In comments filed with the U.S. Department of Transportation (DOT), Robert A. Hirsch, president of the Truckload Carriers Assn. (TCA), expressed concern with DOT’s recent notice on its drug-test results study.

The comments were filed in response to DOT’s request for comment on the feasibility and merits of employers and Medical Review Officers (MROs) reporting a driver’s positive drug test results to the state agency that issued the driver’s CDL.

According to Hirsch, TCA continues to clearly support the sharing of a driver’s past drug-test results to prevent substance-abusing drivers from skipping from carrier to carrier undetected.

“Should FMCSA conclude that the transmission of test-result information to the state licensing agencies is feasible and warranted, the responsibility for transmitting such information should be that of FMCSA, not industry,” Hirsch said.
