Can I Sue If a Car Door Opens and Hits Me While Riding My Bike?

Short answer: yes.

Longer answer: California law is specifically written to protect you in this situation. The person who flung that door open without looking broke the law. Full stop.

Let’s talk about what happened, what the law says, and how to make sure you don’t eat the cost of someone else’s carelessness.

“Dooring” Is Illegal in California — and It Happens All the Time

Getting “doored” means someone inside a parked car opens their door right into your path while you’re riding your bike. You either slam into the door, go flying over it, or swerve into traffic trying to avoid it. None of those outcomes are good.

California Vehicle Code 22517 couldn’t be clearer:

“No person shall open the door of a vehicle on the side available to moving traffic unless it is reasonably safe to do so and can be done without interfering with the movement of such traffic.”

That applies to drivers and passengers. Both of them. Before they open the door, they’re supposed to look. If they don’t look and you get hurt, they violated the law.

This isn’t some gray area. It’s black and white. And a violation of CVC 22517 can serve as evidence of negligence all by itself — a legal concept called “negligence per se.” You don’t need to prove they were careless. The law already says they were.

Dooring Injuries Are No Joke

People who have never been doored tend to downplay it. “It’s just a door.” It’s not just a door. It’s a fixed, heavy metal object that stops you dead while you’re moving at 15-20 mph on zero protection.

Cyclists who get doored can end up with:

• Broken collarbones, wrists, and arms — The most common injuries from the initial impact
• Concussions and traumatic brain injuries — Even with a helmet
• Spinal injuries — From the impact or hitting the pavement
• Road rash and deep lacerations — Bare skin on asphalt at speed
• Facial and dental injuries — From hitting the door or the ground face-first
• Internal injuries — Blunt force trauma to the chest and abdomen

The real danger? When you swerve to dodge the door and get hit by a moving car. That secondary collision is often fatal. San Diego has seen cyclists killed from exactly this kind of accident.

Uber and Lyft Made This Problem Worse

Before rideshare, you could at least spot taxis by their markings and give them extra room. Uber and Lyft cars look like every other parked vehicle. Passengers hop out wherever the app tells the driver to stop — bike lane, no bike lane, it doesn’t matter. They open the door without a second thought.

The increase in dooring accidents in urban areas tracks directly with the rise of rideshare services. In a dooring case involving a rideshare vehicle, liability might fall on:

• The passenger who opened the door
• The Uber or Lyft driver who stopped in a dangerous location
• The driver’s or company’s insurance policy

An experienced attorney sorts out who owes what. The insurance picture in rideshare dooring cases can be messy — but the liability picture usually isn’t.

“But Were You Riding Too Close to the Cars?”

You already know this argument is coming. The person who doored you — or more likely, their insurance company — will say you were too close to the parked cars. That you were going too fast. That you should’ve been more careful.

Here’s the thing: CVC 21208 requires cyclists to use the bike lane when one is available. And guess where bike lanes run? Right next to parked cars. Right in the “door zone.”

California law literally puts you in the line of fire and then makes the person opening the door responsible for checking. The law is designed this way on purpose.

That said, California’s pure comparative negligence rules mean the other side might succeed in assigning you some percentage of fault. If they pin 10% on you and your case is worth $150,000, you’d recover $135,000. Your attorney’s job is to keep that percentage as low as possible — and the evidence from the scene is what makes that happen.

What to Do If You’ve Been Doored

The minutes after a dooring accident are chaos. You’re hurt, you’re angry, your bike might be totaled. But what you do next matters more than you think.

1. Don’t let the person leave. Get their name, phone number, driver’s license, and insurance info. If they’re a passenger, get the driver’s info too. If they won’t cooperate, grab the license plate.
2. Call 911. You want a police report, and you want it to say you were doored — which is a violation of CVC 22517. Make sure the officer documents it that way.
3. Get witnesses. Anyone who saw it happen — pedestrians, other cyclists, people at nearby businesses.
4. Photograph everything. The open door, the distance from the curb, the bike lane markings, your bike, your injuries, and the location of any rideshare stickers on the vehicle.
5. Go to the doctor. Even if it feels like you just got banged up. Concussions, hairline fractures, and internal bleeding don’t always announce themselves right away.
6. Don’t accept a quick settlement. The at-fault party’s insurance will lowball you before you even know how bad your injuries are.
7. Call a personal injury attorney. We deal with insurance companies so you don’t have to.

What’s Your Case Worth?

It depends on your injuries. But dooring cases can involve significant compensation because cycling injuries tend to be severe. You may be able to recover:

• All medical bills — ER, surgery, rehab, future treatment
• Lost income and reduced earning capacity
• Pain and suffering
• Bike and equipment replacement
• Emotional distress — including fear of riding again
