The Most Dangerous Places for Bicyclists in San Francisco: 2025 Update

San Francisco recorded its deadliest year on the roads in 2024, with 43 total traffic fatalities, including 3 cyclists killed after achieving a historic milestone of zero bicycle deaths in 2023. In 2026, the city confronts a mounting crisis: bicycle ridership continues to surge while infrastructure improvements lag dangerously behind.

For more than six decades, the bicycle accident attorneys at Walkup, Melodia, Kelly & Schoenberger have fought for safer streets and roads and justice for injured cyclists throughout the Bay Area. As proud sponsors of the San Francisco Bicycle Coalition and devoted cyclists ourselves, we understand that every injured rider represents a life forever changed by a preventable tragedy.

2024’s Devastating Safety Crisis

The Vision Zero Traffic Fatalities: 2024 End of Year Report, published by the San Francisco Department of Public Health in July 2025, documents a reversal in road safety:

  • 43 total traffic deaths in 2024 — a 65% increase from 2023 and the highest count since 2005
  • 3 bicycle fatalities — all victims were senior citizens aged 65 and older
  • 24 pedestrian deaths — a 33% increase from the previous year

These numbers mark a devastating end to the city’s decade-long Vision Zero initiative, which aimed to eliminate all traffic deaths by 2024.

A Reversal of a Safer 2023

The 2023 End of Year Report celebrated an unprecedented achievement: zero cyclists killed, the first year without a bicycle fatality since Vision Zero tracking began. That historic progress lasted just one year.

Current Bicycle Crash Statistics

The San Francisco Traffic Crashes Report 2023-2024, published by SFMTA in August 2025, reveals:

  • 469 bike-involved injury collisions in 2024
  • Approximately 500 total bike-related incidents concentrated on high-injury corridors
  • Over 70% of injury collisions at intersections
  • Five of the top six fatal crash violations were determined to be driver-at-fault

The five-year average (2020-2024) shows 416 serious bicycle accidents annually involving motor vehicles.

The Bicycle Boom Continues

Despite growing dangers, San Francisco’s cycling community continues to expand:

  • Over 100,000 estimated daily bike trips in 2024, a 22% increase over 10 years
  • 3.3 million Bay Wheels bike share rides in 2024, a 30% jump from 2023
  • Market Street experienced 25% more cyclists in 2024 when compared to 2023
  • 29% of San Francisco residents bike or roll weekly, according to SFMTA data

UC San Francisco researchers documented that e-bicycle injuries doubled annually from 2017 to 2022, while e-scooter injuries rose by 45% each year.

Most Dangerous Neighborhoods in 2025

According to the San Francisco Standard analysis of 2020-2024 data, these neighborhoods present the highest risk for cyclists:

Top 10 Most Hazardous Areas

  1. Mission District — Continues as the highest-risk area with persistent safety challenges
  2. South of Market (SoMa) — Heavy traffic and complex intersections create ongoing danger
  3. Civic Center — High pedestrian and vehicle traffic volumes put cyclists at risk
  4. Tenderloin — Dense urban environment with multiple conflict points
  5. Western Addition — Mixed residential and commercial traffic patterns cause confusion
  6. Financial District — Heavy commuter traffic during peak hours places cyclists in danger
  7. Downtown/Union Square — Tourist activity and delivery trucks increase risk
  8. Hayes Valley — Narrow streets and busy intersections make biking dangerous
  9. Golden Gate Park — Recreational cycling conflicts with vehicle traffic are present particularly on weekends
  10. Bayview — District 10 was the only area to see an increase in injury crashes compared to pre-pandemic averages, according to the SFMTA Traffic Crashes Report

Peak Danger Times

Afternoon rush hours (3 p.m. to 6 p.m.) remain the most hazardous for cyclists, with 101 bicycle crashes recorded during this period in data from California’s Transportation Injury Mapping System. Weekends also show elevated risk, with Saturdays recording the highest numbers of crashes.

Major Infrastructure Changes in 2025

Valencia Street Reconstruction

In November 2024, SFMTA voted to remove the controversial center-running bike lane on Valencia Street. Construction on the new side-running protected bike lane began on February 10, 2025.

The Biking and Rolling Plan

In March 2025, the SFMTA board unanimously approved the city’s first comprehensive bike network overhaul in 16 years:

  • 385 routes targeted for upgrades over the next 20 years (through 2045)
  • Goal: Every resident within a quarter mile of protected bike access
  • Priority neighborhoods: Tenderloin, SoMa, Fillmore, Excelsior, and Bayview-Hunter’s Point
  • 10% of city streets will be linked to a connected bike network

“The updated plan is designed for users historically left out of bicycle planning,” explained SFMTA senior transportation planner Christy Osorio, including “students, families, caregivers, and people with disabilities.”

Primary Causes of Bicycle Crashes

Hit-and-Run Epidemic

Hit-and-run crashes remain one of the most serious ongoing safety challenges for San Francisco cyclists, leaving victims without recourse when drivers flee.

Dooring Incidents

San Francisco Standard’s analysis of city logs found doorings were the second-most common cause of bicyclist-motor-vehicle injury in 2024:

  • 416 dooring incidents from 2014-2024
  • 10% of all 4,230+ bicyclist-motor-vehicle injury crashes are dooring related
  • 11% of injury collisions where the bicyclist was not at fault involved drivers opening doors into moving traffic (CVC 22517 violations), according to the SFMTA Traffic Crashes Report

Infrastructure Gaps

According to SFMTA data, the agency has added over 450 miles of bikeways in San Francisco over the last 10 years, yet the vast majority lack physical protection from vehicle traffic.

Driver-At-Fault Violations

The SFMTA Traffic Crashes Report documents the leading causes:

  • Unsafe lane changes (CVC 22107) jumped from 7% to 11% of crashes by 2024
  • Failure to yield when making left or U-turns (CVC 21801 A)
  • Opening a door into moving traffic (CVC 22517)
  • Speeding and driver negligence
  • Distracted driving (texting, phone use)
  • Driving under the influence
  • Roadway surface defects

Vision Zero: A Failed Decade

San Francisco adopted Vision Zero in 2014 with the goal of eliminating traffic deaths by 2024. After installing more than 13,000 traffic safety treatments, the goal has not been achieved.

The Enforcement Collapse

Mission Local’s analysis of the Civil Grand Jury report and CBS San Francisco coverage documented a catastrophic failure in traffic enforcement:

  • Citations dropped 95% from 2014 to 2022 (from over 120,000 to about 4,000)
  • 2024 citations: 15,550 — still 87% below 2014 levels
  • 2024 was the deadliest year since 2007

“Looking at the cold, raw data, it’s as if we haven’t done a thing. We have the same number of people dying every year since we started.” — SFMTA Board Member Steve Heminger

The High Injury Network

The 2024 End of Year Report confirms that 68% of severe and fatal traffic crashes occur on just 12% of streets:

  • 47% of all 2024 fatalities occurred on these 128 miles of streets
  • 44% of the High Injury Network is in Equity Priority Communities
  • SFMTA has completed Quick-Build safety improvements on 34 High Injury Network streets

Current Safety Initiatives

Speed Safety Cameras

California State Assembly Bill 645 authorized San Francisco as one of six cities to conduct a five-year study of Speed Safety Cameras. Vision Zero SF reports these cameras have shown almost 50% reductions in severe and fatal crashes in other cities.

2025 Traffic Fatality Data

According to SF.gov’s Traffic Fatalities database, traffic fatality data has a one-month reporting lag as SFDPH, SFPD, and SFMTA representatives meet monthly to reconcile deaths using Office of the Medical Examiner and SFPD data.

The Role of Legal Advocacy

While proper protective gear can help prevent severe injury, cyclists remain extremely vulnerable in any crash. Severe injuries are common, and survivors may require surgery, rehabilitation, lengthy hospitalization, and may sustain permanent disability.

Moving Forward

After achieving zero bicycle fatalities in 2023, San Francisco experienced its deadliest year overall since 2007 in 2024. The newly approved Biking and Rolling Plan offers hope, but implementation will take two decades.

As trial lawyers committed to fighting for safer streets, we continue to advocate for:

  • Accelerated implementation of protected bike infrastructure
  • Increased traffic enforcement to reverse the 87% decline in citations
  • Focused improvements on the High Injury Network, where 68% of crashes occur
  • Priority for Equity Priority Communities bearing disproportionate impacts
  • Accountability for drivers who injure or kill cyclists
