When encountering rain grooves or bridge gratings, what is the best action to take?

When encountering rain grooves or bridge gratings, maintaining a steady speed and riding straight across is the optimal choice. This approach helps to ensure stability and control while navigating these potentially slippery surfaces. Panic or sudden braking can lead to loss of traction and increased risk of skidding, making the situation more dangerous. Similarly, accelerating is not advisable as it may result in losing control, especially on surfaces where traction is compromised. Weaving to avoid grooves can lead to unpredictable movements and may also cause a loss of balance. Therefore, the best strategy is to remain calm, keep your speed consistent, and travel directly across the grooves or grating, which allows for a safe and controlled maneuver.
