What action should a rider take when encountering a slick road surface?

Answer: B — Reduce speed and increase following distance

When encountering a slick road surface, the most prudent action for a rider is to reduce speed and increase following distance. Slick roads, often caused by rain, oil, or other substances, significantly decrease traction, making it easier for a motorcycle to skid or lose control. Slowing down allows the rider to maintain better stability and control over the motorcycle, which is crucial in such conditions. Increasing the following distance gives the rider more time to react to any sudden changes in traffic or road conditions. This extra space can be vital if a car in front suddenly stops or if the rider needs to maneuver to avoid a hazard. Overall, a cautious approach is essential on slick surfaces to ensure safety.
