Here's how it works. A police vehicle is exempt in my state from towing. How does it work, prior to towing the plate is ran, info taken down. If it's a government or in my case an under cover vehicle then it would get a no tow designation amd be left alone. The plates were registered individually amd put in the system. When I was under I parked where ever I needed to do my job. Parking was tight as he'll too. Plus a handicap spot is good cover.
