Electric Scooter Laws in California: Helmets, Speed, and Equipment

Electric scooter laws in California treat these devices as “motorized scooters” under the Vehicle Code, with the main rules set out in California Vehicle Code Section 21235. You need a driver’s license or instruction permit to ride, your top speed is capped at 15 miles per hour, sidewalks are off-limits, and riders under 18 must wear a helmet. Registration and insurance aren’t required, but cities can add their own restrictions on top of state law.

Who Can Legally Ride

You must hold a valid California driver’s license or instruction permit to operate a motorized scooter on public roads.¹ The DMV confirms that any class of license works.² Because California issues instruction permits starting at 15½, that becomes the practical minimum age. The statute itself doesn’t set an age; the license requirement does.

A motorized scooter is defined as a two-wheeled device with handlebars, a floorboard or a seat with footrests, and a motor.³ Motorcycles, motor-driven cycles, and mopeds are excluded and fall under different rules.

Helmets and Passengers

If you’re under 18, you must wear a properly fitted bicycle helmet that meets ASTM or CPSC standards.⁴ Riders 18 and older have no helmet requirement under state law.

Passengers are never allowed. Carrying anyone else on a motorized scooter is illegal at any age.¹

Speed Limit and Where You Can Ride

The statewide speed limit for motorized scooters is 15 miles per hour, and it applies everywhere: streets, bike lanes, and bike paths.⁵ It doesn’t matter what the road is posted at. Your scooter is capped at 15.

Where you can ride depends on the posted speed of the road:

On roads with a limit of 25 mph or less, you can ride in the roadway, a bike lane, or a bike path.
On roads with a limit over 25 mph, you can only ride in a Class II (striped bike lane) or Class IV (separated bikeway) facility. The general traffic lane is off-limits.¹
Local ordinances can extend scooter access to the roadway on streets posted up to 35 mph. Check the rules where you ride.¹

When traffic is moving faster than you are, stay as close to the right-hand curb or edge as is safely practical.⁶

Sidewalk riding is banned statewide. The one exception is crossing a sidewalk to enter or leave adjacent property, like a driveway or building entrance.¹

Required Equipment

Every motorized scooter must have a brake capable of locking the wheel and causing a skid on dry, level, clean pavement.¹

For riding after dark, you need three types of visibility equipment:⁷

A white front lamp visible from 300 feet ahead and from the sides. A lamp worn on your body counts.
A red rear reflector visible from 500 feet behind when hit by headlights. Reflective material on your body qualifies.
A white or yellow reflector on each side, visible from 200 feet to the front and rear.

Side reflectors are the requirement most riders miss. Many stock scooters don’t include them, so you may need to add stick-on reflectors yourself.

Other Rules Riders Trip Over

CVC 21235 covers a few more situations worth knowing:¹

You must keep at least one hand on the handlebars. Carrying a bag or package that makes that impossible is a violation.
Handlebars can’t be set so high that you have to raise your hands above shoulder level to steer.
You can’t hitch your scooter to another vehicle, and you can’t attach yourself to one.

Parking

State law prohibits leaving a motorized scooter lying on its side on a sidewalk or parking it in any position that blocks pedestrian traffic.¹ That’s the statewide baseline. Cities layer their own rules on top: San Francisco, for instance, requires upright parking in the sidewalk’s furniture zone, sets minimum distances from curb ramps, corners, and hydrants, and bans parking on narrow sidewalks. If you ride in a city with a rental scooter program, look up the local parking ordinance before you walk away from the scooter.

Riding Under the Influence

It’s illegal to operate a motorized scooter while under the influence of alcohol, drugs, or both under CVC 21221.5.⁸ A conviction carries a fine of up to $250.

The mechanics differ from a standard DUI. California’s implied consent law doesn’t apply, so you aren’t automatically required to submit to a blood or breath test. The statute does give the arrested rider the right to request a chemical test, and if you request one, the officer must have it performed.⁸ That provision exists so a sober rider can prove it.

The fine is small, but if you cause a crash while impaired, any liability protection from a rental company’s user agreement is likely voided, and an impairment finding will cut into what you can recover from another at-fault party.

Registration and Insurance

Motorized scooters don’t need to be registered with the DMV, and California doesn’t require riders to carry liability insurance.² The trade-off: if you injure someone or damage property, you’re personally on the hook. Rental companies like Lime provide limited third-party liability coverage, but the amounts are minimal and none of it covers your own injuries. If you ride regularly, ask whether your auto or renters policy covers scooter-related liability. Many don’t.
