 Due to their small wheels, motorized scooters are not typically safe for street use as even the smallest bumps can cause an accident.California requires that a person riding a motorized scooter on a street be 16 years of age or older, have a valid driver's license, be wearing a bicycle helmet, have no passengers, and otherwise follow the same rules of the road the same as cars do.The motorized scooter must have brakes, may not have handlebars raised above the operator's shoulders, and if ridden at night must have a headlight, a taillight, and side reflectors.
