DOT Random Drug Testing

If your organization falls under DOT regulations, you’re required to randomly test your employees for drugs and alcohol. Not only does this keep you DOT compliant, but random testing also helps prevent your employees from misusing alcohol or doing drugs.

Random alcohol test must occur during or immediately after a driver has finished their safety-sensitive role (like driving the truck or flying the plane).

Random drug testing requires all individuals in the “pool” have an equal chance of being selected. Even if someone gets tested more often than others, in a truly random, scientifically-validated pool, being chosen is truly a matter of chance.

Test Smartly Labs is here to perform your DOT-mandated random drug testing. We offer various services to ensure your selection is guaranteed-random without any bias.

We’re also here to help manage the selection of random testing through consortium services and pools. Contact us for details!
