CDL Hazardous Materials Practice Test

The presence of "rq" in the item description on shipping papers signifies that the amount of the hazardous material being shipped meets or exceeds the reportable quantity for that specific substance. When "rq" is included, it indicates that the carrier must report any spill of the material that exceeds that reportable threshold to the appropriate authorities. This requirement is in place to ensure proper handling and response to potential hazards, thereby enhancing safety for both the public and the environment.

Understanding this designation is crucial for anyone involved in the transportation of hazardous materials, as it highlights the need for vigilance regarding the handling and reporting of materials that could pose a risk if accidentally released.
