I was wondering if one could fool these things by placing lots of other random numbers and letters in the area surrounding one’s license plate... some stick-on vinyl letters made in the license plate font.
Here’s a way to dodge the cameras:

That's likely to get you arrested, as the cameras take an actual photo.
Some Maryland teenagers were pranking adults they did not like by generating fake copies of their license plates using a computer, putting them on cars and then driving through red light cameras.
The authorities were freaking out as it was drawing so much attention to the unreliability of the system.
See my previous. I doubt it worked, but it’s the thought that counts.
But as long as your intent is not to deceive law enforcement (i.e. you are displaying the plate on the front vehicle in a far away state which doesn't require a front plate), they really don't care. It is reasonable revenue and free advertising for their state.
