This is a rigorous, source-backed look at Lyft-related safety in California using what is publicly available as of September 2025. Where 2024 California specific counts are not yet published, I say so directly and lean on the strongest adjacent indicators.

Key findings

• California did not publish a Lyft only crash count for 2024. The California Public Utilities Commission requires Transportation Network Companies to file Annual Reports that include collisions and other safety outcomes. A 2025 proposed decision directs TNCs to file public versions of their 2021 to 2024 Annual Reports, with limited redactions and 30 minute timestamp aggregation. That means more California level collision data is expected to enter the public record. California Public Utilities Commission
• Lyft’s latest U.S. Safety Transparency Report covers 2020 to 2022 and was released in July 2024. It documents 111 motor vehicle fatalities on the platform over those three years, 23 fatal physical assaults, and 2,651 reports in the five most serious sexual assault categories, across about 1.41 billion rides. Lyft reports these severe incidents occurred in about 0.0002% of rides. Contentful
• Per mile risk context. Lyft’s fatal crash rate per 100 million VMT was 0.68 in 2020, 0.86 in 2021, and 1.02 in 2022, compared with the U.S. national rates of 1.34, 1.38, and 1.33 in those years. Contentful
• California’s overall roadway risk improved into 2024. State traffic fatalities fell from 4,539 in 2022 to 4,061 in 2023 and NHTSA’s early estimate puts 2024 U.S. deaths at 39,345 with a fatality rate of 1.20 per 100 million VMT. This sets a favorable backdrop for rideshare risk. Office of Traffic Safety
• Rideshare exposure is concentrated in a few metros. About 64% of California TNC trips occur in Los Angeles, San Francisco, and San Diego counties, so most Lyft risk is urban and corridor specific. CommConveyance

2024 in California. What we know and what to watch

• The CPUC is moving toward publishing redacted public versions of TNC Annual Reports for 2021 to 2024, which include collision data. Once posted, California specific Lyft collision counts and rates can be computed and compared across counties and corridors. California Public Utilities Commission
• Lyft’s 2020 to 2022 U.S. pattern shows that the absolute number of fatal crashes rose during the pandemic era even as overall crash frequency fell, but Lyft’s fatality rate per mile remained below the national average. If California’s 2023 and 2024 roadway improvements hold, Lyft’s California risk in 2024 likely trended flat to down pending CPUC release. Contentful+2Office of Traffic Safety
• Expect differences between company counts and CPUC rollups. SFCTA’s audit of CPUC public files shows taxonomy mismatches between Uber and Lyft for collisions and other safety categories. The CPUC’s 2025 proposed decision acknowledges the strong public interest in disclosure and sets new formatting and aggregation rules, which should improve consistency. TNCs 2020

Where Lyft risk concentrates in California

• Urban arterials and downtown networks with high pickup and drop off activity in Los Angeles, San Francisco, and San Diego see the most exposure. This is where speed management, curb management, and turn phase protections deliver the highest payoff. CommConveyance
• Night and weekend periods are typically over represented in severe urban crashes systemwide, which aligns with rideshare demand peaks. The statewide decline in 2023 fatalities suggests enforcement and calmer traffic volumes helped. Office of Traffic Safety

Practical takeaways for agencies and firms in 2024 to 2025

• Prepare to align CPUC released collision counts with Vision Zero high injury networks in LA, SF, and SD to target curb design, pickup zones, signal timing, and left turn protection where rideshare activity is highest. CommConveyance
• Use Lyft’s rate framing, not just raw counts. When CPUC posts 2021 to 2024 tables, compute fatal and injury collisions per million VMT and per million trips by county to avoid misleading rank ordering by sheer volume. The Lyft report includes VMT based rates that can serve as a benchmark. Contentful
• Address driver work risk directly. Peer reviewed research in 2024 highlights elevated work related crash risk among rideshare drivers tied to night driving, fatigue, and distraction. Scale app nudges for breaks, speeding feedback, and hotspot alerts. California Public Utilities Commission

Methods and limitations

• Scope here uses Lyft’s U.S. safety report for 2020 to 2022 and California’s statewide road safety indicators for 2023 to 2024. Lyft has not published California only counts for 2024, and the CPUC has not yet posted public collision tables for 2024 Annual Reports. Contentful
• The SFCTA TNCs 2020 project demonstrates the categories the CPUC receives, including collisions, and reveals taxonomy differences that complicate direct company to company comparisons. Expect improved transparency as CPUC implements new disclosure guidance. TNCs 2020
