Motor Carrier Shipments

a. The rules, regulations, and methods pertaining to loading, blocking, and bracing motor

carrier shipment of IPE are limited to those published in freight classifications and tariffs.

(1) In general, these publications contain information pertinent to methods of

packaging, such as loose, skidded, boxed, or crated items.

(2) Specific guidance, such as that furnished by the AAR, governing the loading of

equipment on open and closed cars, is not provided by the Motor Carrier Industry.

(3) The application of the principles and recommended methods of the AAR

publications to the loading of motor carrier equipment will result in carrier acceptance, and

under the normal hazards of truck transportation, will provide damage-free movement.

b. Due to the variance in load limits, clearance, and restrictions established by regulatory

bodies, loading shall be accomplished taking cognizance of all limitations to be encountered on

the entire route. The best source of information concerning restrictions that may be involved is

the appropriate Military Traffic Management Command (MTMC) area office or the carrier

designated by that agency in the routing.

c. When IPE is loaded on motor carrier transportation units, the following requirements

shall be adhered to:
