Consortium – Random Drug Testing

Enroll into a DOT Random Consortium Today:

Consortium and random drug testing programs are available for both:

  • DOT Employers 
  • DOT Owner-Operators

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

Let's look at both consortium random testing and stand-alone random testing further.

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 in 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

  • 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 annually test 25 drivers for drugs and 10 drivers for alcohol
  • Random testing programs are 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 drug test with a negative result must be completed before operating a DOT covered commercial motor vehicle (CMV)
  2. You must enroll in 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 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.
