General Highway Requirements

TM 55-315

b. Packages of radioactive material labeled Radioactive Yellow-II or Radioactive Yellow-III must not be placed in

cars, motor vehicles, trailers, or other places closer than the distances shown in table 11-1 to an area or a dividing

partition between areas that may be continuously occupied by passengers, employees, or shipments of animals, nor

closer than the distances shown to any package containing undeveloped film (if so marked). If more than one of these

packages is present, the distance shall be computed based on the total transport index (the sum of the transport indexes

on the individual packages (49 CFR 177.842)).

11-7. General Highway Requirements (49 CFR 177.807, 177.810, 177-811, 177.817, 177.825, and 177.842)

a. Carriers shall report incidents involving hazardous materials to the Department of Transportation as required by

49 CFR 171.15 and 171.16.

b. Carriers shall be required to comply with regulations established and published under authority of State statutes or

municipal ordinances regarding the shipment of hazardous materials through any urban vehicular tunnel used for mass

transport.

c. Any carrier possessing an astray shipment of radioactive material shall:

(1) Inspect the package to ensure that it is in proper condition for transport.

(2) Forward it promptly to its destination, if known.

d. Motor carriers may not transport radioactive materials unless they are accompanied by shipping papers prepared

according to 49 CFR 172. 201 through 172.204 (chap 5).

e. A driver of a motor vehicle containing radioactive material, and each carrier using such a vehicle, shall ensure

that the required shipping papers are readily available to, and recognizable by, authorities in case of accident or

inspection. Specifically, the driver and carrier shall:

(1) Clearly distinguish the shipping papers, if the radioactive material is carried with shipping papers or other

papers of any kind, by either distinctly tabbing them or having them appear first. They shall be stored so that, when the

driver is at the vehicle's controls, the shipping papers are within his reach while he is restrained by the lap belt. The

papers must be readily visible to a person entering the driver's compartment or in a holder mounted inside the door on

the driver's side of the vehicle.

f. Persons should not remain unnecessarily inside a vehicle containing radioactive materials.

11-8. Loading and Unloading Requirements (49 CFR 177.834)

a. Any package or container not permanently attached to a motor vehicle that contains radioactive material must be

secured against movement within the vehicle on which it is being transported. This restraint must be sufficient for normal

transport conditions.

b. No hazardous material shall be loaded into or on, or unloaded from, any motor vehicle unless the handbrake is

securely set and all other reasonable precautions have been taken to prevent motion of the vehicle during loading or

unloading.

11-9. Shipments of Fissile Materials (49 CFR 177.842(f))

a. Each Fissile Class III shipment (para 2-17) must be transported according to one of the methods in 49 CFR 173.

457 (para 6-16). The transport controls must be adequate to assure that no Fissile Class III ship-
