What must you reckon with when it starts raining after a long period of dry weather?

Your answer is correct because when it starts raining after a long dry period, two main hazards occur. First, oil and dirt accumulated on the dry road surface mix with the rainwater, creating a slippery, greasy film that can reduce tire grip. Second, as you switch on the windscreen wipers, visibility can be temporarily poor due to water streaks and dirt being wiped across the glass. It is important to be cautious, reduce speed, and increase following distance. The idea that braking distances become shorter in such conditions is false; in fact, braking distances often increase because of reduced traction. Understanding these effects helps you drive safely under changing weather conditions.
