In the US the type of transmission for the test does not matter. IN NC there is a seperate test for motocycles now. However for anything under so many thousand pounds other than the motocycle it is just one license no mater what you take the test in. Above that I think you get into the comercial license that lets you drive the tractor tralier type rigs.
The three wheel bikes (usually clled a trike) just need the regular drivers license.
Told you the hand signals were a thing back in 1966. Lots of cars on the road back then did not have electrical turn signals.
