Vandeaver\nHaliburton HRD\n4375 S. Loop 1604 E.\nElmendorf, TX 78114\nReference No. 16-0166R\nDear Mr. Vandeaver:\nThis letter is in further response to your October 12, 2016, letter requesting clarification of the\nHazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to placarding. In\nyour letter, you describe a scenario in which a pickup truck is pulling a trailer containing\nhazardous material in an amount which requires placarding. Specifically, you ask whether the\nfront of the pickup truck may be placarded to satisfy the front placard requirement prescribed in\n§ 172.504(a).\nWe note that you did not specify whether the pickup truck in your scenario has a fifth wheel and\nwould be considered a “truck-tractor,” or has a traditional “ball and hitch” set up. The term\n“truck-tractor” is defined in 49 CFR 390.5 of the Federal Motor Carrier Safety Regulations\n(FMCSR) as “a self-propelled commercial motor vehicle designed and/or used primarily for\ndrawing other vehicles.” Section 172.516(b) of the HMR states that the required placarding of\nthe front of a motor vehicle may be on the front of a truck-tractor instead of or in addition to the\nplacarding on the front of the cargo body to which a truck-tractor is attached. Therefore, if the\npickup truck in your scenario is a truck-tractor, the required placarding of the front of a motor\nvehicle may be on the front of a truck-tractor instead of or in addition to the placarding on the\nfront of the cargo body to which a truck-tractor is attached.\n\n<<<PAGE 2>>>\n\nIf the pickup truck in your scenario is not a truck-tractor, the required placards must be displayed\non each side and each end of the trailer containing the hazardous materials.\nI hope this information is helpful. Please contact us if we can be of further assistance.\nSincerely,\nShane C.
