49 CFR Part 40 Foundations

Before you run a single DOT collection, you need to understand the regulation behind it. This free course walks through the major requirements and core concepts of 49 CFR Part 40 in plain English — how the program is built, who the players are, what gets tested, and what happens at every step — so the hands-on collector training actually makes sense.

The foundation every DOT collector, DER, and C/TPA starts with

49 CFR Part 40 provides the common procedural framework for DOT drug and alcohol testing. It works together with the applicable DOT agency regulation — or, for the Coast Guard, its own rules — which determine who is covered, when testing is required, and other program-specific requirements. This course explains it from the ground up: the structure, the vocabulary, and the end-to-end process. Whether you’re working toward a collector qualification or you just need to understand how the program actually works, this is where you start on solid ground — free, and at your own pace.

Get qualified

When you’re ready to perform DOT collections, the foundations carry straight into a collector or BAT qualification.

The regulation shouldn’t sit behind a paywall

Everyone in DOT testing — collectors, DERs, safety managers, C/TPA staff — needs to understand Part 40. Charging for the fundamentals just leaves people guessing, and a program built on guesswork is one that falls apart at audit. So we publish the full foundations free: no signup, no email wall, no payment.

If your work later calls for a formal collector qualification, that’s where a live proficiency demonstration comes in — but the knowledge itself should be free. So it is.

Part 40 Foundations — questions

Is this really free?

Yes — the entire 12-chapter Part 40 course is free to read, with no account, no email wall, and no payment. We mean it.

Is this the collector qualification?

No. This is the foundational knowledge. Each role then has its own qualification requirements on top of the knowledge: urine collectors complete qualification training plus five consecutive error-free mock collections (§40.33); oral fluid collectors complete device-specific qualification training plus five consecutive error-free mock collections for each device they will use (§40.35); BATs complete qualification training plus seven consecutive error-free mock tests (§40.213). Note that DOT-regulated oral fluid collections cannot be performed until two HHS-certified oral fluid laboratories exist — training may be completed in advance. The foundations carry straight into that — see the DOT Urine Collector, BAT, and Oral Fluid qualifications.

Who should take it?

Anyone who needs to understand DOT drug & alcohol testing — aspiring and current collectors, Designated Employer Representatives (DERs), C/TPA staff, safety and HR managers, and business owners entering the industry.

Do I get a certificate?

The foundations course is free educational study. If you need documented, documented training and qualification records for a file, that comes with our qualification programs and compliance certificates.

How current is it?

The course reflects 49 CFR Part 40 including recent updates such as oral fluid testing. Regulations change — always confirm against the current text at ecfr.gov before relying on it operationally.
