A new study from the Trucking Alliance and the University of Central Arkansas uses hair drug testing results from Trucking Alliance member carriers to suggest that drivers actually use cocaine more than marijuana, and that hair testing would essentially double the number of drivers disqualified for drug use.
The report, spearheaded by Trucking Alliance Managing Director Lane Kidd, looks at data from urine testing from the Drug and Alcohol Clearinghouse in December 2020 and compares it to four years of Trucking Alliance urine and hair testing results to advocate for the FMCSA allowing hair testing in lieu of urine testing, and to allow hair tests into the Clearinghouse record.
