The Federal Motor Carrier Administration has declared a Kentucky-licensed truck driver, Benjamin Scott Brewer, an imminent hazard to public safety after a crash investigation revealed cases of falsified records.

Brewer is being ordered not to operate any commercial motor vehicle in interstate commerce for his involvement in a nine-vehicle, six-fatality crash that occurred on June 25 in Chattanooga, Tenn.

Eighteen people were involved in that wreck. Brewer's truck failed to stop before striking the other eight vehicles, which were stopped because of road construction.

An ongoing investigation by FMCSA found that Brewer had falsified his records-of-duty status in the days leading up to the crash. He reported being off duty from June 15 – 25, but the vehicle tracking system used by his employer, along with other records, shows that Brewer had been on-duty and driving on June 22, 23, and 24.

It was also found that Brewer omitted a past citation and crash from his June 16, 2015 employment application, which required him to list all accidents and convictions occurring in the past three years. On May 25, Brewer also tested positive for controlled substances following a court-ordered controlled substances test.

FMCSA saidit will continue to assist the National Transportation Safety Board with its investigation into the fatal accident.
