No title. Motorized bicycle. Signals not required, can use hand signals. Headlight required. Chopper guys can and do use hand signals. 30 mph, <50cc, < (thought) 2 bhp. REALLY technically, no helmet required b/c not a motorcycle, but not worth the ticket.
Go to the MO DMV website, print off the statue on Motorized Bicycles, and carry it with you. That's what Jeff. City told me after a local po po SERGEANT demonstrated his ignorance of the laws by telling me I needed plates and issued me a warning.
