I have never had an issue with driving with the doors off, the only law you need to check regarding this is with mirrors. Some states require there to be at least two mirrors. PA only requires one mirror in which can see at least 200ft behind the vehicle, which is taken care of by the rear view mirror. I still have the lange breakaway mirrors as I like to be able to see what is going on. For those cops that like to give us issues, I refer you to the sticker that is placed on your visor. It states that the top and DOORS are strictly on the Jeep to keep the elements out and not as a safety feature. This enables jeepers to take their doors off without breaking the law. If the doors were part of the structural integrity of the car, it would then be illegal. So if you get pulled over, politely show him this sticker right on the visor.
