Of course. Did you remove a speed governor that was originally installed to limit the top speed of a moped or add a speed governor that limits the top speed of a moped or motorcycle?
No, I never would do that without the permission of the DMV.
The nature of the modifications I was hinting at might require a possible change of a registration from commercial to passenger class. What should I know about such modifications?
Are you talking about a pick-up truck?
No, I'm not.
Are you talking about a van then?
No.
Let's talk about a car, for example. Is a modified car still in the commercial class?
You can register a car in the 'commercial' class if all the seats behind the driver are removed. Instead of the seats you must install a permanent box or permanent rack to carry cargo.
Ah, I see. Will the DMV examine the vehicle and put it in the correct class then?
