What are the DOT drug testing requirements?
In 1991, the Omnibus Transportation Employee Testing Act created the following DOT Agencies which established drug and alcohol testing regulations to ensure that aircraft, trains, trucks, and buses were operated in a safe and responsible manner. As an employer or individual operating in a "Safety Sensitive" position, it is important to understand how these regulations impact you.
49 CFR Part 40 (commonly known as part 40) explains:
- How drug and alcohol testing is conducted
- Who is authorized to participate in the drug and alcohol testing program
- What employees must do before they may return to duty after a drug and/or alcohol violation
Each DOT Agency and the USCG have specific regulations that cover:
- The agency's prohibitions on drug and alcohol use
- Who is subject to comply with these regulations
- What type of testing is required
- When testing is required
- Consequences of non-compliance
FMCSA Drug and Alcohol Clearinghouse
The Federal Motor Carrier Safety Administration (FMCSA) amended its rule that would establish requirements for commercial driver's license employers and individuals with regards to the drug and alcohol clearing house which will take affect on January 6, 2020.
The FMCSA Clearinghouse is a secure online database that will allow employers, the FMCSA, State Driver Licensing Agencies, State Law Enforcement and individual CDL operators to access real time important information about a CDL Driver's drug and alcohol program violations and the ultimate goal of this database is to enhance safety on our Nation's public roadways.
For specific requirements, click the appropriate agency listed below in which you or your company is regulated by. Ask about our DOT Complete Compliance Package!
- Federal Aviation Administration (FAA) (14 CFR Part 120)
- United States Coast Guard (USCG) (46 CFR Parts 4,5 and 16)
- Federal Motor Carrier Safety Administration (FMCSA) (49 CFR Part 382)
- Pipeline and Hazardous Materials Safety Administration (PHMSA) (49 CFR Part 199)
- Federal Transit Administration (FTA) (49 CFR Part 655)
- Federal Railroad Administration (FRA) (49 CFR Part 219)
The Opioid Overdose Crisis
Every day, more than 130 people in the United States die after overdosing on opioids. The misuse of and addiction to opioids,including prescription pain relievers, heroin, and synthetic opioids such as fentanyl, is a serious national crisis that affects public health as well as social and economic welfare. The Centers for Disease Control and Prevention estimates that the total "economic burden" of prescription opioid misuse alone in the United States is $78.5 billion a year, including the costs of healthcare, lost productivity, addiction treatment, and criminal justice involvement.
- Roughly 21 to 29 percent of patients prescribed opioids for chronic pain misuse them.
- Between 8 and 12 percent develop an opioid use disorder.
- An estimated 4 to 6 percent who misuse prescription opioids transition to heroin.
- About 80 percent of people who use heroin first misused prescription opioids.
- Opioid overdoses increased 30 percent from July 2016 through September 2017 in 52 areas in 45 states.
- The Midwestern region saw opioid overdoses increase 70 percent from July 2016 through September 2017.
- Opioid overdoses in large cities increase by 54 percent in 16 states.
In the late 1990s, pharmaceutical companies reassured the medical community that patients would not become addicted to prescription opioid pain relievers, and healthcare providers began to prescribe them at greater rates. This subsequently led to widespread diversion and misuse of these medications before it became clear that these medications could indeed be highly addictive.3,4 Opioid overdose rates began to increase. In 2017, more than 47,000 Americans died as a result of an opioid overdose, including prescription opioids, heroin, and illicitly manufactured fentanyl, a powerful synthetic opioid.1That same year, an estimated 1.7 million people in the United States suffered from substance use disorders related to prescription opioid pain relievers, and 652,000 suffered from a heroin use disorder (not mutually exclusive)

AI Overview
Understanding DOT Drug Testing
DOT drug testing is a regulatory requirement enforced by the United States Department of Transportation to ensure that operators and safety-sensitive personnel in the transportation industry are compliant with federal drug-free workplace laws. This testing applies to millions of transportation professionals across various sectors, including aviation, trucking, railways, public transit, and pipelines.
Regulated Entities and Individuals
- Commercial Motor Vehicle Drivers: Includes anyone operating commercial vehicles that require a Commercial Driver’s License (CDL).
- Aviation Professionals: Applies to pilots, air traffic controllers, flight attendants, and aircraft maintenance personnel.
- Railroad Operators: Covers those who operate trains, prepare vehicles for service, and dispatch operations on the railway.
- Public Transit Workers: Encompasses bus drivers, mechanics, and any staff responsible for the safety of public transport operations.
- Pipeline Operators: Includes individuals involved in the operation and maintenance of pipeline facilities.
What Substances Are Tested?
The DOT drug testing program focuses on several major classes of drugs:
- Amphetamines and Methamphetamines
- Opiates, including heroin, codeine, and morphine
- Cocaine
- THC (tetrahydrocannabinol), found in marijuana
- Phencyclidine (PCP)
Procedure of DOT Drug Testing
The testing process is standardized to prevent tampering and ensure consistent results:
- Sample Collection: Urine samples are collected under strict conditions to ensure that they are not tampered with or substituted.
- Screening Tests: Initial screenings are conducted using immunoassay techniques. If a test is positive, further confirmation is required.
- Confirmation Tests: Confirmatory testing using more precise methods like Gas Chromatography/Mass Spectrometry (GC/MS) confirms the presence of specific drugs.
- Review Process: An MRO reviews confirmed positive results to determine if there is a legitimate medical explanation before reporting the result to the employer.
Implications of Non-Compliance
Non-compliance with DOT drug testing regulations can lead to significant consequences:
- Removal from Safety-Sensitive Duties: Employees testing positive are immediately removed from their safety-sensitive duties.
- Rehabilitation and Return-to-Duty Testing: Before returning to duty, employees must undergo an evaluation by a Substance Abuse Professional (SAP), complete any prescribed treatment, and have negative results on follow-up tests.
- Employment Consequences: Additional consequences may include job suspension, termination, or other disciplinary actions based on the employer’s policies.
DOT drug testing serves as a critical safeguard in the transportation industry, promoting a safe and responsible work environment while ensuring public safety and compliance with federal regulations.
