A Motorcyclist’s Nightmare: Who is at Fault in a California “Dooring” Accident?

What Happens When a Motorcyclist is Doored? Who’s at Fault?

It happens in a split second. You’re riding down a city street, and a car door is suddenly flung open directly in your path. With no time to react, you either slam into the door or swerve dangerously into the path of other traffic. It is one of a motorcyclist’s worst nightmares.

These “dooring” accidents are terrifying, and the injuries are often severe. In the chaotic aftermath, the person who opened the door may try to shift the blame. But you need to know the truth: the law is squarely on your side.

This guide will explain California’s dooring law, the common tactics insurance companies use to deny claims, and how to protect your rights after this uniquely dangerous type of motorcycle accident.

 

The Law is Clear: Dooring is Negligent in California

In the eyes of the law, a dooring collision is not an “accident”—it is an act of negligence. California Vehicle Code 22517 states:

“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…”

This law places a clear and direct duty on drivers and their passengers to check for traffic—including motorcyclists—before opening their door. When they fail to do so, they are breaching that duty and are legally liable for the harm they cause.

 

The “Lane Splitting” Defense: How Insurance Companies Fight Back

Even with a clear law, the at-fault party’s insurance company will still try to blame you, the rider. Their most common tactic is the “lane splitting” defense.

They will argue that because you were riding between lanes of cars (which is legal in California), you were partially at fault for the accident because you placed yourself in a dangerous position. They will use this argument to try and reduce the value of your claim under California’s comparative negligence rule.

An experienced motorcycle accident attorney knows how to counter this argument effectively. We argue that a driver’s duty to look before opening their door applies to all traffic, including a lawfully lane-splitting motorcyclist. The driver’s failure to check their mirror is the primary cause of the crash, not your position on the road.

A Record of Success in Dooring Cases: Our $150,000 Settlement

Expertise in this specific type of accident matters. We represented a motorcyclist who was seriously injured when a driver suddenly opened his car door in downtown Oakland. The impact threw our client from his bike, resulting in a fractured wrist that required surgery. The insurance company initially tried to blame our client. We fought back, demonstrating the driver’s clear violation of the law. We successfully secured a $150,000 settlement that covered our client’s surgery, lost income, and the long-term impact of his injuries.

Frequently Asked Questions about Dooring Accidents

 

1. Who is liable if a passenger doors a motorcyclist?
Both the passenger and the driver can be held liable. The passenger is negligent for failing to look, and the driver (often the vehicle's owner) is responsible for the unsafe actions of their passenger and for stopping in a location where it might be unsafe to open a door.
2. What are the most common injuries in a dooring accident?
Common injuries include broken clavicles (collarbones), fractured wrists and arms, severe road rash, and head, neck, or spinal cord injuries if the rider is thrown into traffic and struck by another vehicle.
3. What should I do immediately after being doored?
If you can, move to a safe location. Call 911 to report the accident and request medical help. Get the driver's and any passenger's information. Use your phone to take photos of the car, the open door, the position of your bike, and your injuries.
4. Can I still be blamed if I wasn't in a designated bike lane?
Yes, the insurance company will try. However, the law protects all "moving traffic," not just those in a bike lane. A motorcyclist lawfully using a lane of travel is protected by the dooring statute.
5. Is the city ever at fault for a dooring accident?
In rare cases, yes. If a city designs a bike lane that is dangerously close to a parking lane, creating a known "door zone" where accidents frequently happen, they may share some liability for creating a dangerous road condition.
