Ref No.: 14-0102

Dear Mr. Nelson:

This is a response to your May 12, 2014 letter requesting clarification of placarding requirements in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) and their relation to the Federal Motor Carrier Administration (FMCSA) regulations pertaining to hazmat endorsement requirements on Commercial Drivers’ Licenses (CDLs). Specifically, you ask if a carrier voluntarily placards a shipment containing bulk quantities of "UN3077, Environmentally hazardous substance, n.o.s. (lead, arsenic), 9, PG III, RQ10," must the driver hauling the material have a CDL with a hazmat endorsement.

Based on the information in your letter, bulk quantities of "UN3077, Environmentally hazardous substance, n.o.s. (lead, arsenic), 9, PG III" are appropriately described as Class 9 (Miscellaneous) hazardous materials. For Class 9 (Miscellaneous) hazardous materials, placards are not required to be displayed for domestic transportation, including that portion of international transportation, that occurs within the United States (see § 172.504(f)(9)).

In accordance with the FMCSA regulations, only drivers of vehicles transporting hazardous materials that are required to be placarded in accordance with Subpart F of Part 172 of the HMR must have a hazardous materials endorsement to their CDL (See § 383.93). Thus, a hazardous materials endorsement is not required for a driver transporting any quantity of Class 9 materials, even when placarded with Class 9 placards. It should be noted that the HMR does require that the driver must receive hazardous materials training (see §§ 177.800(c) and 177.816). This training must include general awareness, function-specific, safety, and security awareness training as specified in §172.704(a) of the HMR, as well as driver training in the applicable requirements of FMCSA Regulations (FMCSR; 49 CFR parts 390 through 397) and the procedures necessary for the safe operation of that motor vehicle.

Requirements for drivers to possess a CDL with a hazmat endorsement are maintained by FMCSA in 49 CFR Part 383. Questions regarding hazmat endorsements on CDLs should be directed to the Transportation Security Administration at 877-429-7746 or the appropriate FMCSA field office. A list of FMCSA field offices and contact information is available at:

I hope this information is helpful. If you have any more questions, please do not hesitate to contact this office.
