Consortium – Random Drug Testing

Enroll into a DOT Random Consortium Today:

Consortium and random drug testing programs are available for both:

DOT Employers & Owner Operators

Random drug testing programs are required for employers regulated by the United Stated Department of Transportation (DOT). If you are an owner operator, you are required to be enrolled into a consortium random drug testing program. Smaller DOT regulated employers may also elect to enroll into a consortium random drug testing program for easy compliance. Larger DOT regulated employers typically request a stand-alone DOT random testing program.

Consortium Random Testing Program

Consortium Random Drug Testing
  • This is a random drug testing pool that includes multiple companies. 
  • All regulated employees from all companies are enrolled into the consortium and eligible for selection for a random drug or alcohol test.
  • Once the required random testing percentages are met; all companies in the consortium are in compliance.  
  • Perfect for owner operators

Stand Alone Random Program

Drug Test
  • This is a random drug testing pool with employees from just one company.
  • Typically companies with over 12 employees elect to have a stand-alone random testing program.
  • For example, a company with 100 truck drivers will be required to test annually 25 drivers for drugs and annually 10 drivers for alcohol.
  • Random testing programs available for bus companies, private fleets and for hire carriers.

DOT Required Random Testing – Are you in Compliance?

For owner-operators two important steps must be taken to comply with the DOT FMCSA regulations for drug and alcohol testing:

  1. A pre-Employment test drug test with a negative result must be completed before operating a DOT covered commercial motor vehicle (CMV).
  2. You must enroll into a random testing consortium. Owner-operators are not permitted to manage random testing themselves.

US Drug Test Centers can assist owner operators in all areas of the United States, for immediate compliance with DOT FMCSA regulations for drug and alcohol testing, call US Drug Test Centers today at 866-566-0261.

Trucking Companies, Bus Companies, For Hire Carriers and Private Fleets
Both stand-alone random testing pools and consortium random testing pools are available for trucking companies, bus companies, for hire carriers and private fleets. Typically companies with over 20 drivers will elect to have a stand-alone random drug testing program. Compliance is more complicated for companies with more than one driver. US Drug Test Centers can simplify the process and help your company with a program that keeps you in compliance and out of trouble with the DOT so that you avoid fines and penalties.

NON-DOT Employers

Although not required by regulation, many non-DOT or non-regulated employers often conduct random drug and alcohol testing. These non-DOT programs can be customized and managed by US Drug Test Centers with drug and alcohol testing available in all areas of the United States.

Why conduct random drug testing? What’s the best tool employers have for deterring drug and alcohol use in the workplace? Random Testing. Here are just a few of the reasons why:

  • Saves lives and prevents injuries.
  • Helps employers identify workers with substance abuse issues and facilitate their treatment.
  • Allows employees to easily say no to illegal drug use. "No, thanks. They drug test at work.”
  • Reduces employer liability.
  • It is a fair way of testing

In most states random testing of DOT regulated employees and safety sensitive employees is legal and a sound business practice. In some states, there may be some prohibitions against random testing of non-safety sensitive employees. Compliance experts at US Drug Test Centers can assist with the legality of random drug and alcohol testing in your state.

Random testing is performed on an unannounced, unpredictable basis on employees whose identifying information (e.g., social security number or employee number) has been placed in a testing pool from which a scientifically arbitrary selection is made.  This selection is usually computer generated to ensure that it is indeed random and that each person in the workforce population has an equal chance of being selected for testing, regardless of whether that person was recently tested or not.  Because this type of testing has no advance notice, it serves as a deterrent.

US Drug Test Centers can assist employers with a customized random drug testing program fully managed with quick and easy implementation.

Caution to employers is advised. Many times we get an employer calling to ask for assistance with conducting a random test on an employee who the employer thinks is acting funny or perhaps using illicit drugs. It is important to note that this is not a random drug test; there is nothing random about it. This type of test is called a reasonable suspicion test and thus should be called a reasonable suspicion drug test.

States that limit random drug testing to safety sensitive workers include:

    • Alaska
    • California
    • District of Columbia
    • Maine

  • Massachusetts
  • Minnesota
  • Montana
  • New Jersey
  • West Virginia*

In West Virginia, mining employees random drug testing must cover at least 25% of employees and occur at least 4 times a year.

States or cities that prohibit random drug testing

  • San Francisco, CA
  • Boulder, CO
  • Rhode Island
  • Vermont

Random drug and alcohol testing should always be conducted with a scientifically valid method to select employees for testing. Unacceptable random selection practices include selecting numbers from a hat, rolling dice, throwing darts, picking cards, or selecting ping pong balls.
