1 Wait Until the Weather Improves if Possible If you feel uncomfortable driving in the rain and can postpone your trip or commute, wait until the weather improves before driving. There is no reason to put yourself in danger if driving in wet conditions is not necessary.
2 Double Check Your Car’s Equipment Make sure that your car’s equipment is in working order before encountering rainy weather. Check your headlights, tail lights, and windshield wipers to make sure that they will work efficiently when they are needed. Also check the tread of your vehicle’s tires. Balding tires can severely reduce traction on wet roadways. Most states require tires to have a tread depth of at least 2/32″ to stay on the road
3 Slow Down Not only should you adhere to the posted speed limit when driving in wet weather conditions, you should drive considerably slower than you normally would. Wet roads are very dangerous. Your vehicle’s reaction time is much slower when it is raining. Reduced speed is imperative in rainy weather.
4 Turn On Your Headlights Most states require drivers to turn on their vehicles’ lights while driving in rain. Even if it is only misting, turning on your vehicle’s headlights will increase both your own visibility and other drivers’ ability to see your car on the road.
5 Use Your Windshield Wipers While this may seem like common sense, some people forget to turn on their windshield wipers in light rain. Most cars’ windshield wiper speed is adjustable to clear moisture from the glass in a light mist or in a heavy downpour. There are also several products available that can be sprayed or wiped onto the glass and claim to defer the collection of rainwater. Your wipers should be replaced if you can hear a scraping noise or see some streaking from the blades
6 Maintain a Safe Distance Between Cars Keep a greater distance between your vehicle and the car in front of you. Stopping your vehicle will be more difficult when driving in the rain. Maintain a distance of several car lengths between your car and other vehicles.
7 Avoid Heavy Braking Try to slow your vehicle by taking your foot off the accelerator earlier than you normally would in preparation to slow down or stop. Don’t use cruise control so your attention on using both the gas and brake are in tune.
8 Watch Out For Standing Water Driving through standing water can cause hydroplaning to occur. Which is when you lose traction and skid across the surface of the road. To avoid hydroplaning, drive around places where water has collected by changing lanes or safely steering around such areas. Six inches of water can cause loss of control on the road
9 Let Off The Gas When Hydroplaning Hydroplaning is one of the most common car accidents in the rain because drivers can lose control. If your car hydroplanes, calmly take your foot off the accelerator and steer in the direction that the front of your car needs to go. Avoid making sudden turns or slamming on your brakes.
10 Ventilate Your Car Rain causes humidity levels to increase. You may find that your vehicle’s windows become foggy when you operate your vehicle while it is raining. Most cars’ ventilation systems include a function that will work to reduce this type of fog that develops on the interior of your windows and windshield. It may be necessary to pull over if you are no longer able to see through your windows. Lower the temperature inside your car quickly by cracking a window if your vent system doesn’t help Staying safe while driving in the rain is simple if you make a conscious effort to employ these safety precautions. Remember that reducing your speed and turning on your lights are two of the simplest and most effective ways of reducing the chances of an accident caused by wet weather.
