Well, the employers need to and must to ensure that all their CDL drivers who operate CMV’s go through proper DOT drug testing.
So with other words, all of their drivers including their part-time drivers, that transport 16+ passengers, carry hazardous cargo or drive vehicles that are greater than 26,000 GVWR, need to conduct DOT drug testing.
There is an exception to this rule where CMV’s drivers who operate only on private property that is never open to the public, do not have to be tested.
The Process of DOT Drug Testing
Each and every CDL driver and CMV’s operator is subject to regular as well as random DOT drug testing.
So once you are notified that you’ve been summoned for testing, you need to show up to the place where you are asked to give your urine sample.
If there are some issues with the sample, you might need to provide another sample (under supervision) that is no older than 3 hours.
