I lost my front plate in a mud hole last year and got pulled over driving back because the VA state troopers don't play. This was also a great job with traffic enforcement because while they were sitting on the side of the road with me, several cars drove by going 90+ but at least I also didn't have to pay anything in court since I got my license plate replaced immediately.Does your state require a front plate? In CA we're supposed to have one, but not often enforced.
For a long time I didn't have one, in CA usually it's more of an excuse to pull you over than anything in CA.
Doing a road trip some time ago over several states, when my wife and I were coming out of Utah, their state troopers were waiting near the state border and pull me over for not having a front license plate, and I wasn't even from their state!
If another state's trooper pulled me over under the pretext of a missing front plate, I would be willing to spend an inordinate amount of money on the most annoying lawyer I could find just to ruin that cop's day.
