11' 8" Truck-eating bridge in Durham, N.C.

[Crusty]

Permits aren't required for vehicles within standard size limits, but if oversize then the driver is required to have a permit with routing on it and usually those are arranged by the driver's dispatch office. Most of the vehicles in the first video were within standard limits but "permit not required" is no defense for careless vehicle operation. The driver in the second video is probably selling shoes now.

Vehicles carrying hazardous materials (propane for instance) are required to follow designated HazMat routes regardless of size, and a proposed day care center located along one (railroads are too) won't get a license to operate.
