Nothing too fancy, color may vary to compliment the truck, but it's the same on everything ... including a small one on my laptop.

edit:  Looking at everyone's I see one common thread:  They are on the truck door often with a DOT number.  Keep in mind (and I forget if this is just an Illinois thing or if it is DOT.  Check your state laws) if a law enforcement officer gets picky the name on the door must match EXACTLY the name on the title. That is why the "logo" portion of mine is curved and in recent installations if separated as far as possible from the "legal" part. I'm a proprietorship, not a corp. I've since changed it so the name matches exactly what the title says.
