DOT FMCSA Drug & Alcohol Testing Requirements

ProLab • June 28, 2024

The Federal Motor Carrier Safety Administration (FMCSA) requires employers of commercial motor vehicle (CMV) drivers to implement a comprehensive drug and alcohol testing program. This is to ensure the safety of the transportation industry by preventing drug and alcohol misuse among drivers.

What Must Be Done?

Drug and Alcohol Testing Policy in place. Employers must develop a written drug and alcohol testing policy and distribute it to all employees. The policy should outline testing procedures, consequences of testing positive, and employee rights.
Pre-Employment Drug Testing. All new hires must undergo a drug test before performing any safety-sensitive functions. A negative result is required to proceed with employment.
Random program. Employees are selected randomly to undergo testing. This must be done on an ongoing basis throughout the year. The annual minimum drug and alcohol random testing rates are established within FMCSA for 2024: 50% Random Drug Testing Rate; 10% Random Alcohol Testing Rate.
Training. If you employ drivers then supervisors must receive at least 60 minutes of training on recognizing the signs of drug use and 60 minutes on recognizing the signs of alcohol misuse.


Types of Tests

  • Pre-Employment Testing. Conducted before a new employee begins performing safety-sensitive duties.
  • Random Testing. Employees are selected randomly to undergo testing. This must be done on an ongoing basis throughout the year.
  • Reasonable Suspicion Testing. Conducted when a trained supervisor observes signs of drug or alcohol misuse.
  • Post-accident testing. Required after certain accidents. Drug Testing: Within 32 hours. Alcohol Testing: Within 2 hours, if not document the reason and conduct within 8 hours.
  • Return-to-Duty Testing. Required after a driver has violated the drug and alcohol testing regulations and has completed the necessary treatment.
  • Follow-up testing. Conducted after a driver returns to duty following a violation. The number and frequency of tests are determined by a Substance Abuse Professional (SAP). (Note: Do not confuse this with a driver returning to work after vacation!)
  • Random Consortium

Small fleet motor carriers can join a consortium to manage the random testing pool, ensuring a sufficient number of drivers are tested. That means you will be in the same pool with other employers. The Consortium/Third-Party Administrator (C/TPA) selects drivers randomly, ensuring the process is unbiased.

If you have a larger fleet, employers have the option to establish their own stand-alone pools for random drug and alcohol testing. This means that the employer manages their own random testing program internally, selecting employees for testing in a manner that ensures each employee has an equal chance of being tested each time selections are made. The selection process must be computerized to ensure randomness and fairness. This approach provides greater control and customization over the testing process, allowing employers to tailor their random testing procedures to their specific operational needs and schedules. Stand-alone pools also ensure that testing is conducted consistently and in compliance with FMCSA regulations, reinforcing the commitment to a drug- and alcohol-free workplace. However, managing a stand-alone pool requires a robust administrative framework to handle the computerized selection process, maintain accurate records, and ensure compliance with all regulatory requirements. You may consider a hiring Drug and Alcohol Testing Management Service or Drug and Alcohol Testing software to make compliance easier.

Record Keeping
  • Employers must maintain records of all test results, both positive and negative.
  • Maintain Custody and Control Form Copies
  • Documentation of supervisor training on drug and alcohol misuse must be kept.
  • A copy of the written drug and alcohol policy and proof of distribution to employees.
  • Employers must prepare an annual summary, called MIS report, of the results of their drug and alcohol testing program and submit it to the FMCSA when required.

The Department of Transportation (DOT), Federal Aviation Administration (FAA), Federal Railroad Administration (FRA), Federal Motor Carrier Safety Administration (FMCSA), and Federal Transit Administration (FTA) released a final ruling on updated procedures for Transportation Workplace Drug and Alcohol Testing Programs to include the addition of Oral Fluid Specimen Testing for Drugs. The rule amends the U.S. Department of Transportation's regulated industry drug testing program to include oral fluid testing. This additional methodology for drug testing will give employers a choice that will help combat employee cheating on urine drug tests and provide a less intrusive means of achieving the safety goals of the program. Effective June 1, 2023. Click the link to read the complete DOT rule

Reasonable Suspicion Test - if a trained supervisor or trained company official believes or suspects an employee is under the influence of drugs or alcohol this type of test is required. Supervisors must be trained in accordance with 49 CFR 382.603. A reasonable suspicion test can be conducted only when a trained supervisor observes specific signs of alcohol and/or drug use.
