Dear Mr. Buckner:

This responds to your April 6, 2009 request for clarification of the placarding requirements in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) and the commercial drivers license (CDL) requirements under 49 CFR 383.93. Specifically, you ask if the

§ 172.504(f)(9) placarding exception for Class 9 materials also excepts your drivers from the hazardous materials endorsement requirement of 49 CFR 383.93 of the Federal Motor Carrier Safety Regulations (FMCSRs).

The answer is yes. In accordance with § 172.504(f)(9), placarding is not required for Class 9 materials when shipped domestically. In accordance with the FMCSRs, 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. Thus, a hazardous materials endorsement is not required for a driver transporting Class 9 materials.

I hope this answers your inquiry.
