Seeing More Test Refusals?

As more states legalize marijuana, a new federal report shows that the number of positive drug tests among commercial drivers fell last year compared to the year before, dropping from 57,597 in 2022 to 54,464 in 2023.

At the same time, however, the number of drivers who refused to be screened at all also increased by 39 percent.

The rise in refusals meant that even though there were fewer positive tests overall in 2023, the total number of recorded drug violations among truckers actually rose —to 68,229 in 2023 compared to 67,775 a year earlier.

The 2023 year-end report is now posted on the FMCSA Clearinghouse.
