Signs don't work. Take the example of the 11 Foot 8 bridge in Durham. It's quite famous, has blinking lighted signs telling trucks they are over height, and they still run through it. It was raised, but there are still plenty that test the laws of physics.
There were a number of bridges like this in a city near where I grew up, they had pipes hanging down before the bridge in a windchime-type fashion. You try to go under the bridge, your truck ends up with gouges which is better than having the top peeled, I guess.
Even if you manage to keep the trucks away, you'll still have the jackasses pulling campers or driving uhauls and RVs that will pay zero attention to the height signs.
"But Google maps told me to go this way..."
Yep. The map can't be wrong!
I'm torn between everyone figuring out a way to get their bridges to at least 13' 6" or letting dumbasses sort themselves out of large vehicles.
