California has more registered cyclists, more bicycle commuters, and more bicycle infrastructure investment than any other state — and more bicycle fatalities than any state except Florida. Understanding the data behind California’s bicycle safety crisis is the first step toward changing it, and toward understanding your legal rights if you or a family member has been injured while riding.
This guide compiles the most current verified California bicycle accident statistics from primary government sources — UC Berkeley SafeTREC, the California Office of Traffic Safety, NHTSA, and CHP/SWITRS — and explains what the numbers mean for cyclists and their families. It is updated annually as new data becomes available.
1. California Bicycle Fatalities: Current Data and Trends
Statewide Fatality Trend (2014–2024)
| Year | CA Bicyclist Fatalities | Change Year-over-Year | Source |
| 2014 | ~93 | — | Baseline (FARS) |
| 2017 | ~130 | +40% from 2014 baseline | FARS/OTS |
| 2019 | ~125 | Pre-pandemic | FARS/OTS |
| 2020 | ~129 | +3.2% | FARS/OTS |
| 2021 | ~160 | +24% (pandemic surge) | FARS/OTS |
| 2022 | 183 | +14% (decade high) | OTS Quick Stats / SafeTREC |
| 2023 | 145 | −20.8% (largest single-year improvement) | OTS Quick Stats 2025 / SafeTREC 2025 |
| 2024 (provisional) | ~148 | Est. +2% from 2023 (SWITRS provisional) | CHP/SWITRS provisional; NHTSA early estimate |
Sources: California Office of Traffic Safety Quick Stats (July 2025); UC Berkeley SafeTREC 2025 Bicycle Safety Fact Sheet (FARS ARF 2023 / Provisional SWITRS 2023); CHP/SWITRS provisional 2024 data (updated December 2025); NHTSA FARS.
| TREND NOTE: The 2023 decline of 20.8% was the most significant single-year improvement in California bicycle safety in over a decade, and one of the best among high-volume states nationally. However, that improvement followed 2022’s decade high of 183 deaths — itself a 56% increase from 2014 baseline levels. California’s bicycle fatality count in 2023 remains roughly 56% above where it stood ten years earlier, a long-term deterioration that the 2023 improvement has not yet reversed. |
California vs. the Nation
| Metric | California (2023) | National (2023) | CA Share |
| Bicyclist fatalities | 145 | 1,377 (NSC) | ~10.5% of national total |
| Share of all traffic deaths | ~3.8% | ~2.8% | CA above national avg |
| Population share | ~11.6% | 100% | Disproportionate fatality share |
| Urban road fatality share | 88% | ~78% | CA more concentrated in cities |
| Fatal crashes — top 3 states (2022) | CA: 177-183; FL: ~215; TX: ~130 | — | CA consistently 2nd nationally |

2. California Bicycle Fatalities by County
California bicycle crash data is concentrated in the state’s most populous counties — Los Angeles, San Diego, Riverside, Orange, and San Bernardino — which consistently account for the majority of both crash volume and fatalities. The data below reflects the most recently available county-level breakdown from SWITRS and SafeTREC.
Top California Counties by Bicycle Fatality Count
| County | Fatalities (2021 — most recent detailed breakdown) | Serious Injuries (2022) | Notes |
| Los Angeles | 27 (highest in state) | 240+ | Consistently #1 by raw count; 2,072 total cyclists injured/killed in 2022 |
| San Diego | 16 | 180+ | Consistently top 3; 35–50 annual deaths historically |
| Riverside | 10 | 120+ | Inland Empire growth and high-speed arterials drive crash volume |
| Orange | 9 | 110+ | Dense cycling population; suburban arterial risk |
| Santa Clara | 9 | 100+ | Silicon Valley cycling commuter population |
| Sacramento | ~8 | 90+ | Growing cycling city; city ranks 4th for serious crash volume |
| San Bernardino | ~7 | 85+ | Similar risk profile to Riverside |
Sources: UC Berkeley SafeTREC 2024 Bicycle Safety Fact Sheet (FARS 2022, SWITRS 2022); SafeTREC 2023 Bicycle Safety Fact Sheet (2021 county rankings); UC Berkeley CATSIP Pedestrian and Bicycle Crash Data by County (2020–2024, updated December 2025).
Los Angeles County’s dominance in the crash data reflects both its size and its infrastructure challenges — a dense cycling population navigating a road network built primarily for automobiles. In 2022 alone, LA County recorded 2,072 total cyclists either injured or killed, including 176 children under the age of 15.
California Cities by Serious Bicycle Crash Volume (2023)
| Rank | City | Serious Injury / Fatal Crashes (2023) | Notes |
| 1 | Los Angeles | Highest in state | 15 cyclist deaths through August 2024 per LAPD data |
| 2 | San Francisco | High volume | Dense urban cycling; improving infrastructure |
| 3 | Sacramento | Moderate-high | Growing cycling city |
| 4 | San Jose | Moderate-high | Large cycling commuter base |
| 5 | San Diego | 131 serious/fatal crashes | Per city data 2023 |
3. What Is Causing California Bicycle Crashes
UC Berkeley SafeTREC’s analysis of SWITRS crash factor data identifies consistent patterns across California bicycle fatalities and serious injuries. These are the leading primary crash factors reported in official records:
| Primary Crash Factor | % of Fatal & Serious Injury Crashes (2023) | Notes |
| Unsafe speed | 16.5% | Leading factor in fatal crashes — speeding drivers on arterials strike cyclists at deadly force |
| Automobile right-of-way violation | 16.3% | Driver fails to yield; most common in left-turn and intersection crashes |
| Improper turning | 15.0% | Right-hook and left-cross collisions — driver turns across cyclist’s path |
| Traffic signals and signs violation | ~13% | Running red lights; failure to stop at signs |
| Wrong side of road | ~11% | Driver or cyclist traveling against traffic flow |
| DUI — alcohol/drugs | ~10% | Impaired drivers; disproportionate share of nighttime fatalities |
| Distracted driving | ~8% (underreported) | Phone use and inattention; official data undercounts |
Source: UC Berkeley SafeTREC 2025 Traffic Safety Facts — Bicycle Safety (FARS ARF 2023 / Provisional SWITRS 2023).
Crash Type Breakdown
| Crash Type | % of Fatal & Serious Injury Crashes (2023) | Legal Significance |
| Broadside (T-bone) | 34.9% | Most common type; typically involves driver failing to yield at intersection — strong driver liability |
| Other / complex | 22.6% | Includes dooring, road defect, multi-vehicle scenarios |
| Rear-end | 10.3% | Driver strikes cyclist from behind — very strong driver liability in California |
| Head-on | ~7% | Often involves wrong-way driver or cyclist — high fatality severity |
| Sideswipe | ~6% | Driver fails to maintain lane — three-foot passing law applies (CVC §21760) |
Source: UC Berkeley SafeTREC 2025 Traffic Safety Facts — Bicycle Safety (Provisional SWITRS 2023).
When Crashes Happen: Time and Day Patterns
- Fatal bicycle crashes peak on Saturday nights between 6 PM and 9 PM.
- 39.9% of all fatal bicycle crashes in California occur between 6 PM and midnight.
- Thursday and Saturday account for 44.3% of fatal bicycle crashes combined.
- Serious injury crashes (non-fatal) peak on Tuesday and Friday afternoons between 3 PM and 6 PM — reflecting commuter traffic patterns.
- 46% of all serious injury bicycle crashes occur between noon and 6 PM.

4. Who Is Most at Risk: Demographics
| Demographic Factor | Data (2022–2023) | Source |
| Male cyclists — share of fatalities | 74% of fatalities; 79% of serious injuries | SafeTREC 2025 (FARS 2023) |
| Age group most represented in fatalities | Ages 55–64 (20.6% of fatalities in 2022) | SafeTREC 2024 (FARS 2022) |
| Age group most represented in serious injuries | Ages 25–34 | SafeTREC |
| Children involved (LA County, 2022) | 176 children under 15 injured or killed | SafeTREC / OTS |
| Urban vs. rural fatalities | 88% urban road fatalities | FARS 2023 |
| Race/ethnicity reporting | Only 23.4% of 2023 fatalities had race recorded | SWITRS 2023 — data gap |
| THE AGE SHIFT: A notable trend in California bicycle fatality data is the increasing age of victims. Cyclists aged 55–64 now represent the single largest age group in fatalities — a demographic shift that reflects both the aging of California’s cycling population and the growth of recreational cycling (as opposed to commuter cycling) among older adults. This group is particularly vulnerable because older cyclists are more likely to suffer fatal injuries from crashes that younger riders might survive. |
5. The E-Bike Problem: A Rapidly Growing Risk Category
One of the most significant emerging trends in California bicycle safety data is the disproportionate injury rate associated with electric bicycles. E-bikes are heavier than traditional bicycles, capable of higher speeds (up to 28 mph for Class 3 e-bikes), and increasingly ridden by children and inexperienced cyclists. The injury data reflects these characteristics:
- Pediatric e-bike injuries — 1,600% increase. Children’s Hospital of Orange County (CHOC) recorded 7 pediatric e-bike injury cases in 2019 and 116 in 2024 — a 1,557% increase in five years. The injuries were more severe on average than traditional bicycle injuries.
- E-bike injuries more severe than traditional bicycle injuries. UC San Diego researchers found e-bike-related emergency room visits increased by over 70% in recent years. E-bike crash injuries trend toward head trauma and torso injuries rather than the extremity injuries more common in slower-speed traditional bicycle crashes.
- Speed is the key risk factor. E-bikes allow riders to travel at speeds that significantly increase injury severity in crashes, particularly for riders without prior cycling experience. Class 3 e-bikes (up to 28 mph) pose the greatest risk.
- Helmet law gap. California requires helmets for Class 3 e-bike riders under 18, and for all riders on Class 1 and 2 e-bikes under 18. Adults riding Class 1 or 2 e-bikes are not required to wear helmets — a significant gap given the higher crash severity data.
- Insurance coverage ambiguity. E-bikes occupy a gray zone between bicycles and motor vehicles for insurance purposes. Many homeowner and renter insurance policies cover traditional bicycle theft and liability but do not extend to e-bikes. Dedicated e-bike insurance is available but not widely purchased.
6. Road Type and Infrastructure: Where Fatal Crashes Concentrate
| Road Type / Infrastructure Factor | Share of Fatal Crashes | Notes |
| Urban roads (total) | 88% | The overwhelming majority of CA bicycle deaths occur on city streets, not rural roads |
| Minor arterials | ~37% | High-speed multi-lane streets through residential areas — the most dangerous road type per cyclist exposure |
| Principal arterials | ~34% | Together with minor arterials, account for ~71% of all fatal crashes |
| Local / residential streets | ~17% | Lower speed — lower fatality severity |
| State highways / freeways | ~12% | Prohibited for most cyclists but crashes occur at access points |
| Intersections vs. mid-block | Intersections: ~45%; Mid-block: ~55% | Mid-block crashes often involve higher vehicle speeds; intersection crashes involve right-of-way violations |
Sources: SafeTREC 2025 Bicycle Safety Fact Sheet; FARS ARF 2023; SWITRS 2023.
The concentration of fatal crashes on minor and principal arterials reflects what traffic engineers have documented consistently: the road types most used by cycling commuters are the same road types designed for high-speed through vehicle traffic. Until infrastructure investment separates cyclists from high-speed vehicles on these corridors, the fatality pattern will persist.

7. Your Legal Rights After a Bicycle Accident in California
If you or a family member has been struck by a vehicle while riding a bicycle in California, you have legal rights that extend well beyond filing an insurance claim. Our Los Angeles Bicycle Accident Lawyers practice page covers the full scope of those rights, but the key principles are summarized here.
Driver Liability
Under California Vehicle Code §21760, drivers must provide at least three feet of clearance when passing a cyclist. CVC §21950 requires drivers to yield to cyclists in crosswalks. CVC §22350 requires drivers to travel at a safe speed for conditions regardless of the posted limit. Violations of these provisions — combined with standard negligence principles — establish driver liability in the vast majority of bicycle injury cases.
Government Entity Liability
Defective road conditions — potholes, dangerous pavement edges, missing or inadequate bike lane markings, broken storm grates — that cause bicycle accidents may create liability for the City of Los Angeles, Caltrans, LA County, or other government agencies. However, claims against government entities require filing a government tort claim within six months of the accident date under Government Code §911.2. Missing this deadline permanently eliminates your right to sue.
Comparative Fault in Bicycle Cases
Insurance companies routinely argue that cyclists contributed to their own accidents — running a stop sign, riding without lights at night, failing to signal. Under California’s pure comparative negligence rule, even a cyclist who was partially at fault can still recover compensation, with damages reduced by their fault percentage. See our California Comparative Fault Law: Pure Comparative Negligence Explained for a detailed explanation of how this works in practice.
Hit-and-Run Bicycle Accidents
Hit-and-run bicycle accidents are disturbingly common in Los Angeles and Southern California — a reflection of the broader hit-and-run epidemic documented in our city and state data. If the driver who struck you fled the scene, your own uninsured motorist coverage typically applies, and other recovery options may exist. See our dedicated page on Bicycle Hit and Run Claims in Los Angeles for the full process.
Common Bicycle Accident Injuries and Their Legal Significance
The injuries sustained in bicycle accidents range from road rash and fractures to traumatic brain injury and spinal cord damage — the same injuries that produce the highest-value personal injury claims. For a detailed analysis of injury types, medical treatment timelines, and how injuries affect case value, see our Bicycle Accident Injuries in Los Angeles guide.

8. Frequently Asked Questions
How many bicyclists are killed in California each year?
145 bicyclists were killed in California in 2023, according to the California Office of Traffic Safety Quick Stats (July 2025) and UC Berkeley SafeTREC’s 2025 Bicycle Safety Fact Sheet. This was a 20.8% decrease from 183 deaths in 2022, which was a decade high. Provisional 2024 data from CHP/SWITRS suggests a slight increase to approximately 148 deaths. The 5-year average (2020–2024) is approximately 152 bicycle fatalities per year statewide.
What county in California has the most bicycle accidents?
Los Angeles County consistently records the highest bicycle crash volume in California by a significant margin. In 2021, LA County had 27 bicycle fatalities — the most of any county. In 2022, the county recorded 2,072 total cyclists either injured or killed, including 176 children under 15. San Diego, Riverside, Orange, and Santa Clara counties consistently rank 2nd through 5th.
What is the most dangerous time to ride a bicycle in California?
Saturday nights between 6 PM and 9 PM represent the peak period for fatal bicycle crashes in California. Nearly 40% of all fatal bicycle crashes occur between 6 PM and midnight. For serious (non-fatal) injury crashes, Friday afternoons between 3 PM and 6 PM are the most dangerous period, driven by commuter traffic volume and end-of-week driver fatigue.
Are e-bikes more dangerous than regular bicycles?
The data suggests e-bikes produce more severe injuries per crash than traditional bicycles, particularly for children and inexperienced riders. E-bikes are heavier and capable of higher speeds than traditional bicycles. Children’s Hospital of Orange County recorded a 1,557% increase in pediatric e-bike injuries between 2019 and 2024 (from 7 to 116 cases). E-bike crash injuries trend toward head trauma and torso injuries — more severe than the extremity injuries typical of slower-speed traditional bicycle crashes.
What are the most common causes of bicycle accidents in California?
According to UC Berkeley SafeTREC’s 2025 analysis of SWITRS crash data, the leading causes of fatal and serious injury bicycle crashes in California are: unsafe speed (16.5%), automobile right-of-way violations (16.3%), improper turning — particularly right-hook crashes (15.0%), traffic signal and sign violations (~13%), and wrong-side-of-road driving (~11%). Broadside collisions — a driver striking a cyclist from the side — are the most common crash type at 34.9% of all fatal and serious injury crashes.
Can I sue if I was hit by a car while riding my bike in California?
Yes. If a driver’s negligence caused your bicycle accident, you have the right to file a personal injury claim against the driver and their insurer. California law also allows cyclists to sue government entities for dangerous road conditions (defective pavement, missing infrastructure) if a government tort claim is filed within six months of the accident. Even if you were partially at fault — not wearing a helmet, running a stop sign — California’s pure comparative negligence rule allows you to recover compensation with your damages reduced proportionally to your fault percentage.
What is the three-foot rule for cyclists in California?
California Vehicle Code §21760 requires drivers to provide at least three feet of clearance between their vehicle and a cyclist when passing. If a driver cannot safely pass with three feet of clearance, they must slow down and wait until it is safe to pass with the required space. Violation of this rule is both a traffic infraction and strong evidence of negligence in a bicycle accident personal injury case.
Does helmet use affect my legal claim after a bicycle accident in California?
California law requires cyclists under 18 to wear helmets (Vehicle Code §21212). Adults are not required to wear helmets on public roads. In a personal injury case, a defendant may argue that your failure to wear a helmet contributed to your head injuries — a comparative fault argument. However, helmet non-use cannot bar your recovery under California’s pure comparative negligence rule; it can only reduce your damages attributable to head injuries that a helmet might have mitigated. It cannot be used to reduce recovery for injuries unrelated to head protection.
