Instructions:

Indicate the hazardous materials placard ID number.

Definition:

The hazardous materials identification class being transported by the motor vehicle, as required by Federal/State regulations to be displayed on a placard, regardless of whether it was accurate or validly displayed.

Rationale:

The Federal Motor Carrier Safety Administration (FMCSA) devotes special attention to motor carriers that transport hazardous materials (HM), including calculating risk assessments, determining response methods, imposing tighter regulations and conducting compliance reviews on a higher percentage of HM carriers. Getting good data on crashes involving trucks carrying HM and whether HM are spilled during the crashes helps FMCSA focus law enforcement efforts.
