Commercial vehicle logo requirement?

There's no logo requirement on a commercial vehicle. On a Class 8 tractor--a semi--you need the license plate (base plate) and either a DOT number or "not for hire." You can put "not for hire" on a truck that is not used in commerce, like the tractor that pulls a race team's trailer. Everyone else must have a DOT number. But as far as logos go, you don't need to have a logo on your truck.
