I would solve this problem in the opposite way. Install some much lower barriers(eg 2.5m) which make it painfully apparent that you aren’t going to get anything other than a car under it.
A truck driver isn’t going to keep driving if the barrier is clearly at face height.

I think you’d eventually lose even that bet.
The Needles Underpass is 2.4 m high and yet it sure does catch a lot of flies!
