DOT Drug Testing

DOT Drug Test Requirements
 

The DOT provides the regulatory framework that employers operating under a particular DOT agency must adhere to, and DISA has been helping companies maintain DOT drug testing compliance since its inception. These regulations cover a wide range of companies and employees in safety-sensitive industries to ensure they're operating safely and responsibly.

Random selection

The DOT requires quarterly random selections where all employees have an equal opportunity to be selected under the program.

 

Reasonable cause suspicion

Reasonable 
Cause
 

Under DOT regulations, employers are required to be trained to detect employees who may be under the influence of drugs and/or alcohol while on the job.

Post-Accident Testing
 

When an employee is involved in an accident, regardless of whether they are the cause or not, they must submit to a drug and alcohol test.
 

Return to duty

Return-to-Duty (RTD) 
 

If an employee fails a drug or alcohol test, they must undergo return-to-duty testing before returning to their DOT job responsibilities. It is under direct supervision and must be unannounced for the first 12 months.

What To Do if an Employee Fails a DOT Drug Test

When a DOT-mandated employee in a safety-sensitive position fails a test, the employee must be immediately removed from their duties. Depending on their position, the industry they're in, and which company policies they're subject to, additional consequences like having their license suspended may occur.

To be eligible to return to their position, the employee will need to complete a return-to-duty process. This includes a treatment and education program with a DOT-qualified Substance Abuse Professional (SAP), follow-up evaluations, and more frequent follow-up drug testing that must result in a negative test.
