Car Door Opening
A driver or passenger opens a parked car door directly into a motorcyclist's path.
What is it
Dooring is when a parked car's door suddenly opens into a motorcyclist's path. The door becomes a wall you ride into. Even at low speed, it can knock you off the bike.
How it happens
A rider travels along a row of parked cars. A driver or passenger opens the door without checking the mirror or looking back. The rider either hits the door or swerves into other traffic.
How to reduce the risk
- Keep distance from parked cars — at least one door width (3-5 feet)
- Watch for signs: parking lights on, shadow movement inside, brake lights
- Slow down past rows of parked cars
- Never ride in the «door zone» — even if it seems more convenient
