What exactly is a CDL drug testing?
Well, if you are planning to get a CDL (Common Driver’s License) in the United States, one of the important steps, apart from the one involving your driving skills, is a CDL drug testing. This test is meant to find any traces of alcohol, marijuana, cocaine or any other sensitive drugs which may ultimately result in the termination of your application for a CDL license. There are different norms laid down by the Federal Highway Administration or FHWA of the DOT (Department of Transportation). It is mandatory to pass these tests, as otherwise you won’t be able to drive any commercial vehicle in the United States.

The Rules and Procedures:
There are different rules laid down by DOT for the CDL drug testing. First of all, a CDL license is required by all of the commercial drivers and hence all of them need to pass the drug test. Though such a license is not required by the drivers who drive vehicles with weight more than 26000 pounds such as the fire department vehicles. The procedure of this testing is fairly simple. The authenticated labs collect the samples of breath and urines of the people who have applied for a Commercial Driver’s License. After the collection they check the samples for traces of THC or alcohol. If a positive test or traces of drugs are found in the sample, the same is reported back to the employer and the concerned authority. A lab must be authenticated by the DOT to carry out such examinations and hence there’s no use going elsewhere. In case of a positive result, the corresponding driver may refer to a Medical Review Officer (MRO) and after having a few sessions with him discussing the reasons for positive drug test, may again go for another test.

Testing situations:
Well, the sub-heading may seem vague to you, but this CDL drug testing is not carried out only at the pre-employment phase. Though, it must be mentioned here that this test is carried out under several situations some of which include, pre-employment test, post-accident test and return to duty and follow up tests. The post accident test, though, is something which is carried out very often and has the most strict regulations.
