
9. If you have driven through standing water deep enough to get your brake shoes wet, apply the brakes lightly to dry them.
10. Don’t drive while fatigued.  Stop at least every couple of hours or every hundred miles to rest.
11. Before taking a long trip, ensure your car is properly tuned.
