Common Causes of Car Accidents in California and What They Mean for Your Claim
Wondering what really causes most crashes on California roads? The Wilshire Law Firm team breaks down the common causes so you understand your options. Want to know if you may have a claim? Our free case review is available 24/7, and there are no fees unless you get paid.

Distracted Driving
Was the other driver looking at their phone instead of the road?
Distracted driving is one of the most common causes of car accidents in California and often points directly to driver negligence. Distraction includes texting, scrolling, eating, adjusting navigation, or reaching for an object. Under California Vehicle Code §23123 and §23123.5, using a handheld phone or texting while driving is generally unlawful, and a violation can help support a negligence claim. If you were hurt by a distracted driver, a free case review can help you understand your options.
Speeding
Did the crash happen because someone was driving too fast to stop in time?
Speeding is a leading cause of car accidents because it reduces reaction time and increases the force of impact. California’s “basic speed law” under Vehicle Code §22350 generally prohibits driving faster than is safe for current conditions, even when a driver is under the posted limit. Excessive speed in rain, traffic, or poor visibility may be strong evidence of fault. Our team can help you review what the available evidence suggests.
Drunk Driving
Were you hit by someone who had been drinking or using drugs?
Driving under the influence is a common and preventable cause of serious crashes. Under California Vehicle Code §23152, it is generally unlawful to drive with a blood alcohol concentration of 0.08% or higher, or while impaired by drugs. A DUI conviction can be significant in a related injury claim, and in some cases a bar or host may share responsibility. If a drunk driver injured you, a free case review may help clarify who could be held responsible.
Drowsy Driving
Could the other driver have fallen asleep or been too tired to react?
Drowsy driving is a frequently overlooked cause of car accidents that can be just as dangerous as impaired driving. Fatigue slows reaction time and can cause a driver to drift out of a lane or miss a stop entirely. Long-haul commuters and commercial drivers may be especially at risk. Because fatigue is hard to see, evidence like phone records, work logs, and witness accounts often matters, and our team can help you gather it.
Weather & Road Hazards
Did rain, fog, or a dangerous road surface play a role in your crash?
Poor weather and road hazards contribute to many California car accidents, but they rarely excuse a driver entirely. Drivers are generally expected to adjust for rain, fog, slick pavement, or debris, and failing to do so can still count as negligence. In some cases, a government entity responsible for road maintenance may share fault, which can involve shorter claim deadlines. A legal professional can help you sort out these more complex situations.
Vehicle Defects
What if the crash was caused by faulty brakes, tires, or a mechanical failure?
Vehicle defects such as faulty brakes, worn or defective tires, and steering failures are a less obvious cause of car accidents that can shift responsibility beyond the drivers. When a defective part causes a crash, a manufacturer or repair shop may potentially be held liable under California product liability principles. These claims can be technical and often require preserving the vehicle and parts as evidence. If you suspect a defect, a free case review can help you decide what to do next.
Proving Fault
How do you actually show who was responsible for the accident?
Proving fault in a California car accident generally means showing that another party was negligent and that their negligence caused your injuries. California follows a pure comparative fault rule, so you may still recover compensation even if you were partly at fault, with your award reduced by your share of responsibility. Most personal injury claims are subject to the two-year statute of limitations under Code of Civil Procedure §335.1, though exceptions can apply. Our team can help you review the deadlines that may affect your claim.
FAQs
Distracted driving is widely considered one of the most common causes of car accidents. It includes texting, phone use, eating, and other activities that take a driver’s attention off the road. Speeding and impaired driving are also leading contributors. The specific cause of any crash depends on the facts, and a legal professional can help you evaluate yours.
Yes, in most cases you can still recover compensation in California even if you were partly at fault. California uses a pure comparative fault system, which generally reduces your recovery by your percentage of responsibility rather than barring it entirely. A free case review can help you understand how this may apply to your situation.
Generally, you have two years from the date of the accident to file a personal injury lawsuit in California under Code of Civil Procedure §335.1. Claims involving a government entity often have much shorter deadlines, sometimes as little as six months. Because exceptions exist, it is wise to speak with a legal professional promptly.
Right after a car accident, prioritize safety and medical care, then document what happened if you are able. Move to a safe location, call 911, exchange information, take photos, and get names of witnesses. Avoid admitting fault or giving a recorded statement to the other insurer before speaking with a legal professional.
Yes, a defective car part can shift responsibility toward a manufacturer or repair shop. If faulty brakes, tires, or another component caused the crash, you may have a product liability claim in addition to or instead of a claim against another driver. Preserving the vehicle and parts as evidence is often important, and our team can help.
