Car accidents in California stem from predictable yet preventable factors. This article examines the five most prevalent causes – distracted driving, speeding, DUIs, reckless driving, and poor road conditions – supported by state-specific data. Understanding the causes of car accidents in California is critical for prevention and protecting your legal rights. Learn how these issues contribute to collisions, impact personal injury claims, and what drivers can do to stay safe.
Every day, California’s highways and city streets buzz with millions of drivers, but this constant flow comes with risks. In 2022 alone, over 4,400 lives were lost in car accidents in California, many due to avoidable behaviors. Whether you’re navigating Los Angeles’s congested freeways or rural routes in the Central Valley, knowing the top causes of collisions can mean the difference between safety and catastrophe. Here’s what every driver should recognize – and how to respond if disaster strikes.
1. Distracted Driving
Distracted driving remains a leading cause of car accidents in California, contributing significantly to the state’s overall collisions, according to the California Office of Traffic Safety (OTS). Data also shows that approximately 73 percent of Californians identify distracted driving (primarily through texting or talking) as their biggest traffic safety concern.
Despite strict hands-free laws (Vehicle Code § 23123), drivers still text, scroll through apps, or adjust GPS systems while driving. A 2023 CHP report found that a driver’s eyes are off the road for 5 seconds when texting – enough time to travel the length of a football field at 55 mph.
California’s comparative negligence system reduces compensation if a plaintiff is even partially at fault. For example, if you were glancing at a map during a collision, insurers might argue shared liability. Keep your eyes on the road and reduce your risk of getting dragged into a complicated lawsuit, even if you had the right of way.
You can help prevent distracted driving by using voice-activated systems and pulling over for adjustments. Employers can enforce no-phone policies for commercial drivers, who are at a greater absolute risk of being involved in a car accident due to their accumulated hours of driving.
2. Speeding
Speeding was a factor in nearly a third of all national traffic fatalities in 2023. High-risk areas include Interstate 5 in Central California and Interstate 15 near Las Vegas, where speed limits exceed 70 mph. Speed reduces reaction time and magnifies crash force: a 40 mph crash is 4x deadlier than one at 25 mph.
Curvy coastal routes like Highway 1 and urban arterials with sudden stops (e.g., San Francisco’s Lombard Street) heighten risks, as it’s much harder to be an anticipatory driver when bends are treated like straightaways.
As for the legal impact, it’s important to remember that excessive speed is clear negligence, strengthening injury claims. If you’re the victim, however, you should note that insurers may dispute claims if you also exceed the speed limit.
3. Driving Under the Influence (DUI)
Alcohol-impaired driving remain one of the undisputed greatest threats to road safety. About a third of all traffic deaths in California involve alcohol, with hotspots like Sacramento and San Diego County. California’s legal BAC limit is 0.08%, but legal cannabis use complicates impairment metrics. Data shows that cannabis-related traffic accidents requiring treatment in emergency rooms grew by nearly 500 percent between 2010 and 2021.
With an active nightlife comes greater overall risks. Cities like West Hollywood and Fresno see spikes in DUIs during weekends and festivals, making roads less safe for drivers and pedestrians alike. Meanwhile, DUI convictions almost guarantee liability for the impaired driver, maximizing victims’ compensation, while also greatly increasing your liability as the offending driver. Take note: about one in five California drivers lack insurance, so ask your insurance provider about uninsured motorist coverage.
4. Reckless Driving
Reckless driving is defined as willful disregard for safety, persons, and property. Common behaviors include illegal lane changes on congested freeways (e.g., LA’s I-405) and “road rage” incidents, which surged in the post-pandemic years.
In addition to road rage and other forms of reckless driving, legal yet risky driving can still be dangerous – such as lane-splitting. Lane-splitting is not forbidden by California law, but only about half of residents know that, and many inexperienced or inattentive drivers fail to check their blind spots, and are more likely to miss a lane splitting motorist when changing lanes. Motorcycle riders in cities like San Jose need to take extra care to avoid traffic accidents.
If you’re worried about reckless drivers and irresponsible behavior on the road, consider installing a dashcam. Dashcam footage is critical to proving recklessness. California’s pure comparative negligence rule allows compensation even if victims share partial blame.
5. Poor Road Conditions
California’s aging roads and climate extremes create hazards. Potholes on routes like I-710 in Long Beach, inadequate lighting on rural highways, and landslide-prone areas (e.g., Big Sur’s Highway 1) contribute to many non-DUI collisions.
Under California’s Government Code § 835, municipalities may be liable for unaddressed hazards. This means you can potentially hold your local government responsible for the circumstances leading to a traffic accident, and claim rightful compensation. However, claimants must prove officials knew about the issue, which can be a little tougher. If road conditions within your municipality are poor, be sure to ask your personal injury lawyer about government liability.
What to Do After a Car Accident in California

Report to Authorities
File a CHP or local police report within 24 hours.
Seek Medical Care
Some injuries (e.g., whiplash) manifest hours later.
