What is the recommended action if you encounter a slippery surface while riding?

When encountering a slippery surface while riding, the recommended action is to stay in a straight line and reduce speed. This method is effective because maintaining your position reduces the likelihood of losing control. Abrupt changes in direction or sudden acceleration can destabilize the motorcycle and lead to a skid. By gradually slowing down while keeping the bike straight, you allow for better traction and handling, giving you more control and reducing the risk of accidents. Additionally, a straight-line approach helps keep your balance steady, minimizing the chances of a fall or a loss of control on the slick surface.
