🚲 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

Total damages determined $100,000
Cyclist found 20% at fault (outside bike lane) -$20,000
Driver found 80% at fault (failure to yield)
CYCLIST'S RECOVERY $80,000

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).

📝 Sample Demand Letter Language

Copy and customize these paragraphs for your bicycle accident demand letter.

Opening Paragraph
I am writing to demand compensation for injuries and damages I sustained when your insured, [DRIVER NAME], negligently struck me while I was lawfully operating my bicycle on [DATE] at approximately [TIME] on [LOCATION/STREET] in [CITY], California. Your insured violated California Vehicle Code Section 21760 (the Three Feet for Safety Act) and other traffic laws, causing me to suffer serious injuries requiring medical treatment.
3-Foot Law Violation
Your insured violated California Vehicle Code Section 21760, which requires motorists to maintain a minimum distance of three feet when overtaking and passing a bicyclist. Rather than providing the legally required clearance, your insured passed within [ESTIMATED DISTANCE] of my bicycle, [striking me / forcing me to take evasive action that caused me to crash]. This violation constitutes negligence per se under California Evidence Code Section 669, establishing your insured's liability as a matter of law.
Right Hook Collision
Your insured violated California Vehicle Code Sections 21717 and 22107 by executing a right turn directly across my path of travel without first ascertaining that the movement could be made safely. I was proceeding lawfully in the [bike lane / right lane] when your insured turned right in front of me, cutting off my lane of travel and striking me. Under VC 21200, I had the same right to the roadway as any motor vehicle, and your insured was required to yield to my right-of-way before turning.
Dooring Incident
Your insured violated California Vehicle Code Section 22517, which prohibits opening a vehicle door on the side available to moving traffic unless it can be done safely without interfering with traffic. Your insured opened their [driver's side / passenger side] door directly into my path of travel as I was lawfully proceeding in the [bike lane / traffic lane]. I had no opportunity to avoid the suddenly opened door and was thrown from my bicycle, sustaining serious injuries.
Cyclist Rights Emphasis
Under California Vehicle Code Section 21200, bicyclists have all the rights applicable to the driver of a vehicle. I was lawfully operating my bicycle [in the bike lane / taking the full lane as permitted by VC 21202 because the lane was too narrow to share safely]. Your insured had a duty to watch for bicyclists, maintain a safe distance, and yield the right-of-way as required by law. Your insured breached these duties, directly and proximately causing my injuries.
Injuries Description
As a direct result of this collision, I sustained the following injuries: [LIST INJURIES - e.g., fractured clavicle, road rash on left arm and leg, concussion, torn rotator cuff]. I was transported by ambulance to [HOSPITAL NAME] where I received emergency treatment including [TREATMENT DETAILS]. I have since undergone [NUMBER] follow-up appointments, [NUMBER] physical therapy sessions, and continue to experience [ONGOING SYMPTOMS]. Medical records documenting these injuries are enclosed.
Property Damage - Bicycle
The collision destroyed my [YEAR/MAKE/MODEL] bicycle, valued at $[VALUE]. The frame was [cracked/bent/totaled], and components including the [LIST DAMAGED PARTS] were destroyed. An assessment from [BIKE SHOP NAME] confirms the bicycle cannot be safely repaired and must be replaced. Additionally, my cycling equipment including [helmet, shoes, clothing, accessories] was destroyed, with a combined replacement value of $[AMOUNT]. Receipts and the bike shop assessment are enclosed.
Damages Demand
Based on the foregoing, I hereby demand the sum of $[TOTAL AMOUNT] to fully compensate me for my injuries and damages. This amount includes: medical expenses of $[AMOUNT]; future medical expenses estimated at $[AMOUNT]; lost wages of $[AMOUNT]; property damage of $[AMOUNT]; and pain, suffering, and loss of enjoyment of life of $[AMOUNT]. I require a response to this demand within [30] days. If I do not receive an acceptable settlement offer by [DEADLINE DATE], I will have no choice but to pursue all available legal remedies, including filing a civil lawsuit.
E-Bike Specific Language
At the time of the collision, I was operating a Class [1/2/3] electric bicycle as defined by California Vehicle Code Section 312.5. Under California law, electric bicycles have all the same rights as traditional bicycles, and I was lawfully operating in the [bike lane / roadway]. My e-bike, a [MAKE/MODEL] with a value of $[VALUE], was destroyed in the collision. The motor, battery, and frame all sustained damage beyond repair, as documented in the enclosed assessment.

🚀 Next Steps

What to do after sending your bicycle accident demand letter.

Expected Timeline

Days 1-14

Insurance company receives and assigns an adjuster to review your demand

Days 14-30

Adjuster reviews medical records, police report, and evaluates liability

Days 30-45

Initial response with counteroffer, request for more information, or denial

If the Insurance Company Lowballs or Denies

  1. Don't Accept the First Offer

    Initial offers are typically 25-50% of claim value. This is a starting point for negotiation, not a final offer. Respond with a counteroffer supported by your evidence.

  2. Consult a Bicycle Accident Attorney

    Personal injury attorneys who handle bicycle cases understand the unique issues. Many work on contingency (no fee unless you win). Free consultations are standard.

  3. Consider Filing Suit

    Filing a lawsuit often prompts more serious settlement negotiations. California Superior Court handles claims over $10,000. Small claims court handles up to $10,000.

  4. Explore Uninsured/Underinsured Motorist Coverage

    If the driver has insufficient insurance, your own auto policy's UM/UIM coverage may apply to bicycle accidents. Check your policy or consult an attorney.

🚨 Watch These Deadlines

  • Personal injury claims: 2 years from accident date (CCP 335.1)
  • Claims against government: 6 months to file tort claim (GC 911.2)
  • Property damage: 3 years from accident date (CCP 338)
  • Hit and run: Report immediately; may affect UM coverage

A demand letter does NOT stop the statute of limitations clock. If your deadline is approaching, consult an attorney immediately.
