Streetsblog SF posts a nifty animation showing the doorzone danger in many of your typical bike lanes.
The doorzone is the area near a car where a cyclist can get whacked if a cyclist rides too near a parallel parked car and somebody in the car opens the door. Opening a door on the traffic side without checking for traffic is illegal in all 50 states (and opening a door on the passenger side in front of a filtering cyclist is illegal in California), but getting “doored” is still fairly common, and in several cases dooring is lethal to the cyclist. Often, the cyclist is hit by a door and knocked directly into adjacent traffic.
This animated GIF from Streetsblog SF shows the bike lane doorzone.
And, and there’s a story to go along with this graphic as well: The SF Municipal Transportation Agency is piloting some paint in the bike lanes to show cyclists where the doorzone lies.
