Explanation
Roads are most slippery when it first starts to rain after a dry spell, as oil and dust build up on the surface and haven't yet been washed away. This effect is worsened in hot weather, when heat draws more oil to the surface. When rain begins, turn on your windshield wipers and low-beam headlights, slow down, increase your following distance, and avoid sudden braking. Stay alert and be ready to respond if your tires begin to skid on the slick surface.
