Every year, thousands of people across Southern California are injured or killed in car accidents that could have been prevented. In areas like Rancho Cucamonga, San Bernardino, and Los Angeles County, the most common causes of these crashes come down to one thing: human behavior.
At Muhareb Law Group, we’ve seen firsthand how a moment of distraction or poor decision-making can result in devastating injuries and lifelong consequences. That’s why understanding the leading causes of car accidents isn’t just important — it’s essential for protecting yourself, your passengers, and your rights if something goes wrong.
1. Distracted Driving
Distracted driving is the #1 cause of car accidents nationwide — and it’s a growing problem in California. Whether it’s texting, eating, adjusting your GPS, or just letting your mind wander in traffic, any activity that takes your focus off the road puts everyone at risk.
According to state data, distracted driving plays a role in about 1 in 4 crashes. And the danger isn’t just theoretical: in 2022 alone, distracted driving led to 148 deaths in California — the highest of any single crash cause.
What you can do: Put your phone away, set your GPS before you drive, and avoid multitasking behind the wheel.
2. Speeding
Speed limits aren’t suggestions. They exist to give drivers enough time to react, stop safely, and maintain control. Unfortunately, speeding remains one of the most common — and deadliest — crash factors in Southern California.
Driving too fast increases the severity of impact and reduces your ability to respond to sudden obstacles. In 2021, over 1,500 people died in speeding-related crashes in California. Locally, counties like San Bernardino and Riverside continue to report high fatality rates linked to speed.
What you can do: Follow posted limits, especially in residential zones or areas with heavy pedestrian or cyclist traffic. Always slow down in bad weather or poor visibility.
3. Driving Under the Influence (Alcohol or Drugs)
Despite decades of public awareness, impaired driving remains a deadly threat on California roads. Alcohol, prescription medications, marijuana, and illegal drugs all affect your judgment, coordination, and reaction time.
In 2022, Los Angeles County alone recorded over 6,300 DUI-related injuries and deaths. Peak danger times include late-night hours and weekends — especially between midnight and 3 a.m.
What you can do: Don’t drive under the influence, and don’t ride with someone who is. Use a designated driver, rideshare, or stay put.
4. Reckless and Aggressive Driving
Tailgating, weaving through traffic, road rage, and ignoring traffic signals are all examples of reckless driving — and all too common on congested Southern California freeways. These behaviors often lead to rear-end, sideswipe, and high-speed collisions.
What you can do: Stay calm, give others space, and don’t escalate aggressive behavior. If someone is driving dangerously, increase your distance or pull over safely.
5. Driver Fatigue
Fatigue can impair driving just like alcohol. Studies show that being awake for 18+ hours can impact your ability to drive as much as a 0.05% blood alcohol level. Many fatigue-related crashes happen late at night or on long road trips.
What you can do: Get rest before driving, take breaks on long trips, and pull over if you start to nod off or zone out.
6. Improper Turns and Lane Changes
Unsafe lane changes and improper turns at intersections are among the top causes of injury crashes in California. These mistakes often happen when drivers fail to use turn signals, misjudge distances, or change lanes without checking blind spots.
What you can do: Signal early, check mirrors and blind spots, and never cut off another driver. At intersections, follow posted signs and obey right-of-way laws.
7. Running Red Lights and Stop Signs
Intersections are one of the most dangerous places on the road. Running a red light or stop sign can lead to T-bone collisions — which often cause serious injuries or fatalities due to the angle of impact.
What you can do: Always stop fully at stop signs, and never try to “beat” a red light. Yellow means slow down — not speed up.
8. Weather and Road Conditions
Rain, fog, and poor lighting all increase crash risk — especially when paired with speeding or distraction. Slick roads reduce traction, while fog or glare can limit visibility.
What you can do: Slow down, turn on your headlights, and leave extra distance between vehicles during bad weather.
9. Vehicle Maintenance Failures
Bald tires, worn brakes, faulty headlights, and other mechanical failures are frequent crash contributors. Tire blowouts or stalled vehicles on the freeway can quickly become multi-car pileups.
What you can do: Regularly inspect your tires, brakes, lights, and fluids. Don’t delay needed repairs — safety comes first.
10. Inexperienced or Young Drivers
Teenage drivers are statistically more likely to be involved in serious crashes, often due to inexperience, distraction, or peer pressure. In California, teen drivers have one of the highest crash rates per mile driven.
What you can do: Parents should set clear rules, limit night driving, and model good behavior. If you’re a young driver, take extra time to learn the rules and build confidence.
What to Do If You’re Involved in a Car Accident
Even the safest drivers can’t control the actions of others. If you or someone you love has been injured in a car accident caused by another driver’s negligence, you may be entitled to compensation for medical bills, lost wages, and pain and suffering.
An experienced car accident attorney can help you understand your options, deal with insurance companies, and fight for the recovery you deserve.
