Can 3 wheel vehicles be registered in Texas?

The Texas Attorney General tells us in opinion, KP- 0331, that three-wheeled, electric, low-speed vehicles is not a question to be resolved in an opinion.

What?! Digging in we see that the Attorney General opinion says maybe these vehicles already fit the definition of motorcycle, maybe not, it depends.

The solutions: legislation to add these vehicles to registration and title statutes.
