🚲 California Bicycle Accident Overview
California is one of the most bike-friendly states in the nation, with comprehensive laws protecting cyclists. When a driver's negligence causes a bicycle accident, injured cyclists have strong legal remedies under California Vehicle Code and common law negligence principles.
Common Causes of Bicycle Accidents
🚗 Passing Too Close
Drivers violating the 3-foot passing law (VC 21760) by passing bicyclists with insufficient clearance
🚫 Right Hook Collisions
Drivers turning right across a cyclist's path, cutting off bike lanes at intersections
🚪 Left Cross Accidents
Drivers turning left in front of oncoming cyclists, failing to yield right-of-way
🚧 Dooring Incidents
Drivers or passengers opening car doors into the path of cyclists (VC 22517)
Why Bicycle Accidents Are Unique
Bicycle accidents present distinct challenges compared to car-vs-car collisions:
- Severity of injuries - Cyclists lack the protective shell of a vehicle, leading to more serious injuries even at low speeds
- Bias against cyclists - Insurance adjusters often attempt to blame cyclists unfairly
- Unique damages - Bike damage, specialized gear replacement, and loss of cycling ability
- Road hazard factors - Potholes, debris, and road design issues may implicate government entities
- Witness credibility - Motorists may claim they "didn't see" the cyclist
👍 What You Can Recover
- Medical expenses - Emergency care, surgery, rehabilitation, future treatment
- Lost wages - Time missed from work and reduced earning capacity
- Pain and suffering - Physical pain, emotional distress, loss of enjoyment
- Property damage - Bicycle repair/replacement, gear, accessories
- Loss of consortium - Impact on family relationships
- Punitive damages - In cases of egregious conduct (DUI, road rage)
⚠ Statute of Limitations
California has strict time limits for filing bicycle accident claims:
- Personal injury: 2 years from the date of the accident (CCP 335.1)
- Property damage: 3 years from the date of the accident (CCP 338)
- Government entity: 6 months to file a government tort claim (GC 911.2)
Act quickly to preserve your rights and evidence.
⚖ California Cyclist Rights (VC 21200-21212)
California Vehicle Code establishes that bicyclists have the same rights and responsibilities as motor vehicle operators. Understanding these laws strengthens your demand letter.
Key Vehicle Code Provisions
Vehicle Code 21200 - Rights and Duties
A person riding a bicycle upon a highway has all the rights and is subject to all the provisions applicable to the driver of a vehicle. Cyclists are entitled to the same respect and consideration as motorists.
Vehicle Code 21202 - Lane Position
Cyclists riding slower than traffic shall ride as close to the right-hand curb as practicable, EXCEPT when: (1) passing, (2) preparing for a left turn, (3) avoiding hazards, (4) lane is too narrow to share, or (5) approaching a right turn. This gives cyclists discretion to "take the lane" when safety requires.
Vehicle Code 21208 - Bike Lane Use
When a bike lane has been established, cyclists shall ride within the bike lane except when: (1) passing, (2) preparing for a left turn, (3) leaving the roadway, or (4) avoiding hazards in the bike lane. Cyclists are NOT required to stay in dangerous bike lanes.
Vehicle Code 21209 - Motorist Prohibited in Bike Lane
No person shall drive a motor vehicle in a bicycle lane except when: making a turn, entering or leaving the roadway, or when required to cross the lane to park. Motorists who drive in bike lanes and strike cyclists violate this code section.
Vehicle Code 22517 - Opening Vehicle Doors
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 traffic. This is the "dooring" statute - violations are per se negligence.
Cyclist Right-of-Way Rules
🟢 At Intersections
Cyclists proceeding straight have right-of-way over turning vehicles (VC 21800-21804). Drivers must yield before turning.
🟢 In Crosswalks
Cyclists walking their bikes in crosswalks have pedestrian right-of-way (VC 21200). Drivers must stop for pedestrians.
🟢 Lane Changes
Drivers must ensure it is safe before changing lanes and may not cut off cyclists (VC 21658, 22107).
🟢 Taking the Lane
Cyclists may ride in the center of a lane when the lane is too narrow to share safely (VC 21202(a)(3)).
💡 "Per Se" Negligence
When a driver violates a Vehicle Code section designed to protect cyclists, this establishes "negligence per se" under Evidence Code 669. The violation itself proves the driver was negligent - you only need to prove causation and damages.
🚗 California's 3-Foot Passing Law (VC 21760)
California's Three Feet for Safety Act (Vehicle Code 21760) is one of the most important laws protecting cyclists. Violations of this law create strong liability for drivers.
Vehicle Code 21760 - Three Feet for Safety
(a) The driver of a motor vehicle overtaking and passing a bicycle proceeding in the same direction on a highway shall do so at a safe distance that does not interfere with the safe operation of the overtaken bicycle, having due regard for the size and speed of the motor vehicle and the bicycle, traffic conditions, weather, visibility, and the surface and width of the highway.
(b) A driver of a motor vehicle shall not overtake or pass a bicycle proceeding in the same direction on a highway at a distance of less than three feet between any part of the motor vehicle and any part of the bicycle or its operator.
(c) If the driver cannot give three feet of clearance due to traffic or roadway conditions, the driver shall slow to a speed that is reasonable and prudent, and may pass only when doing so would not endanger the safety of the operator of the bicycle, taking into account the size and speed of the motor vehicle and bicycle, traffic conditions, weather, visibility, and surface and width of the highway.
How the 3-Foot Law Supports Your Claim
⚖ Establishes Clear Standard
Three feet is an objective, measurable standard. Any contact or near-contact while passing likely violates this law.
💰 Creates Liability
A violation is an infraction (fine $35-$220 without injury). If the violation causes bodily injury, it's a $220 fine plus points on license.
📝 Per Se Negligence
Violation of VC 21760 establishes negligence per se - the driver was automatically negligent as a matter of law.
🔍 Applies Even Without Contact
If a driver's close pass causes you to swerve and crash, the violation applies even without direct contact.
Proving a 3-Foot Violation
Evidence that helps establish a passing distance violation:
- Witness statements - Other motorists, pedestrians, or fellow cyclists who saw the pass
- Bicycle camera footage - Rear-facing cameras (increasingly common) capture passing distance
- Dashcam or traffic camera - May show the vehicle's position relative to cyclist
- Physical evidence - Contact marks, debris patterns, point of impact
- Expert reconstruction - Accident reconstructionist can calculate passing distance
- Driver admission - Statements like "I didn't see them" or "I thought I had room"
🚨 Common Driver Defenses - And How to Counter Them
- "The cyclist swerved into me" - Road conditions, debris, or the driver's close approach may have caused the swerve
- "There wasn't room to pass safely" - Then the driver was required to wait until there was room (VC 21760(c))
- "The cyclist was riding erratically" - Cyclists may need to avoid hazards; this doesn't excuse unsafe passing
- "I didn't see the cyclist" - Failure to see what should be seen is negligence, not a defense
⚡ E-Bike Classifications (AB 1096 / VC 312.5)
California's Assembly Bill 1096 (2015) created a three-tier classification system for electric bicycles under Vehicle Code 312.5. Understanding these classifications is essential for e-bike accident claims.
| Class | Motor Type | Max Speed | Where Allowed |
|---|---|---|---|
| Class 1 | Pedal-assist only (no throttle) | 20 mph max assist | Bike lanes, bike paths, multi-use trails (unless locally prohibited) |
| Class 2 | Throttle-assisted (motor can propel without pedaling) | 20 mph max motor speed | Bike lanes, bike paths (trails vary by jurisdiction) |
| Class 3 | Pedal-assist only (no throttle) | 28 mph max assist | Bike lanes on roads only; prohibited on most bike paths and trails |
Key E-Bike Legal Points
Vehicle Code 312.5 - E-Bike Definition
An electric bicycle is a bicycle equipped with fully operable pedals and an electric motor of less than 750 watts. E-bikes are NOT motor vehicles under California law and are subject to bicycle regulations, not motorcycle regulations.
Vehicle Code 21213 - Class 3 Requirements
Class 3 e-bike riders must be at least 16 years old and must wear a helmet. Class 3 e-bikes must have a speedometer. Passengers on Class 3 e-bikes must also be 16+ and wear helmets.
⚖ Same Rights as Bicycles
E-bike riders have the same rights as traditional cyclists under VC 21200. All protections including the 3-foot law apply equally.
💰 Same Insurance Recovery
E-bike riders can recover damages the same as traditional cyclists. Higher speeds may affect comparative fault analysis but don't bar recovery.
📝 Equipment Defects
E-bike accidents may involve product liability claims against manufacturers for battery fires, motor failures, or brake defects.
🚗 Speed Perception Issues
Drivers often underestimate e-bike speeds. A Class 3 e-bike at 28 mph approaches moped speeds - this affects driver duty of care.
⚠ Modified or Non-Compliant E-Bikes
E-bikes modified to exceed speed limits or with motors over 750 watts may be classified as motorized vehicles, which can affect:
- Where you can legally ride (may lose bike lane/path access)
- Insurance requirements (may need motor vehicle insurance)
- Comparative fault analysis (riding illegally may reduce recovery)
- Licensing requirements (may need M1/M2 license)
Always ensure your e-bike complies with California classification requirements.
⚖ Comparative Fault in Bicycle Accidents
California follows a "pure comparative negligence" system. This means you can recover damages even if you were partially at fault - your recovery is simply reduced by your percentage of fault.
California Civil Code 1714(a) - Pure Comparative Negligence
Everyone is responsible for their own negligence. In Li v. Yellow Cab Co. (1975) 13 Cal.3d 804, the California Supreme Court adopted pure comparative negligence. Each party pays only for their percentage of fault.
How Comparative Fault Works
📊 Comparative Fault Example
Cyclist hit while not using bike lane; driver failed to yield
Common Cyclist Fault Arguments (And Defenses)
🚫 "Cyclist wasn't wearing a helmet"
▼The Law: California only requires helmets for riders under 18 (VC 21212). Adult helmet use is not required by law.
Defense: Lack of helmet is NOT negligence per se for adults. However, in head injury cases, defense may argue it contributed to injury severity. Counter by noting: (1) no legal duty, (2) helmet may not have prevented the specific injury, (3) focus on driver's duty to avoid the collision entirely.
🚫 "Cyclist was riding outside the bike lane"
▼The Law: VC 21208 allows cyclists to leave bike lanes for safety, passing, turning, or to avoid hazards. VC 21202 allows taking the full lane when it's too narrow to share.
Defense: Cyclists are NOT required to ride in bike lanes at all times. Document why you were outside the lane (debris, parked cars, turning vehicle, narrow lane). The driver still had a duty to pass safely regardless of your lane position.
🚫 "Cyclist didn't have lights at night"
▼The Law: VC 21201 requires a white front light visible from 300 feet, a red rear reflector visible from 500 feet, and pedal/ankle reflectors or reflectorized shoes. This is a legitimate safety requirement.
Defense: If you had proper lights, emphasize this. If you didn't, note that: (1) driver still has duty to watch for all road users, (2) other visibility factors (streetlights, reflective clothing) may have made you visible, (3) the driver's headlights should have illuminated you regardless.
🚫 "Cyclist ran a stop sign/red light"
▼The Law: Unlike some states, California does NOT have an "Idaho Stop" law. Cyclists must obey all traffic signals (VC 21200).
Defense: If you obeyed traffic laws, emphasize this with witness testimony or camera footage. If you didn't, examine whether: (1) you had entered the intersection before the violation became relevant, (2) the driver's negligence was the superseding cause, (3) the driver was also violating traffic laws.
🚫 "Cyclist was wearing headphones"
▼The Law: VC 27400 prohibits wearing earplugs or headphones covering BOTH ears while cycling. One-ear devices are legal.
Defense: If using bone-conduction or single-ear devices, you were legal. If using both ears: (1) establish whether you could still hear traffic, (2) note that cyclists primarily rely on vision, not hearing, (3) driver's duty to pass safely exists regardless of cyclist's hearing ability.
💡 Key Takeaway: You Can Still Recover
Even if you were partially at fault, California's pure comparative negligence system allows you to recover damages. A cyclist found 40% at fault still recovers 60% of their damages. Insurance companies often overstate cyclist fault to reduce payouts - don't accept their assessment without pushback.
💰 Calculating Bicycle Accident Damages
Bicycle accidents often result in serious injuries due to the cyclist's vulnerability. California law allows full compensation for all damages caused by the at-fault driver's negligence.
Categories of Damages
| Damage Type | Description |
|---|---|
| Medical Expenses | Emergency room, hospitalization, surgery, physical therapy, medication, medical equipment, future treatment costs. Bicycle injuries often involve road rash, fractures, TBI, and spinal injuries. |
| Lost Wages | Time missed from work, reduced hours, inability to perform job duties. Include sick/vacation time used, self-employment losses, and bonuses/commissions lost. |
| Loss of Earning Capacity | If injuries prevent you from returning to your previous career or reduce your earning potential, you can recover the difference over your remaining work life. |
| Property Damage | Bicycle repair or replacement, helmet, cycling clothing, accessories (computer, lights, bags), cycling shoes, and any other damaged property. |
| Pain and Suffering | Physical pain, emotional distress, anxiety, depression, PTSD (common in cyclists after collisions), fear of cycling, loss of enjoyment of life. |
| Loss of Consortium | Impact on marital relationship, including loss of companionship, affection, and intimacy. Claimed by the injured person's spouse. |
Bicycle-Specific Damages
🚲 High-End Bicycle Value
Road bikes, mountain bikes, and e-bikes can cost $2,000-$15,000+. Full replacement value includes comparable frame, components, and accessories.
🥼 Cycling Gear Replacement
Helmets ($50-$300), cycling shoes ($100-$400), kit/clothing ($100-$500), sunglasses ($50-$250), GPS computers ($200-$600).
🚘 Loss of Cycling Ability
If you can no longer cycle for transportation, exercise, or recreation, this is a significant loss of enjoyment of life compensable as general damages.
🏋 Competitive Cyclist Losses
Amateur or professional racers may lose sponsorships, prize money, ranking points, and training investments. Document your competitive history.
