“The Danger Zone! Parked cars hide not only entering vehicles, but also people who walk out to get to the driver’s side. And the door of a parked vehicle can open up to 4 feet into the lane. If you ride just beyond the reach of the door, you are still at risk of being startled and swerving if it opens suddenly.
The Danger Zone: 1) Strike zone. 2) Startle zone. 3) Unusable road width. Sure, many people—even some bicycling “experts”—will tell you, “Always keep as far to the right as possible,” and, “Look out for opening car doors.” But at speeds above walking, you can’t react in time to avoid a car door. And you can’t see inside many cars to know whether a person is inside. If a door opens in front of you, you will hit the door unless you swerve out into the street—maybe into the path of a passing car. So to avoid being struck or startled, the end of your handlebar should be 5 feet or more from parked cars. Hold your line. Don’t weave in and out between parked cars. Don’t weave in and out between parked cars. If you weave into the parking lane, a parked car will hide you from drivers approaching from behind. Then you have to pop back into the path of overtaking traffic when you reach the next parked car. Put yourself in the place of a driver a couple of hundred feet behind you. Are you constantly visible and predictable? Motorists don’t mind slowing down for a predictable, visible bicyclist nearly as much as they mind a bicyclist who swerves out in front of them.”
