Weather-Related Crashes
There are almost six million vehicle crashes in the United States each year. One out of four crashes is weather-related. Learn how to drive safely on slick roads and how to handle a skid before taking your DMV written test. You should expect at least one or two questions about driving in adverse weather and on slippery roads.
If you live in a northern state with severe winter conditions, expect at least one question about winter driving.
The Most Important Safety Feature
Tires are the most critical safety feature when driving on slippery roads. The only contact your vehicle has with the road is through the tires.
Regular tires provide good traction up to 35 mph. When you drive faster, your tires may start hydroplaning—much like water skis. At 50 mph, your tires can lose all traction. Worn tires will lose traction at much lower speeds and are extremely dangerous on slippery roads.
The tread depth of your tires must be at least 2/32 of an inch, measured in two adjacent grooves. Check your tires regularly. You should also ensure they have the correct pressure, no bulges, no fabric showing, no bald areas, and no cuts.
Plan Your Drive
Avoid driving in heavy rain, if possible. Check weather reports and delay your trip if heavy rain or thunderstorms are approaching. Heavy rain often slows down traffic on major highways.
Slow Down and Adjust Your Following Distance
If you must drive on slippery roads, reduce your speed and increase your following distance. Your vehicle won’t be able to stop as quickly as it would on dry roads.
You should maintain a following distance of at least 4–5 seconds from the vehicle in front of you. Remember that slippery surfaces can be especially dangerous for motorcycles. If you are following a motorcycle, use extra caution.
Questions about speed and following distance on slippery roads are among the most common on DMV written tests in all states. Ensure you recognize and understand the road sign “Slippery When Wet“.
Use Caution at All Times
Be careful when turning. Slow down before entering any curve. If you go too fast in a curve, your tires may not grip the road surface and could cause a skid.
Start braking well in advance of a stop. You should also use your turn signals earlier. This helps other drivers understand what you plan to do, allowing them to adjust their speed or position.
Know How to Master a Skid
If your vehicle starts to skid, it’s easy to panic. Reading and talking about skids is often not enough for new drivers. If you can, practice in a safe area. Ask a local driving school for advice. It may cost a few dollars, but it could save your life one day.
The most important thing to remember about skids is to slow down. You can only regain traction by allowing your car to slow.
Remove your foot from the gas pedal instead of slamming on the brakes. When you regain traction, press the brake pedal firmly if you have anti-lock brakes. Otherwise, pump the brakes gently. Steer in the direction you want the car to go.
