1. Height. If the height of the trailer or the load appears to exceed 14
feet, a measurement may be needed in order to determine if an
oversize permit is required.

length of the tractor, trailer or combination appears to exceed 65 feet
and it is on a non-designated highway, a measurement may be
needed in order to determine if an oversize permit is required.
3. Width. If the trailer or the load extends beyond the maximum 8 feet 6
inch legal limit, an oversize permit is required if the load is nonreducible.
