What must a motorcycle rider do if they encounter gravel on the road?

When a motorcycle rider encounters gravel on the road, the best course of action is to slow down and maintain a steady course. This approach is crucial because gravel can cause loss of traction, making it difficult for the motorcycle to maintain control. By slowing down, the rider minimizes the risk of skidding or losing control over the motorcycle. Additionally, maintaining a steady course helps the motorcycle to navigate the surface more smoothly, reducing the chance of an accident.

The rider should avoid rapid acceleration, which can lead to sudden loss of traction and increase the likelihood of a skid. Quickly swerving to evade gravel may also lead to loss of control or an unexpected spill, especially if the gravel is spread over a large area. Ignoring gravel is not a safe option either, as it can easily lead to dangerous riding conditions that could result in a crash. Therefore, slowing down and keeping a steady course is the safest and most effective response when encountering gravel on the road.
