No. 09-0120 Dear Mr. LaBreck: I This responds to your letter requesting clarification of the placarding requirements under the Hazardous Materials Regulations (HMR; 49 CPR Parts 171-180). Specifically, you ~sk whether a pickup truck towing a trailer is considered two separate transport vehicles for the purposes of placarding under the HMR. Your client intends to tr~sport less than 1 ,dp1 Ibs aggregate gross weight of non-toxic compressed gases in both the! pickup truck and t~e trailer where the total aggregate gross weight of cylinders in both cargo-¢arrying bodies exqeeds 1,001Ibs. I I As you are aware, § 171.8 of the HMR defines a transport vehicle as "a cargo-carryirlg vehicle such as an automobile, van, tractor, truck, semitrailer, tank car or railcar used\ for the transportation of cargo by any mode. Each cargo-carrying body {trailer, rail car, etc'tiS a separate transport vehicle." Additionally, you are aware that placards are not require' on a transport vehicle which contains less than 454 kg (I,OOllbs) aggregate gross weight, f I hazardous materials covered by table 2 of paragraph ( e) under § 172.504. In the scen~rio you describe, the pick-up truck and trailer are two separate transport vehicles each carrying less than 454 kg (l,OOllbs) of eligible hazardous materials. Therefore, neither the pick-up truck nor the trailer is required to be placarded in highway transportation. I trust this satisfies your inquiry. Please contact us if we can be of further assistance.
