I had mine mounted like that on my old Dakota. When a cop pulled me over he told me that I was "destroying State property" and he could write me a ticket for that too. I don't know if it would have stuck or not. But I would be leary of it, just in case you run into a jerk of a cop. He ended up giving me a warning for speeding, as he didn't know how fast I was going. Just saw a loud truck with a lumpy cam take of quickly.
