Dooring Accident Claims: When a Car Door Hits a Phoenix Cyclist

A dooring accident cyclist Phoenix riders describe usually happens in under a second. A parked car’s door swings open directly into a bike lane or the path a cyclist is riding. There’s no time to brake or swerve. Arizona has a specific statute for exactly this scenario. It sits apart from the general right-of-way rules that govern most other bike-versus-car claims. It places the legal burden squarely on the person who opened the door, not the cyclist who hit it.

Dooring accident cyclist Phoenix claims run on A.R.S. § 28-905

A.R.S. § 28-905 covers this exactly. A person may not open a car door unless it’s reasonably safe to do so. The opening also can’t interfere with moving traffic. The statute also bars leaving a door open on the traffic side of a car longer than necessary to load or unload. It applies to a parked car’s driver or any passenger. A violation counts as evidence of negligence in a resulting injury claim. Most Arizona bicycle law borrows from the general rules of the road under A.R.S. § 28-812. This statute exists specifically because of how often car doors and cyclists collide.

Why fault usually lands on the door-opener

The “door zone” is the roughly five-foot strip beside parked cars where a suddenly opened door can reach. It’s a known hazard, and this statute is built around it. A cyclist riding at a normal, lawful distance from parked cars who gets doored has a strong statutory case. The driver or passenger had the duty to check before opening, not the cyclist to anticipate an unpredictable door swing. Arizona’s comparative fault rule still applies, though. A cyclist riding well inside the door zone, when a marked bike lane or safer path was available, can still see some fault land back on them, even with the statute on their side.

Who’s actually liable: driver, passenger, or rideshare

Liability follows whoever physically opened the door, not necessarily whoever was driving. A rideshare passenger exiting a Waymo, Uber, or Lyft into a bike lane creates the same statutory violation as any other doored car. The passenger, not the driver or the rideshare company, typically bears responsibility for that specific act. Valet and delivery drivers who repeatedly park and exit vehicles along commercial corridors are a recurring source of dooring claims. That’s simply a function of how often they’re getting in and out of a vehicle during a shift.

Building the claim quickly

Dooring injuries often look less dramatic than a direct bike-versus-car collision, since the impact speed is lower. The injuries from being thrown off a moving bike can still be serious. Wrist fractures, shoulder injuries, and head trauma without a helmet are all common. Witness accounts matter heavily here, since the incident happens fast. A driver’s own account often understates how quickly and widely the door opened. Photographing the parked car’s position against any bike lane markings helps show how much of the door zone the cyclist actually had to work with.

The bottom line

A dooring accident cyclist Phoenix riders bring isn’t a close call under Arizona law. The statute puts the duty on the person opening the door. Most of these claims turn less on who was at fault and more on documenting the injury and the door’s position quickly, before memories and marks on the pavement fade.
