What safety precautions should I take when riding a mountain bike on the road?

When riding a mountain bike on the road, it is important to wear a helmet at all times to protect your head in case of a fall or accident. Additionally, make sure your bike is equipped with proper lights and reflectors to increase visibility to other road users, especially in low light conditions. Follow traffic rules and signals, ride in the same direction as traffic, and use hand signals to indicate your intentions to other drivers. Stay alert and aware of your surroundings, and always be prepared to brake or maneuver quickly if needed.
