"Scooters
Though not an encouraged means of transportation, certain types of scooters are allowed to traverse Black Rock City without needing a license. Small, stand-up (no seat), one-person style scooters, (e.g. Go-Peds) are allowed at Black Rock City. Some of these vehicles do have a trademark — a very distinctive, and to many, annoying sound. We encourage you to use an electric model, one with a muffler, or other style that does not have that loud "buzzzzzz". And remember, riders must obey the same speed and safety rules as other vehicle drivers."

If it's a stand up model, no license, but be prepared to have dirty looks constantly shot at you. Of course, if it's mutated beyond the whole "see, it looks like a surfboard" approach, you may get annoyed looks, followed by delighted smiles.
