If you want to ride an electrically motorized board, you must be at least 16 years old.

If you're riding an electrically motorized board on public roads, bike paths, sidewalks, or trails, you must wear a bike helmet that fits well and is fastened correctly, following the standards in Section 21212.

If you're using an electrically motorized board on a highway at night, you need to have certain lights and reflectors. You must have a white light that lights up the road ahead and can be seen from 300 feet away, a red reflector at the back visible from 500 feet, and white or yellow reflectors on each side visible from 200 feet. Instead, you can wear a light or reflector that meets these visibility requirements.
