Quick Answer
A DOT-compliant drug testing policy must cover: (1) scope of coverage, (2) prohibited substances, (3) testing triggers, (4) collection procedures, (5) MRO/SAP protocols, and (6) consequences. The most common compliance gap: using a collector who isn’t certified under 49 CFR §40.33.
Why Every DOT-Regulated Employer Needs a Written Policy
A DOT drug and alcohol testing policy isn’t optional. For FMCSA-regulated employers, 49 CFR §382.601 explicitly requires a written policy that is distributed to every covered employee. Other modal agencies have equivalent mandates: FRA §219.23, FAA 14 CFR Part 120, PHMSA §199.115, and FTA §655.15 all require a formal written program.
The policy requirement spans every DOT-regulated sector:
- Commercial motor vehicle operators (FMCSA — CDL holders, CDL-required routes)
- Transit workers (FTA — operators, maintenance, controllers on federally funded transit)
- Aviation employees (FAA — flight crew, maintenance, air traffic controllers)
- Pipeline workers (PHMSA — operations, maintenance, emergency response)
- Railroad employees (FRA — locomotive engineers, conductors, signal workers)
What happens if you don’t have a written policy? The FMCSA can issue a civil penalty of up to $16,000 per day for a violation of 49 CFR Part 382 — and the absence of a written policy is one of the first things an FMCSA compliance review checks. See our guide to what happens when an employer fails a DOT drug test audit for the full penalty schedule.

The 7 Required Policy Elements
A federally compliant DOT drug and alcohol testing policy must include all seven of the following elements. Missing even one is an audit finding.
Statement of Purpose and Scope
Identifies the company as a DOT-regulated employer, cites the applicable modal regulation (e.g., 49 CFR Part 382 for FMCSA), references 49 CFR Part 40 as the collection and testing standard, and lists the safety-sensitive positions covered by the policy.
Prohibited Conduct
Defines all prohibited conduct: alcohol at or above 0.04 BAC, presence of controlled substances (marijuana, cocaine, opiates, amphetamines, PCP, MDMA), on-duty use, and refusal to test. Must explicitly state that a positive marijuana result is a federal violation regardless of state law.
Testing Circumstances
Covers all six DOT-mandated testing triggers: pre-employment, random (with applicable minimum testing rate), reasonable suspicion, post-accident, return-to-duty, and follow-up. Random testing rates and selection methodology must be specified. For more on random programs, see our guide to DOT random drug testing.
Collection Procedures
States that all urine collections are conducted by a collector qualified under 49 CFR §40.33, using the Federal Custody and Control Form (CCF), via split-specimen collection (Bottle A primary / Bottle B split), and shipped to a SAMHSA-certified laboratory under chain-of-custody procedures. This section is where most audits find compliance gaps.
MRO Review and Reporting
Designates the Medical Review Officer (MRO) by name and contact information. Describes the MRO's role in reviewing all lab results, contacting employees regarding positive results, and reporting verified results to the Designated Employer Representative (DER).
SAP Referral and Return-to-Duty
Describes the process for removing a policy violator from safety-sensitive functions, referring the employee to a Substance Abuse Professional (SAP), and the conditions for return-to-duty — including the required return-to-duty test and follow-up testing schedule.
Employee Education and Supervisor Training
Requires distribution of written educational materials to all safety-sensitive employees (§382.601) and documents the supervisor training requirement: 60 minutes on alcohol misuse signs + 60 minutes on controlled substance use signs (§382.603). Signed acknowledgments from all covered employees must be retained.

Position / Title: _______________________________ Employee ID: ___________The Certified Collector Gap — The Compliance Issue Most Employers Miss
Here’s what most HR managers don’t know: having a perfect written policy isn’t enough. You can pass every written-policy audit check and still fail an inspection if your collector isn’t §40.33 qualified.
The assumption most employers make is that the clinic or collection site handles collector qualifications. In practice, many clinics use staff who haven’t completed the full §40.33 certification process. Under 49 CFR §40.33, a qualified collector must have:
- 1
Completed a DOT-approved collector training course covering all collection steps, documentation, and error correction procedures
- 2
Demonstrated proficiency through five consecutive error-free mock collections — covering the five required collection scenarios: standard, shy bladder, temperature failure, observed collection, and split-specimen
- 3
Received a qualification sign-off from an employer or C/TPA confirming demonstrated competency
Audit reality: A single collection performed by an unqualified collector is a regulatory violation under 49 CFR §40.1. Even if the collection was procedurally flawless and the result was negative, the fact that the collector lacked §40.33 qualifications makes that collection legally defective. In an FMCSA compliance review, this appears as a collection procedure violation — regardless of your written policy.
The fix is straightforward: verify your collector’s §40.33 credentials before any collection occurs. Ask for their training certificate, their mock collection records, and their qualification sign-off document. If they can’t produce all three, they are not §40.33 qualified.
If your company uses an in-house employee as a collector — or if you want to build that capability — Cedar & Crown’s $99 course covers all three requirements: the training course, the proficiency mock collections, and the employer qualification framework. The credential that survives an audit.

Frequently Asked Questions
What happens if we don't have a written DOT drug testing policy?
Under 49 CFR §382.601 (FMCSA), a written policy is a mandatory regulatory requirement — not a best practice. Without one, the FMCSA can issue civil penalties up to $16,000 per day. Other modal agencies (FRA, FAA, FTA, PHMSA) have equivalent requirements. An auditor finding no written policy is an immediate compliance violation that can result in out-of-service orders for covered employees.
Does the DOT drug testing policy need to be distributed to all employees?
Yes. 49 CFR §382.601 requires that every covered employer provide each safety-sensitive employee with educational materials explaining the employer's drug and alcohol testing program, including the policy itself. Employees must sign an acknowledgment of receipt. The policy must also be available to employees at any time upon request. Failure to document distribution is itself an audit finding.
Can we use our own employee as a DOT drug test collector?
Yes, provided that employee meets the certification requirements of 49 CFR §40.33: completion of a DOT-approved collector training course, demonstration of proficiency through five consecutive error-free mock collections, and a qualification sign-off from an employer or C/TPA. The employee may not collect from themselves or from anyone they directly supervise, as a conflict-of-interest restriction under 49 CFR §40.33(a) applies.
How often should we update our DOT drug testing policy?
Your policy must be reviewed and updated whenever DOT or your modal agency revises its regulations — for example, when FMCSA adjusts random testing rates or when DOT updates 49 CFR Part 40 procedures. At a minimum, review the policy annually. After any regulatory update, the revised policy must be redistributed to all covered employees with a fresh signed acknowledgment.
What's the difference between a DOT and a non-DOT drug testing policy?
A DOT drug testing policy is governed by 49 CFR Part 40 and the applicable modal agency regulation (FMCSA §382, FRA §219, FAA Part 120, etc.). It mandates specific testing triggers, a 5-panel SAMHSA-certified lab test, Medical Review Officer (MRO) review of all results, Federal CCF form usage, and a certified collector under §40.33. Non-DOT policies are employer-created, can vary in panel size and procedures, and carry no federal compliance penalty — but they don't satisfy DOT regulatory requirements for safety-sensitive employees.
