DOT CONSORTIUM ENROLLMENT - Tassajara, CA

Random Drug & Alcohol Testing Program
FMCSA - FAA - USCG - FTA - FRA - PHMSA

All Random Test Fees Included


Our DOT Consortium Membership includes quarterly random selections, notifications by email & phone, testing site coordination, MIS reporting, and a Certificate of Compliance upon enrollment. Owner-operators DOT-regulated employers Certificate of Compliance.

  • We offer 1, 2 and 3 year memberships (multi-year discounts)
  • All random selection testing and testing fees included (no hidden costs)
  • MIS report at year-end and upon request
  • DER support, Clearinghouse assistance (FMCSA), DOT Physicals, MVR Reports & Supervisor Training

Why is a DOT Consortium Required?

Owner Operators- DOT requires all owner-operators to enroll in a consortium so they are included in a compliant random testing pool because they cannot randomly test themselves.

Small Employers-Some smaller companies may not have enough drivers or safety-sensitive employees to maintain their own statistically valid random pool. Therefore, by joining a consortium, they are combined with other companies to form a large pool that meets DOT testing requirements.

Large Employers-Larger fleets may manage their own random pool but often use a consortium/TPA to outsource the process, reduce administrative burden, and ensure strict compliance.

How Our DOT Consortium Works

Step 1: Enroll: Select a 1, 2, or 3 year membership and receive your Certificate of Compliance by email.

Quarterly Selections: We process our consortiums using a scientifically valid, computer-generated random draws each quarter.

Immediate Notifications: If selected, your DER receives email & phone notice with selection instructions.

Testing & Results: Visit the assigned testing center. ADT will manage CCFs, lab processing, and reporting.

MIS Reporting: Year-end and on-demand MIS reports included.

Included With Membership

  • All random selection test fees (drug & alcohol where applicable)
  • DER support & audit-ready documentation
  • Federal CCFs (5-part) for DOT drug tests
  • FMCSA Clearinghouse registration assistance
  • Policy templates (DOT Drug & Alcohol)

    DOT Consortium: Frequently Asked Questions

    What is a DOT Consortium (C/TPA) and who requires it?

    A consortium C/TPA acts as a service agent to manage parts or all of an employer's drug and alcohol testing program. This includes random testing and various compliance tasks as dictated by the 49 CFR part 40 regulations.

    Are random testing rates consistent, or can they vary?

    The DOT's random testing percentages can fluctuate annually depending on positivity rates. Despite any changes in random testing percentages, our consortium covers all DOT random testing costs.

    What occurs when selected for a random test?

    ADT informs the Designated Employer Representative (DER) or Owner Operator by email or phone, providing the nearest testing location and further instructions. The employee must proceed immediately to the testing center upon receiving the notification.

    What substances are screened in a DOT drug test?

    A DOT drug test evaluates for a DOT 5-panel urine as well as a breath alcohol test. All these tests must utilize a Federal Custody and Control Form and Federal Alcohol Testing Form.

    Can you assist during a DOT audit or inspection?
