"Helments must be worn, unless the vehicle has an enclosed cab."
I doubt a cop pulling you over would know though.
It's no longer a motorcycle in Maryland... it's an auto cycle. No helmet. And before that, it past muster as an "enclosed cab", no different than a Miata.
Those are the autocycle laws I linked to and quoted from. I would not have counted it as an enclosed cab though. Is there somewhere in writing where it specifically spells out what an enclosed cab is?
Just my daughter the Baltimore County police officer.
