California has one of the most progressive legislations about personal mobility devices, which includes electric skateboards and e-scooters. According to California law AB-6904, it's legal to ride an electric skateboard on roads with a speed limit under 35 mph. You need to wear a helmet and have a headlight and reflectors (which can be attached to the rider or to the board). There is also a limit speed of 15 mph.
