What must you do if you're involved in a collision?
Stop. If there's injury or damage and you don't exchange details at the scene, report it to the police as soon as practicable — at most within 24 hours.
Should you remove an injured motorcyclist's helmet?
Not unless it's essential to restore breathing — removing it can make head and neck injuries worse.
