DOT Random Drug Testing

Companies and organizations falling under DOT regulations are required to randomly test their employees for drugs and alcohol. Not only does this keep your DOT compliant, but random drug testing also helps deter your employees from misusing alcohol or doing drugs.

For the random alcohol test, it must be done prior, during or just after a driver has finished their safety-sensitive role (like driving the truck or flying the plane).

Random drug testing means all people in the “pool” have an equal shot at being selected for the test. Even if someone gets tested more often than others, in a truly random, scientifically-validated pool, being chosen is simply coincidence.

Test Smartly Labs can help you perform your DOT-mandated random drug testing on your employees. We offer several services to help ensure you’re choosing employees randomly and without any bias.

Not only can we run the drug test, but if you need help managing the selection of random testing through consortium services and pools, let us know.

How many get randomly tested?

The percentages of how many of your employees need randomly tested will vary by the DOT agency. Here’s the latest information from the DOT:
