San Diego sells itself on sunshine, beaches, and an easygoing pace of life. Its roads tell a different story. A new analysis from LendingTree puts San Diego at the top of California’s list for car accident rates and second in the entire country, ahead of Los Angeles, San Francisco, and every other major city in the state.
For a region that rarely sees snow or ice, that ranking raises an obvious question: why are San Diego drivers crashing so often? The answer is part data, part driver behavior, and part the way modern insurance analytics measure risk in the first place.
The Numbers Behind the Ranking
According to the study, San Diego logged 28.2 accidents for every 1,000 drivers. Only Raleigh, North Carolina, ranked higher among the nation’s 50 largest cities, at 29.1 accidents per 1,000 drivers.
California cities crowded the top of the list. As FOX 5 San Diego reported, the rest of the state’s showing looked like this:
- San Diego: 28.2 accidents per 1,000 drivers (2nd nationally)
- Los Angeles and San Francisco: 26.9 each (tied for 3rd)
- Sacramento: 25.6 (6th)
- Long Beach: 22.7 (8th)
- San Jose: 22.3 (9th)
Six of the ten worst cities in the country for accident rates are in California. That is not a San Diego problem alone; it is a statewide pattern with San Diego at the front of it.
How This Kind of Study Works
It helps to understand where these numbers come from. LendingTree’s driver studies are built from insurance shopping data, specifically the driving histories people report when they request car insurance quotes through its QuoteWizard platform. Researchers group those records by city and calculate incidents per 1,000 drivers.
That approach has real strengths. It captures fender benders and minor collisions that never show up in police reports, and it measures rates rather than raw totals, so large cities do not automatically look worse just because they have more people. It also has limits. It reflects drivers who were shopping for insurance during the study window, not every licensed driver in the city.
That is why it is worth comparing against other data sets. Allstate’s long-running America’s Best Drivers Report, which is based on claims data, ranked San Diego 117th out of 200 cities in 2025, with drivers averaging about 8.6 years between collisions, roughly 22.5% more often than the national average. Different method, same general conclusion: San Diego drivers crash more often than most of the country.
For the most detailed local picture, UC Berkeley’s Transportation Injury Mapping System (TIMS) lets anyone map police-reported collisions across California by street, year, and severity using the state’s official crash records.
Which Drivers Crash the Most?
The LendingTree data also broke accident rates down by age group and vehicle brand, and both results are worth a closer look.
Gen Z Leads, Millennials Trail
Gen Z drivers, defined in the report as ages 18 to 28, had the highest accident rate in the study at 33.1 per 1,000 drivers. Millennials posted the lowest rate of any generation at 14.8. Inexperience is the usual explanation, but smartphone use behind the wheel is a major factor for every age group. The National Highway Traffic Safety Administration identifies texting as one of the most dangerous forms of distraction because it takes a driver’s eyes, hands, and attention off the road at the same time.
Ram, Tesla, and Subaru Top the Brand List
By vehicle make, Ram drivers had the highest accident rate at 25.9 per 1,000, with Tesla and Subaru owners close behind. Pontiac drivers had the lowest rate of the 30 brands analyzed.
For a tech audience, the Tesla result stands out. Tesla vehicles are packed with driver assistance features, so why do their owners show up near the top? The study does not answer that directly, and brand rankings reflect who buys a vehicle and how they drive it as much as the vehicle itself. Quick acceleration, younger buyers, and overconfidence in semi-automated features are all plausible contributors. NHTSA is clear that today’s driver assistance technologies are designed to support an attentive driver, not replace one. No vehicle currently sold to consumers drives itself.
Why San Diego?
The study does not pin down a single cause, and San Diego residents have offered their own theories. One that came up repeatedly in local coverage is rain. San Diego gets so little of it that many drivers have limited experience on wet pavement, and the first storm of the season tends to bring a spike in crashes as oil and debris built up over dry months make roads slick.
Other likely factors include heavy freeway congestion on corridors like I-5, I-8, and I-15, a steady flow of tourists and military personnel unfamiliar with local roads, and the cross-border traffic that comes with sharing a busy international crossing with Tijuana.
The city has been working on the problem for years through its Vision Zero initiative, which launched in 2015 with a goal of eliminating traffic deaths and serious injuries through street redesigns, education, and enforcement. Statewide, the California Office of Traffic Safety funds enforcement and awareness campaigns targeting speeding, impaired driving, and distraction.
What a Crash Can Cost You
Accidents carry a financial cost that lingers long after the car is repaired. California drivers face some of the steepest insurance increases in the country after a crash, and in some cases premiums can rise more than 70%.
There are also legal obligations many drivers do not know about. California law requires you to file an SR-1 Report of Traffic Accident with the DMV within 10 days if anyone was injured or killed, or if property damage exceeded $1,000. That requirement applies regardless of who was at fault, and a police report or insurance claim does not satisfy it. Failing to file can lead to a suspended license.
These rules apply statewide, from San Diego to Sonoma County. When a crash involves injuries or a disputed insurance claim, many drivers find it worth talking with a local professional who knows California’s reporting deadlines and fault rules, such as a car accident attorney in Santa Rosa CA for drivers in the North Bay.
California also raised its minimum liability insurance limits in 2025 to $30,000 for injury or death of one person, $60,000 for injury or death of two or more people, and $15,000 for property damage. If your policy has not been reviewed in a while, it is worth confirming you meet the new minimums.
Practical Ways to Lower Your Risk
- Put the phone out of reach. Use your phone’s driving focus or do-not-disturb mode so notifications never tempt you.
- Slow down when it rains. The first rain after a dry spell is often the most dangerous. Increase following distance and brake earlier.
- Treat driver assistance as backup. Lane keeping and adaptive cruise control help, but they do not make you a passenger.
- Consider a dash cam. Video footage can settle fault disputes quickly and protect you in an insurance claim.
- Know your reporting duties. Save the SR-1 deadline in your phone now so you are not scrambling after a collision.
The Bottom Line
San Diego’s ranking is a reminder that great weather does not make for safe roads. The data points to a mix of distraction, inexperience, congestion, and drivers who are not ready for the rare rainy day. Whatever the cause, the takeaway for anyone driving in San Diego is the same: slow down, stay off your phone, and know what to do if a crash happens.
