I was helping a friend move from North Carolina to Rhode Island a few years back and he rented a truck that was way too big. From NC to New Jersey we kept seeing "Truck Route" signs and they all referred to trucks that were still taller than our truck (I don't remember the height). So we started to pay less attention to the signs. Then Google Maps sent us into New York. We saw something about all trucks take some other road, but stuck with the route Google recommended. Then we saw a big "All trucks over X height take next right" sign and the height was like 2 feet lower than our truck. That started a whole separate adventure, but while there may be some kind of safe route thing in the US, there are plenty of routes that vary from state to state, and at least back then google maps didn't have a way to enter the height of your vehicle.
