What Is an ELDT Practice Test & Why It Matters
An ELDT practice test is a set of questions designed to mirror the knowledge checks you'll face during your Entry Level Driver Training theory course and your CDL written exam at the DMV. The federal ELDT mandate (49 CFR Part 380, effective February 7, 2022) requires specific curriculum topics — and our practice tests cover every one of them.
Here's why practicing before your real test matters:
- Identify knowledge gaps before the real exam, not during it
- Build confidence with repeated exposure to FMCSA-style question formats
- Reduce test anxiety — you've seen the types of questions before
- Save money — failing the DMV written test means retest fees and lost time
- Reinforce learning — active recall through practice questions is proven to be more effective than re-reading material
ELDT is a federal program — the curriculum is identical in all 50 states. Whether you're in Texas, California, Florida, or anywhere else, the same FMCSA-required topics apply. For a full breakdown of what ELDT covers and who needs it, see our ELDT Theory vs Behind-the-Wheel guide.

Sample FMCSA-Style ELDT Questions
Here are four real example questions similar to what you'll find in our practice tests and on the actual ELDT theory quizzes. Try them, then check your answers below.
Question 1 — Basic Operation (Class A)
When performing a pre-trip inspection on a combination vehicle, what should you check on the coupling system?
- A) Tire pressure on the steering axle only
- B) The fifth-wheel mounting bolts, jaws, and locking mechanism
- C) The color of the trailer
- D) The radio functionality
Answer: B — The fifth-wheel mounting bolts, jaws, and locking mechanism must be checked during pre-trip inspection. A failed coupling can cause the trailer to separate from the tractor — one of the most dangerous situations in commercial driving.
Question 2 — Hazmat Endorsement (H)
Which of the following is required on a vehicle transporting hazardous materials with placards?
- A) A fire extinguisher with a UL rating of 10 B:C or more
- B) A CB radio
- C) A GPS tracking device
- D) A passenger-side mirror only
Answer: A — Vehicles transporting placarded hazardous materials must carry a fire extinguisher with a UL rating of at least 10 B:C. This is a federal requirement under the hazardous materials regulations.
Question 3 — Safe Operating Procedures
What is the minimum following distance you should maintain when driving a commercial vehicle at speeds above 40 mph on dry pavement?
- A) 2 seconds
- B) 4 seconds
- C) 6 seconds
- D) 10 seconds
Answer: B — At speeds above 40 mph on dry pavement, you should maintain at least 4 seconds of following distance for a commercial vehicle. This accounts for the significantly longer stopping distance required by heavy vehicles compared to passenger cars. In adverse weather, this distance should increase to 6–10 seconds depending on conditions.
Question 4 — Hours of Service
Under FMCSA hours-of-service regulations, what is the maximum number of hours a property-carrying driver may drive after coming on duty?
- A) 8 hours
- B) 10 hours
- C) 11 hours
- D) 14 hours
Answer: C — Property-carrying drivers may drive a maximum of 11 hours after 10 consecutive hours off duty. The 14-hour driving window limit also applies — you may not drive beyond the 14th consecutive hour after coming on duty. These hours-of-service rules are a core component of the ELDT theory curriculum and appear frequently on both practice tests and real exams.
These are just four examples from our 25,000+ question bank. To take full-length practice tests with randomized questions across all topics, visit our free CDL practice test hub.
The 3 Endorsement Levels (H/P/S) & Which Theory You Need
If you already hold a CDL and want to add an endorsement, ELDT theory is required — but behind-the-wheel training is not. Endorsement-only applicants need just the theory component. Here's the breakdown:
Hazmat Endorsement (H)
Requires ELDT hazmat theory training covering hazardous materials regulations, placarding, shipping papers, emergency response, and security plans. Approximately 8 hours of curriculum across 14 units. After completing the free theory course, your record is auto-submitted to the TPR — then you take the hazmat knowledge test at the DMV and complete the TSA background check.
Passenger Endorsement (P)
Requires ELDT passenger theory training covering vehicle inspection, passenger management, emergency procedures, and safe loading/unloading. Approximately 6 hours of curriculum. Theory only — no behind-the-wheel required for the endorsement itself.
School Bus Endorsement (S)
Requires ELDT school bus theory training covering student safety, loading/unloading procedures, emergency evacuation, railroad crossings, and state-specific school bus regulations. Approximately 7 hours of curriculum. Theory only — no behind-the-wheel required for the endorsement.
For first-time CDL applicants, both theory and behind-the-wheel training are required. The theory portion — the part you can do online — is free at CDL Study Buddy. You can start with the free Class A ELDT theory course or the free Hazmat ELDT theory course — or browse the full ELDT training hub.

Frequently Asked Questions
Are the ELDT practice tests really free?
Yes. 100% free. No credit card required to take any practice test. No hidden subscription, no trial period, no limited number of questions before a paywall. The only paid feature on CDL Study Buddy is an optional ad-free subscription — it does not affect practice test access, theory course access, or TPR registration in any way.
Do the practice tests match the real FMCSA curriculum?
Yes. Our 25,000+ question bank is built around the FMCSA's ELDT curriculum framework under 49 CFR Part 380. Questions cover every required topic area: basic operation, safe operating procedures, advanced operating practices, vehicle systems, and non-driving activities. Endorsement-specific practice tests align with the hazmat, passenger, and school bus theory requirements. While no practice test can reproduce the exact questions on your real exam, our questions test the same knowledge in the same format.
Do I need ELDT for hazmat, passenger, or school bus endorsements?
Yes — if you're adding the endorsement for the first time, ELDT theory is required for Hazmat (H), Passenger (P), and School Bus (S) endorsements. However, behind-the-wheel training is not required for endorsement-only applicants — theory is the only ELDT component you need. If you held the endorsement before February 7, 2022, you do not need to retake ELDT. See our free Hazmat ELDT course or the full ELDT training hub for details.
What happens after I pass the ELDT theory course?
Your completion record is automatically submitted to the FMCSA Training Provider Registry. You can download your completion certificate from your dashboard. For first-time CDL applicants, your next step is Behind-the-Wheel training with a certified driving school before scheduling your CDL skills test at your state DMV. For endorsement-only applicants (H, P, S), theory is the only ELDT component required — you can head straight to the DMV to take your endorsement knowledge test.
