Riding by the Rules Is Your Best Protection
Knowing the motorcycle rules keeps you from getting ticketed, and it makes you a safer rider. It also matters if you’re ever hurt: after a crash, an insurer will look closely at whether you were licensed, insured, and riding within the law, because a rider who broke a rule is easier to blame.
You can’t control how other drivers behave. What you can do is know the law, ride defensively, and assume drivers may not see you. The key areas every San Mateo rider should know are:
Getting and keeping the right motorcycle license
Carrying insurance and reporting crashes to the DMV
Lane splitting, and when it's safe to do it
California's helmet requirement for every rider and passenger
If a driver hits you while you’re riding by the rules, the law is on your side. The consultation is free, and you pay nothing unless we win.
A Rider's Checklist for Staying Street-Legal
Hold the right license class.
Motorcycles require a Class M1 license; mopeds and motorized bicycles require a Class M2. A regular driver’s license doesn’t cover either.
Start with a permit if you're under 21.
Younger riders begin with a learner’s permit and must take a motorcycle safety course before they’re licensed.
Carry motorcycle insurance.
Your bike needs its own liability coverage, and extra coverage for your own injuries is strongly worth considering.
Report qualifying crashes to the DMV yourself.
A police report doesn’t count. The DMV expects a report from you when a crash causes injury or significant property damage.
Lane split only when traffic is slow or stopped.
Riding between lanes is legal in California, but doing it at speed is dangerous and can hurt your claim.
Wear a fastened, DOT-certified helmet on every ride.
The rule applies to you and your passenger, whatever your age or experience.
Why Coverage Matters as Much as the Rules
The at-fault driver's liability insurance
Usually the first source of payment for your medical bills, lost income, and pain and suffering.
Your uninsured/underinsured motorist coverage
Optional, but strongly recommended. A minimum liability policy may not cover even a short stay in intensive care, let alone a long recovery.
A claim even if you made a mistake
Under California’s pure comparative negligence rule, a rider found partly at fault still recovers, reduced by their share of the blame.
Your bike and gear
Repair or replacement of your motorcycle, helmet, and riding gear damaged in the crash.
How the Rules of the Road Shape a Motorcycle Claim
After a crash, fault usually comes down to one question: who didn’t do what the traffic laws required? We compare the driver’s conduct with those rules, whether it was failing to yield, turning across your path, or changing lanes without looking, and we show the insurer where the law puts responsibility.
We also make sure your own compliance is documented. Your license, insurance, helmet, and the way you were riding all answer the questions an adjuster will ask. When a police report gets the rules wrong, particularly around lane splitting, we challenge it with the evidence: photos, witness accounts, camera footage, and the layout of the road.
And we look at your coverage early. If the driver who hit you has too little insurance, your own uninsured or underinsured motorist coverage may be what makes a full recovery possible.
California Motorcycle Rules at a Glance
Licensing
Riders must be at least 16 to apply for a motorcycle license. Riders under 21 start with a learner’s permit and must complete a motorcycle safety course; riders 21 and older must pass a written test and a motorcycle skills test. The state recommends the safety course for every rider.
Insurance and crash reporting
Motorcycle riders must carry their own liability insurance. Crashes involving injury or significant property damage must be reported to the DMV by the people involved, and failing to report can lead to a license suspension.
Lane splitting is legal
California allows riders to travel between lanes of traffic, sometimes called whitelining or stripe-riding. It should only be done when traffic is slow or stopped. Otherwise, riders follow the same speed limits, signs, and signals as everyone else.
Helmets are mandatory
Every rider and passenger must wear a fastened, properly fitting, DOT-certified helmet on public roads, regardless of age or insurance status.

San Mateo Motorcycle Traffic Law FAQs
Do I need a special license to ride a motorcycle in San Mateo?
Yes. A regular driver’s license isn’t enough. Motorcycles require a Class M1 license, and mopeds and motorized bicycles require a Class M2.
How old do I have to be to get a motorcycle license?
At least 16. Riders under 21 begin with a learner’s permit and must complete a motorcycle safety course before getting their license.
Is lane splitting legal?
Yes. California allows riders to travel between lanes. It’s safest when traffic is slow or stopped, and riding between lanes at speed can be extremely dangerous.
Do I have to report a motorcycle crash to the DMV if the police came?
Often, yes. The police don’t file the DMV report for you, and failing to report a qualifying crash can lead to a suspended license.
What insurance do I need as a rider?
Your motorcycle needs its own liability insurance. Coverage for your own injuries, such as uninsured/underinsured motorist coverage, isn’t required, but it’s strongly recommended.
Are the traffic laws different for motorcycles?
Mostly no. Riders follow the same speed limits, signs, and signals as drivers. Lane splitting, licensing, and the helmet requirement are the main differences.
Can I still recover if I broke a traffic rule when I was hit?
Possibly. Under California’s pure comparative negligence rule, your compensation is reduced by your share of fault, not taken away.
What does it cost to talk to you?
Nothing. The consultation is free, and if we take your case, you pay nothing unless we win.
