While trucking companies acknowledge that hair tests show a much higher number of drivers with drug problems than conventional drug testing, most still don’t use this modern and efficient test.

C.R. England, a large national trucking company, found when it switched to hair tests for drugs that the positive rate for drivers shot up to from 2.8% to 11%. Both JB Hunt and Schneider are also using hair tests to determine drug use. Schneider found on a simultaneous urinalysis/hair test that 82 truck drivers tested positive on the urinalysis and 964 on the hair test. The difference is 882 drug users that are on our roads, slipping through the crack with a company that does not hair test for drugs.
