Common Myths About Motorcycle Accident Liability in California

Common Myths About Motorcycle Accident Liability in California

Motorcycle accidents leave riders with painful injuries and even more painful questions. Many riders in California believe things about fault that simply are not true. These myths spread through riding groups, comment sections, and well-meaning friends. Believing them can cost an injured rider real money, or an entire case. If you were hurt and want answers about your own situation, the California personal injury lawyers from Kermani LLP can explain how these rules apply to your case.

Lane Splitting Always Puts the Rider at Fault

Lane splitting is legal in California, and it has been since 2017. Vehicle Code 21658.1 defines lane splitting as riding a two-wheeled motorcycle between rows of stopped or moving vehicles in the same lane. California is the only state that allows this on both moving and stopped traffic. So the act of riding between cars does not make a rider guilty of anything.

Fault still depends on how each person behaved. A rider who splits lanes at a reckless speed may share some blame. But a driver who swerves into the gap without checking a mirror, or who opens a door to block a rider, can be held responsible. Insurance adjusters sometimes lean on this myth to push riders into small settlements. Knowing the law helps you push back.

Riding Without a Helmet Kills Your Case

California does require helmets. Vehicle Code 27803 says every rider and passenger must wear one that meets safety standards. Skipping the helmet can bring a ticket, and it can affect your claim. What it cannot do is erase your right to compensation. Here is what the helmet rule really means for a case:

  • Helmets are required
  • Claims still survive
  • Fault gets shared
  • Injuries get compared

The helmet question only matters when it connects to the injury. If a driver ran a red light and broke your leg, your bare head has nothing to do with that harm. If you suffered a head injury, the insurer may argue a helmet would have reduced it, and your payout could shrink by some percentage. Either way, the driver who caused the crash still owes for the damage they caused.

Being Partly at Fault Means You Get Nothing

Some states cut off recovery once a victim passes a certain share of blame. California does not work that way. The state follows a rule called pure comparative negligence, which grew out of Civil Code 1714. That law says each person is responsible for harm caused by their own lack of care.

Under this rule, your compensation drops by your share of fault, but it never disappears. Say your losses total $100,000 and a jury finds you 30 percent at fault. You still collect $70,000. Even a rider found 80 percent at fault can recover 20 percent of their losses. This rule matters because insurers often exaggerate a rider’s share of blame to shrink the check.

The Police Report Settles Everything

Many riders assume the officer’s report is the final word on fault. It is not. A police report is one piece of evidence, and officers sometimes arrive after the crash, talk mainly to the driver, or carry the common bias that riders are risk-takers. Courts and insurers can weigh other proof, including:

  • Photos and video
  • Witness statements
  • Skid marks
  • Vehicle damage

If the report blames you unfairly, you can challenge it. Traffic camera footage, dash cams, phone records, and crash reconstruction often tell a different story. Acting fast matters here, because video gets deleted and witnesses forget details within weeks.

You Have Plenty of Time to File

California gives injured people a deadline, and it arrives faster than most riders expect. Code of Civil Procedure 335.1 sets a two-year limit for most personal injury lawsuits, counted from the date of the crash. Miss that window and the court will almost always throw out your case, no matter how strong it is.

Some deadlines are even shorter. If a government vehicle hit you, or a dangerous road condition caused the crash, you must file a claim with the agency within six months under Government Code 911.2. Waiting also weakens your proof. Medical records, repair bills, and witness memories all serve a case best when gathered early.

Know the Facts Before Accepting the Myths 

The pattern behind all five myths is the same: they assume the rider loses before the facts are even examined. California law does not share that assumption. It permits lane splitting, keeps claims alive despite helmet mistakes or shared blame, lets riders challenge flawed reports, and gives a clear window to act. What decides a motorcycle case is evidence and timing, not the stereotype that bikers bring crashes on themselves. Riders who learn how the rules actually work put themselves in a far stronger spot than those who accept the myths.
