Motorcycle Laws Every California Biker Should Know

California has some of the most detailed motorcycle laws in the country. These rules govern safety equipment, riding behavior, insurance, and licensing, and violations can carry serious legal and financial consequences. If you were hurt in a crash, our Fresno motorcycle accident lawyers can help protect your rights and pursue the compensation you deserve.

Helmet Laws in California

California enforces a universal motorcycle helmet law. All riders and passengers must wear a compliant helmet at all times, regardless of age or experience. Under California Vehicle Code §27803:

• Riders must wear a helmet that meets U.S. Department of Transportation safety standards.
• The helmet must fit properly and remain securely fastened.
• Novelty or non-certified helmets violate the law.

Failure to wear a compliant helmet can result in fines and may significantly impact injury claims after an accident.

Lane Splitting Is Legal but Regulated

California remains the only state that explicitly allows lane splitting. However, legal does not mean unlimited. Lane splitting means riding between rows of stopped or moving vehicles in the same lane. According to guidance supported by the California Highway Patrol:

• Riders should lane split only when traffic moves slowly.
• Speed differentials should remain minimal.
• Unsafe or aggressive lane splitting may still lead to citations.

Law enforcement officers retain discretion to cite riders who split lanes in an unsafe manner, even though the practice itself is legal.

Motorcycle Licensing Requirements

California requires a valid motorcycle license or endorsement to legally operate a motorcycle. Key requirements include:

• A Class M1 license for all motorcycles
• A Class M2 license for motorized bicycles and mopeds
• Completion of a motorcycle skills test unless waived

Riders under 21 must complete a California Motorcyclist Safety Program course to qualify for a license. Operating without the proper license can lead to fines and complications after a crash.

Insurance Requirements for Motorcyclists

California law requires all motorcyclists to carry minimum liability insurance. Current minimum coverage includes:

• $15,000 for injury or death to one person
• $30,000 for injury or death to multiple people
• $5,000 for property damage

Riding without insurance can result in fines, vehicle impoundment, and personal liability for damages after an accident. 

Traffic Laws Apply Fully to Motorcycles

Motorcycles must follow the same traffic laws as passenger vehicles, with limited exceptions. Motorcyclists must:

• Obey all traffic signals and signs
• Use turn signals when changing lanes
• Yield the right of way when required
• Avoid reckless riding or excessive speed

Violations such as speeding or unsafe lane changes frequently appear in motorcycle accident investigations and insurance disputes.

Passenger and Equipment Rules

California places additional restrictions on carrying passengers and motorcycle equipment. Legal requirements include:

• A permanently attached passenger seat
• Footrests for passengers
• Functional mirrors and working brakes
• Properly maintained lighting and turn signals

Carrying a passenger without required equipment can result in citations and increase injury risk.

Cell Phone and Distraction Laws

California’s no-touch cell phone law applies equally to motorcyclists. Riders may not:

• Hold or touch a cell phone while riding
• Text, scroll, or tap a mounted device
• Use handheld electronic devices at stoplights

Only hands-free voice activation is permitted. Violations may result in fines and points on the rider’s driving record.

How a Fresno Motorcycle Accident Lawyer Can Help After a Crash

Motorcycle laws often play a decisive role after a crash. Insurance companies closely examine whether a rider followed helmet requirements, licensing rules, lane-splitting guidelines, and distracted driving laws. Even minor violations may lead insurers to dispute fault or reduce compensation. A Fresno motorcycle accident lawyer can help by:

• Investigating whether alleged violations actually apply under California law.
• Challenging unfair fault determinations tied to lane splitting or equipment issues.
• Preserving evidence before it disappears, including traffic camera footage.
• Working with accident reconstruction experts familiar with motorcycle dynamics.
• Calculating the full value of medical costs, lost income, and long-term injuries.
• Handling all insurance communications to protect the rider’s rights

Motorcyclists often face bias during claims and litigation. Legal representation helps ensure the law is applied accurately and fairly.
