Dooring and right-hook collisions are among the most dangerous urban bicycle crashes. They can happen at relatively low vehicle speeds but still throw a rider into traffic, pavement, a curb, or another vehicle. Liability often depends on seconds of movement, visibility, lane position, and evidence that disappears quickly.
What Is a Dooring Collision?
A dooring collision occurs when a driver or passenger opens a vehicle door into the path of a bicyclist. The cyclist may strike the door directly or swerve into traffic to avoid it. The investigation should address where the vehicle was parked or stopped, how long it had been there, whether mirrors were checked, lighting, bicycle-lane design, and whether nearby video captured the event.
What Is a Right-Hook Collision?
A right hook occurs when a motorist turns right across the path of a bicyclist traveling in the same direction. The driver may pass and turn too soon, fail to check mirrors and blind spots, or misjudge the cyclist’s speed. Similar conflicts occur at driveways, parking-lot entrances, loading zones, and rideshare pickup areas.
Evidence That Can Prove Fault
- Damage to the bicycle, door, mirror, or turning vehicle
- Helmet, clothing, and personal-item damage
- Action-camera, dash-camera, or surveillance footage
- Witness statements and contemporaneous 911 calls
- Roadway, bicycle-lane, sightline, and parking photographs
- Vehicle position, debris, scrape marks, and impact measurements
- Traffic signal timing and public roadway records
Police citations can be useful, but they do not control the civil claim. Physical evidence, video, witnesses, and California traffic rules may support liability even when no citation was issued.
Comparative Fault Arguments
Insurers may argue that the cyclist was riding too fast, outside a bicycle lane, against traffic, without lights, or too close to parked cars. California follows pure comparative negligence, so partial fault does not automatically eliminate recovery. Each allegation should be compared with the actual roadway, time, lighting, traffic, and collision mechanics.
Roadway and Public Entity Claims
Some crashes involve blocked bicycle lanes, dangerous lane transitions, poor sightlines, defective signals, unsafe construction, or recurring parking conflicts. If a city, county, transit agency, or other public entity may share responsibility, a government claim commonly must be presented within six months. The roadway should be documented before it changes.
Common Bicycle-Collision Injuries
Dooring and right-hook crashes can cause wrist and shoulder fractures, clavicle injuries, knee trauma, facial injuries, dental damage, concussions, traumatic brain injuries, spinal injuries, road rash, scarring, and psychological trauma. Damaged helmets, torn clothing, and photographs help document impact severity beyond the vehicle’s exterior damage.
Insurance Sources
Coverage may come from the driver’s policy, the vehicle owner’s policy, an employer or commercial policy, a rideshare policy, or uninsured or underinsured motorist coverage. Household auto policies should also be reviewed because some may provide benefits even though the injured person was riding a bicycle.
