Hazardous Materials (HM) - Reviews


Hazardous Material reviews are conducted to investigate potential safety violations or complaints or to respond to a carrier’s request for a change in safety rating. This module gives data for five fiscal or calendar years of reviews conducted on motor carriers that transport hazardous materials in interstate or intrastate commerce.

Through education, greater safety regulation awareness, and the enforcement effects of reviews, motor carriers will improve the safety of their commercial vehicle operations and reduce their involvement in crashes.
