As a truck driver with over 35 years and over 4 million miles of driving experience pulling 14 foot tall trailers. I have a couple of comments
1) Under paths/bridges are marked AT THEIR LOWEST POINT, I.E, on a curved bridge it will be at the lowest point of the curve where it it above road bed. The middle of the road normally has a ton of room. More then once in my over 4 million miles of driving I had to go thru the center of the road even if it meant crossing the center line (assuming that I could see that there was no oncoming traffic).

2) You can stop at most open, manned weight stations and go inside and as the scale person to measure the height of your trailer. they all have a device to measure over height vehicles.

3) keep a watch out for freshly paved roads. Sometimes the pave under the overpass/bridge but do not change the height sign. Most of the time they will either dig out the roadway before they pave or the will just not repave under the bridge.
