Before you are hired to work as a truck driver for any company, you will be required to pass a drug test. The purpose of this test is to ensure you are mentally and physically healthy and capable of handling a truck safely while on the road. All CDL drivers, whether they are full-time, part-time, backup, or international drivers, must take and pass a drug test to maintain CDL qualification. It’s important to note that in addition to the standard U.S. Department of Transportation drug testing applied to all CDL drivers, individual companies may also perform their own drug tests.

Substances Tested

The U.S. Department of Transportation drug testing procedure checks for a variety of drugs. There are five major classes of drugs that are tested for during the exam: phencyclidine (also called PCP), marijuana, cocaine, opiates, and amphetamines or methamphetamines. Alcohol testing is also a part of the drug testing procedure for CDL drivers.

Testing Procedure

DOT drug testing may occur at many different times. You will be tested prior to employment as a CDL driver. Drivers may also be tested for drugs following certain types of trucking accidents. Random testing may occur throughout each calendar year. Furthermore, if your employer has “reasonable suspicion” that you may be under the influence of drugs or alcohol or you are returning to duty after a reprimand or DOT violation, you may also be tested prior to work. Drug testing is performed via urine analysis, while alcohol testing is performed via breath analysis.
