# Explanation
Riding a motorcycle in heavy rain significantly reduces tire grip on the road and decreases visibility. For this reason, it is mandatory to **reduce speed considerably** and be prepared to stop if conditions become too dangerous. You should never ride close behind the vehicle in front, as this increases the risk of collision.
