Mapping Large Truck Rollovers

Mapping Large Truck Rollovers:  Identification and Mitigation Through Spatial Data Analysis



Rollover Crash Prevention

The Federal Motor Carrier Safety Administration (FMCSA), in association with the Pipeline and Hazardous Materials Safety Administration (PHMSA) and industry partners, created this tool as a training aid for commercial drivers of cargo tank motor vehicles transporting hazardous materials.

This training video covers the four approaches to reducing cargo tank truck rollovers: vehicle design and performance, load effects, highway factors and driver factors. The main focus however, is on the driver, since statistically; drivers are ten times more likely to be the cause of the rollover than any of the other factors. With this video, we hope to improve and enhance the consciousness of cargo tank motor vehicle drivers and the hazardous materials industry about common driving errors and to provide valuable driving information. Fleet safety managers are encouraged to use this video to supplement their driver training programs, as this information offers preventive measures that cargo tank motor vehicle drivers can take to help avoid a rollover crash. 

The interviews, ideas, and suggestions on this video were created at the request of the cargo tank motor vehicle industry. The video clips show examples of driver errors that we hope will serve to motivate cargo tank motor vehicle drivers to become safer drivers and thereby avoid dangerous driving situations.

Accident Reporting Agencies

In addition to recording the DOT recordable crashes, many states have requirements for reporting a crash. The threshold for reporting is different from FMCSA requirements in many instances. To insure that you are in compliance with all accident requirements, we are providing the agency that crashes must be reported to without providing information on the amounts. To insure you are in compliance following a crash, we recommend that you contact these agencies to determine if a accident report to that jurisdiction is required. Accident Reporting Agencies
