Explanation
Roads are the most slippery during the first rain after a dry spell. This is because during a dry period, oil and dust accumulate on the road surface. When rain finally arrives, it mixes with this residue, creating a slick and greasy surface. This reduces the friction between your tires and the road, compromising their grip. To stay safe, slow down and exercise caution at the first sign of rain after a dry spell.
