Question about Dealer Tags

[CleanNeon98]

OK so we do most of our work in PA. The usual rule is that most of the time we swap our dealer plates from car to car about 10 times a day and usually dont bother putting them on to their right place, just somehow stick them in the back window, but sometimes especially on long trips, bumps and such make them fall down or out of their spot.

Would an officer upon pulling me over for example (for not having tags on the car because they fell or whatever), would I be able to show him the tag that fell inside of the car for example(with proper documentation taped to the back of it of couse) and be OK, or is it a violation no matter what the case is. Truth of the matter is I dont want to always carry screws in my back pocket because a lot of times I have 10+ hour days and it would be a pain in the ass (literally) every time I went to sit down to do some work, but if needed I will.

Thanks Sarge!

Im guessing your selling or transporting these cars and they are not cars your using for your own personal ride.

If thats the case I would screw the plate to a magnetic backing and put on trunk, or if the car is all plastic like most are clearly proping up in the rear window should be fine. BUT (note the big but) by law it has to be afixed to the car so if your stopped you could be summons.
