Drug & Alcohol
Consortium
Enrollment
The Department of Transportation (DOT) requires every owner-operator and motor carrier subject to FMCSA regulations to be enrolled in a Drug and Alcohol Consortium — also known as a C/TPA (Consortium/Third-Party Administrator). This is not optional: operating without enrollment puts your authority at risk.
At Truckssistance, we make enrollment simple and affordable, with flexible 1-year and 2-year plans that keep you compliant year-round — along with DOT-compliant pre-employment drug and alcohol testing services.
Your federally required testing program
A Drug and Alcohol Consortium (C/TPA) is a third-party administrator that manages DOT-mandated drug and alcohol testing programs for motor carriers. When you enroll, you become part of a random testing pool and gain access to all required testing services.
Random testing pool — FMCSA-compliant random selection throughout the year
Record keeping — All test results and program records maintained on your behalf
MRO services — Medical Review Officer review of all laboratory results
Annual reporting — Management Information System (MIS) reports as required by DOT
DOT enrollment is mandatory for
Owner-operators who operate under their own authority and have no employees
Motor carriers with CDL drivers in safety-sensitive positions
Any carrier subject to FMCSA regulations under 49 CFR Part 382
Carriers applying for or maintaining operating authority (MC Number)
Operating without consortium enrollment can result in fines, failed safety audits, and out-of-service orders.
Three steps to full compliance
Enroll in the Consortium
Choose your 1-year or 2-year plan and complete enrollment. You'll be added to our DOT-compliant random testing pool immediately.
Complete Pre-Employment Test
If you're a new operator or hiring a new driver, a pre-employment drug and alcohol test is required before the driver can perform safety-sensitive duties.
Stay Compliant Year-Round
We handle random testing notifications, record keeping, and reporting — so you can focus on driving while we keep you compliant.
