HAZMAT INCIDENTS INVOLVING CRASHES OR TRAIN DERAILMENTS

Hazardous Materials Incidents Involving Vehicular Accidents or Derailments (monthly data)

Motor vehicle accidents or train derailments account for only a small portion of total number of hazardous materials incidents. However, their consequences are often the most severe.

NOTE: The current value is compared to the value from the same period in the previous year to account for seasonality.

Reporting requirements were extended to intrastate motor carriers on October 1, 1998, which may have affected data reported after this date.

Accident/derailment is a crash involving a motor vehicle or a derailment of a train.
