Substance checks for licensed professionals operating vehicles in commerce are a critical safety measure. These checks ensure that drivers are not impaired by substances that could negatively impact their judgment, reaction time, and overall ability to safely operate a vehicle. For example, a pre-employment check might be required before a driver can begin transporting goods across state lines.
These procedures protect public safety by mitigating the risk of accidents caused by driver impairment. A clear history of substance use monitoring helps maintain public trust in the transportation industry and demonstrates a commitment to responsible operations. The establishment of robust regulations over time reflects society’s growing awareness of the dangers of operating vehicles under the influence and the importance of a drug-free transportation workforce.
