A new analysis of California traffic fatality data has revealed that nearly half of the state’s road deaths in 2024 occurred in just three counties: Los Angeles, San Bernardino and Riverside.
The research, conducted by Omega Law Group, examined all 3,493 traffic fatalities recorded across California last year, breaking the deaths down by county, contributing behaviour and crash trends.
According to the findings, Los Angeles County alone recorded 744 fatalities in 2024 — nearly 20% of all statewide traffic deaths.
San Bernardino and Riverside counties followed closely behind, combining for a further 624 fatalities and pushing the three-county total to almost half of California’s entire fatality count.
Researchers say the data highlights how a relatively small number of high-risk regions are driving a disproportionate share of California’s roadway deaths.
“These numbers show that California’s traffic fatality crisis is not evenly spread across the state,” a spokesperson for Omega Law Group said.
“A small number of counties account for a very large percentage of deaths, and many of the contributing behaviours behind those crashes are both predictable and preventable.”
The study identified speeding as the leading contributing factor behind fatalities statewide, responsible for 965 deaths in 2024.
Alcohol impairment followed closely behind, contributing to 943 fatalities, while seatbelt non-use was linked to 737 deaths.
Researchers say these behaviours become particularly dangerous within heavily populated counties already facing dense commuter traffic, high pedestrian volumes and large roadway systems.
Los Angeles County stood out not only because of its overall fatality count, but also because of the complexity of its traffic environment, which combines high-speed freeways, urban congestion and substantial pedestrian activity.
The report also highlighted ongoing concerns around pedestrian fatalities, particularly in Los Angeles and Riverside counties.
According to the analysis, growing population density, increased traffic volumes and expanding suburban development are continuing to place additional pressure on California’s infrastructure.
Researchers argue that targeted interventions focused on high-risk counties could significantly reduce statewide fatalities.
The study suggests that stronger enforcement around speeding and impaired driving, combined with infrastructure improvements and public safety campaigns, could potentially reduce deaths by up to 30%.
“The important thing about this data is that it points toward where intervention could have the greatest impact,” the spokesperson added.
“When fatalities are concentrated so heavily within a relatively small number of counties, targeted safety measures become much more achievable and measurable.”
California continues to face major roadway safety challenges statewide, recording thousands of fatalities annually despite years of public awareness campaigns and enforcement efforts.
Researchers say understanding where and why these deaths are occurring is critical to improving long-term road safety outcomes.
The study analysed fatality data from NHTSA, DMV records, SafeTREC statistics and statewide crash behaviour trends across California.
