In the realm of transportation and safety-sensitive roles, ensuring that employees are fully vetted before taking on their responsibilities is not just a regulatory requirement—it's a crucial step toward safeguarding everyone on the road. The U.S. Department of Transportation (DOT) has established rigorous guidelines to prevent safety risks associated with impaired or unqualified personnel. DOT pre-employment checks, including the DOT Drug and Alcohol history check and Clearinghouse queries, play a vital role in maintaining safety and compliance, ensuring that all necessary steps are taken before employees engage in safety-sensitive functions.
