Traffic accidents happen every day across Southern California, changing lives in an instant. Crashes remain a major public health concern on public roadways throughout the region, from Coast Highway 101 in Encinitas to Interstate 5 through San Diego County.
In cooperation with the California Highway Patrol (CHP), the Statewide Integrated Traffic Records System (SWITRS) has published extensive data on auto accident rates in Southern California. By examining these figures, we can better understand the hazards drivers, pedestrians and cyclists face every day on our region’s roads.
Understanding local crash numbers
Southern California sees tens of thousands of reported traffic collisions each year. These incidents result in over 200 fatalities and thousands of reported injuries in 2023, the year with the most recent car accident data. The automobile accident statistics gathered by SWITRS show several notable patterns, including:
- Overall accident totals: Over 23,000 traffic crashes occurred in 2025 across San Diego County.
- Pedestrian and bicycle accidents: Some areas within the region see higher rates of pedestrian and bicycle accidents than others. Coastal corridors experience higher rates of these injuries due to heavy tourist foot traffic and shared bike lanes.
- Peak accident times: Researchers also identified the most likely times for crashes. Morning and evening commute hours see the highest concentration of multi-vehicle collisions.
Car accident fatalities in California have decreased every year since 2022 after a spike following the pandemic. To continue this trend, the state implemented the California Highway Safety Plan 2024 – 2026.
Common types of car crashes in California
Car crashes take many forms. Each one creates unique physical challenges for victims. According to statistics, some of the most commonly occurring car accidents in Southern California are:
- Speeding accidents
- Distracted driving accidents
- Failure to yield right-of-way
- Left turns
- Rear-end collisions
- Side-impact crashes, or T-bone crashes
High-density beach towns such as Encinitas see frequent foot traffic, making pedestrian strikes particularly dangerous. The same applies to cyclists, who face perils such as low visibility from drivers.
