What is on the paper, and why
Domain weights are a direct count of the distinct, separately-stated provisions the source regulations themselves contain: the 4 indicator categories (physical, behavioral, speech, performance) 49 CFR 382.603 requires alcohol training to cover, the same 4 categories plus the additional chronic/withdrawal-effects observation named only on the drug side in 49 CFR 382.307(b), the 8 distinct provisions of 49 CFR 382.307(a) through (f) governing the testing procedure, and 8 supervisor/DER-relevant provisions drawn from 49 CFR Part 40 Subpart O (40.285, 40.293, 40.305, 40.307), which 49 CFR 382.605 points to for the referral and SAP process. Each domain weight is that count divided by the 25-unit total.
Questions people ask
Is this the real DOT Reasonable Suspicion exam?
No. These are practice questions written to the actual regulation or statute this topic comes from. There is no single official exam to compare against for this topic; this is preparation for the underlying compliance content, not a copy of anyone’s proprietary test.
Does passing this give me a card or certification?
No. This is not an OSHA Outreach course, an EPA certification exam, or an accredited food-safety exam. Compliance with this topic is generally your employer’s or organization’s own responsibility, based on the training they provide and the policies they maintain. This platform prepares you for the underlying content, not a substitute for that training.
How much can I practise before questions repeat?
1 complete paper of 50 questions each, drawn from 90 questions, before you see anything twice.
Do I need to pay or sign up?
You can start practicing and sit your first full paper without an account. Signing in is what lets us save your answers and track readiness by topic over time. Unlimited full papers, plus review, history, the exam plan and flashcards, are part of Practice Test Pro ($19.99/month or $143.93/year).
What is a passing score?
There is no single published passing percentage for this topic. Whatever training your employer or the applicable law requires sets its own standard; 70% is shown on your results as a common reference line, not an official cutoff.

Sit one full paper and you get a readiness figure for every topic on the course, not just a percentage.
