DOT Drug Testing Services
National Drug Screening provides Department of Transportation (DOT) compliant drug and alcohol testing services and programs. Anyone designated in Department of Transportation (DOT) regulations as being a safety-sensitive employee, such as pilots, boat captains and truck drivers, is required to submit to drug and alcohol testing.
DOT drug testing is performed prior to hiring, and on a random basis once employed; random testing is for drugs and alcohol for most DOT agencies. In addition to pre-employment and random drug screening, a DOT drug test may be required for reasonable suspicion, post-accident, returning to duty after a period of absence, or a follow-up (such as to maintain an active status after returning to duty).
The Six Main DOT Industries that Require Drug & Alcohol Testing
There are six main job industry categories as defined in the Department of Transportation regulations as being safety-sensitive and therefore required to submit to DOT drug and alcohol testing. These are commonly called DOT agencies or modes of transportation.
- The first is the Aviation industry, or Federal Aviation Administration - FAA regulated employees, which include, but are not limited to air traffic controllers, aircraft maintenance personnel, aircraft dispatchers, flight instructors, flight crews, and flight attendants.
- The second category is Commercial Motor Carriers, or Federal Motor Carrier Safety Administration (FMCSA) employees. Some examples may include, but are not limited to vehicles required to display a DOT placard when transporting hazardous material, vehicles that carry over 16 passengers including the driver, and CDL (Commercial Driver’s License) holders who operate commercial motor vehicles that weigh a minimum of 26,001 Lbs.
- The third industry category is Maritime, which includes the United States Coast Guard (USCG), an agency of the United States Department of Homeland Security, as well as any crewmembers operating commercial vessels.
- The fourth category is the Pipeline industry, or members of the Pipeline and Hazardous Materials Safety Administration (PHMSA), which includes operations, maintenance and emergency response.
- The fifth category is the Railroad industry, or members of the Federal Railroad Administration (FRA), which includes Hours of Service Act (HSA) personnel, train and engine, and signal service or train dispatchers.
- Finally, the sixth category is the Transit industry, or members of the Federal Transit Administration (FTA), including vehicle mechanics, controllers, operators and armed security.
As a safety-sensitive employee, there are much more strict behavioral requirements than other industries of employment, and certain conduct is prohibited by DOT regulations. Employees are not permitted to use or even possess alcohol or illegal drugs while executing safety-sensitive functions, or while assigned to perform safety-sensitive tasks or roles. Employees are not permitted to consume alcohol within 4 hours of reporting for duty, or after receiving notice to report to duty. For flight attendants and flight crew members, it is 8 hours prior to reporting for service that they are prohibited from consuming alcohol.
Some of the restrictions are more common among other industries as well, like employees must not report for service, or remain working, when using a controlled substance, unless of course it is used in accordance with an authorized medical practitioner’s instructions. Obviously, if an employee is impaired by or under the influence of alcohol, or has used an illegal drug, then they are prohibited from reporting for duty, or remaining on duty.
Even if an employee has consumed alcohol the day prior to reporting for duty, if they still have a blood alcohol concentration (BAC) or breath alcohol level of 0.04 or more, or in some regulations 0.02 to 0.039, then they are not permitted to report for duty until their next scheduled service period. Employees cannot refuse to submit to any test for drugs or alcohol, or, of course, alter it in any way, or adulterate or substitute their specimen.
