when are the roads most slippery during before or after a rain storm?

Roads are their most slippery at the beginning (first few minutes) of a rainstorm. When the road first gets wet, oil rises to the surface and creates a greasy surface.

Rain has been the cause of thousands of car accidents year in and year out, and rain is especially dangerous in dry weather states like California.

According to AAA.com, wet pavement contributes to nearly 1.2 million traffic crashes each year. Below are some tips you’ll want to follow the next time you’re caught driving in the rain (courtesy of SeriousAccidents.com):

1. Drive slower. This is an obvious but important tip, as it allows for better reaction times. Rainwater causes grease and oil built up on the road to surface and tires traction suffers as a result. If you drive slower, your tire traction will improve and you will also have more time to brake.

2. Keep your eyes on the car ahead of you. In the rain, it’s often hard to see very far ahead of you. On a clear sunny day, you can see the traffic situation a couple hundred feet down the road and react accordingly. On a rainy day, it helps to watch for the reaction of the driver ahead of you.

3. Do not brake suddenly. Sudden braking may cause a skid. Since the roads are slippery, stopping the wheels too quickly may cause them to lose all traction with the road, and an imminent car accident becomes a distinct possibility.

4. Correctly defog your windows. The windows on your car might fog, further limiting you visibility. To defog, keep your air conditioning blowing at both your windshield and your back window.

5. Avoid standing or flood water. Most roads are built with the middle of the road higher than the sides, so try to stay near the middle of the road where it would be less likely to have a buildup of rainwater. No automobiles can drive through the ocean floor and have firm tire grip in deep water like the sport utility vehicles presented in commercials, so stay away from pools of water.
