Abstract

Virtually everything we own was transported by truck at some point. Around 3.5 million truck drivers haul almost 71% of U.S. freight. To ensure the safety of our roadways, the U.S. government requires all drivers to pass urinalysis drug screens. However, urinalysis drug screens are easily thwarted and some trucking companies use hair drug screens, a more stringent test. This research examines trucking industry data and finds about 300,000 truck drivers would be removed from their positions if forced to pass a hair drug test. Hair testing opponents argue that the test is biased against ethnic minority groups. Comparing urine and hair pass/fail rates for various ethnic groups, our results indicate ethnic groups are significantly different irrespective of testing procedure. Factors other than testing method seem to underlie ethnic group pass/fail rate differences.
