Understanding California’s Fault Laws in Car Accident Cases

California Fault Law Comparative Negligence Rule Car Accident Crash Laws Insurance Help Attorney Bank on Frank Sacramento California
What is California Fault Law?
California is a “fault” state for car accidents. This means that the person who caused the accident is responsible for paying for the damages. If you’re hurt in a car accident, you can seek compensation from the at-fault driver, their insurance company, or by filing a lawsuit. Figuring out who is at fault is very important because it directly affects how much money you can recover for your injuries.

What is California’s Pure Comparative Negligence Rule?
California uses a rule called pure comparative negligence, which means you can still get compensation even if you were partly at fault for the accident. However, the amount you receive will be reduced by your percentage of fault. For example, if you were 20% at fault and your damages are $10,000, you would get $8,000. This rule helps make sure everyone is responsible for their part in the accident.

How is Fault Decided in California Car Accidents?
Fault is usually determined by looking at evidence such as:

Police reports: These include the officer’s notes and witness statements.
Traffic laws: Breaking rules like speeding or running a red light can show fault.
Witnesses: People who saw the accident can help explain what happened.
Expert opinions: Specialists may investigate the crash to figure out what went wrong.

Insurance companies also investigate accidents, but they often try to save money. This is why having a lawyer on your side can help ensure fault is properly assigned and that you get the compensation you deserve.

A major crash on Highway 50 in Sacramento caused significant traffic delays on Saturday morning, according to the California Highway Patrol. The accident happened around 10 a.m. on the eastbound side of the highway, just past Howe Avenue. Initially, three lanes were blocked, creating heavy congestion. A photo from the scene showed an Amazon delivery truck involved in the crash, coming to a stop across multiple lanes. CHP reported that the #1 and #2 lanes on eastbound Highway 50, along with one lane on the westbound side, would remain closed while crews worked to repair a damaged concrete barrier. The closures were expected to last about six hours. By 11:40 a.m., one of the eastbound lanes had reopened, helping to ease traffic. Caltrans confirmed that the crash had caused damage to the highway’s concrete barrier, requiring immediate repairs. Officials have not yet determined what led to the crash or whether anyone was injured. No further details have been released at this time. Drivers in the area were advised to expect delays and use alternate routes while crews continued their work.

If you’ve been injured in a car or motorcycle accident, you deserve fair compensation for your medical bills, lost wages, and pain and suffering. However, many accident victims unknowingly make mistakes that can weaken or even ruin their personal injury claims. To help you protect your rights and maximize your settlement, here are five common mistakes to avoid after an accident. 1. Not Seeking Medical Attention Right Away Even if you feel fine after an accident, it’s crucial to see a doctor as soon as possible. Some injuries—like whiplash or internal bleeding—may not show symptoms right away. If you delay treatment, the insurance company may argue that your injuries weren’t serious or weren’t caused by the accident. Always get checked out and follow your doctor’s recommendations. 2. Admitting Fault or Apologizing After an accident, emotions run high, and it’s natural to want to say, "I’m sorry." However, even a simple apology can be used against you. Insurance companies might twist your words to claim you admitted fault. Instead, stick to the facts when speaking to the other driver, police, or insurance adjusters. 3. Not Gathering Enough Evidence The more evidence you have, the stronger your claim. If you’re able to, take photos of the accident scene, vehicle damage, injuries, and road conditions. Get contact information from witnesses and request a copy of the police report. The more details you collect, the harder it is for the insurance company to dispute your claim. 4. Accepting the First Settlement Offer Insurance companies often offer quick settlements that are far lower than what you truly deserve. Once you accept an offer, you can’t go back and ask for more money—even if your medical bills keep piling up. Before agreeing to anything, consult with a personal injury attorney who can negotiate for the maximum compensation you’re entitled to. 5. Not Hiring an Experienced Personal Injury Attorney Navigating a personal injury claim on your own can be overwhelming, especially when dealing with insurance companies that try to minimize payouts. An experienced attorney will fight for your rights, handle negotiations, and ensure you don’t settle for less than you deserve. In cases involving serious injuries—like traumatic brain injuries, spinal damage, or wrongful death—having strong legal representation is essential. Injured in an Accident? We Can Help!

A tragic accident on the 15 Freeway in Lake Elsinore Sunday night left one person dead and two others injured after a pickup truck collided with a car on the rain-slicked roadway. According to the California Highway Patrol (CHP), the crash happened just before 9:30 p.m. on the northbound lanes of I-15, just south of Central Avenue. Authorities say one of the drivers involved called to report the accident, which involved a white Ford F-150 and a 2012 Toyota Scion TC. Investigators say the 54-year-old woman driving the Toyota, a resident of Hayward, lost control of her vehicle due to wet road conditions. As her car spun out, a 44-year-old Riverside man driving the Ford pickup was unable to stop in time and slammed into the sedan. The impact sent both vehicles off the road. Paramedics with the Riverside County Fire Department arrived and sadly pronounced a 52-year-old Lake Elsinore man, who was a passenger in the Toyota, dead at the scene. The Toyota’s driver suffered serious injuries but is expected to survive. A passenger in the pickup truck was also hospitalized with moderate injuries, while the pickup’s driver walked away unscathed. Authorities continue to investigate the crash, reminding drivers to be extra cautious when driving in rainy conditions.
