You'd think the driver would realize that he needed to let some air out of his tires before he tries to either backup or proceed. Might not work, but he should already know his vehicle was too tall to make it through once he got stuck!
I agree but you would think the township would identify these potential danger areas and place a warning bar as a gage well in advance of the bridge to totally avoid a disaster or a stupid driver that attempts to test the accuracy of the warning!
