New Mexico Administrative Code
Title 18 - TRANSPORTATION AND HIGHWAYS
Chapter 19 - MOTOR VEHICLE PROCEDURES, LICENSES, PERMITS
Part 8 - SIZE AND WEIGHT OF VEHICLES AND LOADS
Section 18.19.8.36 - OVERHEIGHT VEHICLES OR COMBINATIONS

A. Special permits may be issued for vehicles, combinations or loads in excess of the statutory limit for heights of 14 feet. When the substitution of a different type of trailer would make the vehicle or load 14 or less in height, then the load shall be considered reducible and such substitution shall be made.

B. If a special permit is requested for a height greater than 14 but less than 15 feet six inches, the applicant shall check the desired route for clearance of overhead structures such as traffic signals, wires, utility lines, bridges and overpasses.

C. If a special permit is requested for a height of 15 feet six inches or greater, a route survey is required. The applicant shall check the desired route and conduct a route survey for clearance of overhead structures such as traffic signals, wires, utility lines, bridges and overpasses.

D. Certification in writing from utility companies is required for a vehicle or load that exceeds a height of 18 feet. No person, other than the utility owner, shall move, lift or in any fashion displace an overhead wire.

E. Movements that will not clear highway construction, wires, utility lines, bridges, overpasses or other overhead structures shall be rerouted. Use of off-ramps or frontage roads to clear overhead and other obstacles is permitted, provided overall traffic flow is not adversely affected and traffic safety is not jeopardized.

F. A permittee shall protect all overhead wires, structures and roadside property. Any damage to these or to the roadway, pavement, road guards or shoulders shall be restored at the sole expense of the permittee.

G. The DOT may require a flagman or an escort to check all overhead clearances during a move. Such requirement shall be stated on the special permit.
