How to Set Up a Non-DOT Drug Testing Program for Your Workplace

Start With a Written Policy

Before you order a single test, put your drug testing policy in writing and distribute it to every employee. A defensible non-DOT program spells out: which roles are tested, when testing occurs (pre-employment, random, reasonable suspicion, post-accident), what substances are screened, and what happens after a non-negative result. Employers who skip this step are the ones who run into trouble when a termination gets challenged.

Decide Which Testing Types You Need

Pre-employment is the most common starting point — screen candidates after a conditional offer, before their first day. Random testing adds an ongoing deterrent for current employees, typically drawn on a schedule the employee can't predict. Reasonable suspicion testing lets a trained supervisor request a test when they observe specific, documented signs of possible impairment. Post-accident testing supports your incident response and, in many states, your workers' comp premium discount eligibility.

Choose Your Panel

Unlike DOT testing, non-DOT employers can choose their own panel. A standard 5-panel (marijuana, cocaine, opiates, PCP, amphetamines) covers the basics. A 10-panel adds barbiturates, benzodiazepines, methadone, methaqualone, and propoxyphene — common in safety-sensitive or higher-risk industries. Some employers also add an expanded opiates panel to catch prescription opioid misuse (oxycodone, hydrocodone, oxymorphone, hydromorphone).

Know Your State's Rules

Non-DOT drug testing is governed by employer policy and state law — and state law varies significantly. Some states require advance written notice, restrict marijuana testing for off-duty use, or limit when random testing is permissible. Check your state's requirements before finalizing your policy, especially if you operate in multiple states.

Use MRO Review for Any Non-Negative Result

Even outside DOT rules, routing non-negative results through a Medical Review Officer protects both you and the employee — an MRO verifies there isn't a legitimate medical explanation (a valid prescription, for example) before a result is reported to you as positive.

Getting Started

You don't need a long-term contract to begin. Create a free employer account, choose your panel, and order your first test — whether that's a single pre-employment screen or setting up an ongoing random testing pool for your whole team.
