How to use this practice set
- Answer without looking anything up. Each question locks after your first choice, so your score is honest.
- Read every explanation, even on questions you get right. The reasoning is what sticks.
- Note the topic on any miss. The study plan below shows where that topic sits in the federal curriculum.
- Aim higher than 80%. That's the minimum on the real assessment, not the goal.
Practice set: 18 questions

Study plan: where each topic lives in the curriculum
FMCSA sets the minimum theory curriculum in 49 CFR Part 380. Class A (Appendix A) and Class B (Appendix B) share the same five sections. Class B has no separate coupling and uncoupling unit. Use this table to turn a missed question into a focused review.
| Curriculum section | Practice topics above | How to study it |
|---|---|---|
| Basic operation | Coupling | Walk through a pre-trip inspection out loud in order. For Class A, learn the coupling sequence and the tug test until you can recite them. |
| Safe operating procedures | Space management, stopping distance, distracted driving | Memorize the following-distance rule and the three parts of stopping distance. Then practice estimating them when you're a passenger. |
| Advanced operating practices | Skid control | Learn each skid type with its cause and its fix. Most skid answers start with "stop doing what caused it." |
| Vehicle systems and reporting malfunctions | None in this set | Learn what roadside inspectors check, and what you must report after a trip. |
| Non-driving activities | Hours of service, drugs and alcohol, medical, post-crash, whistleblower | Make flash cards for the numbers: 11, 14, 8 and 30, 10 hours off, 0.04, 24 months, and the 10/100/100-foot triangle placement. |
| Hazmat units | How to study them |
|---|---|
| Basic introductory and operational requirements | Learn what shipping papers must show and where you keep them while driving. |
| Reporting crashes and releases; emergency response; operating emergency equipment | Learn who you notify and in what order, and how to use the equipment on board. |
| Tunnels and railroad-highway grade crossings; routes and route planning | Memorize the 15-to-50-foot stopping rule at crossings, and why some routes and tunnels are restricted. |
| Loading and unloading; bulk packages; HM on passenger vehicles | Learn placarding (all four sides) and the basics of segregating incompatible materials. |
| Engine (fueling); tire check; Hazardous Materials Safety Permits | Know the fueling precautions, the tire checks you make, and which loads need a safety permit. |
How the real ELDT assessment is different
This page is for practice. Here's how your actual theory assessment works.
- It comes from your training provider, inside the course you enroll in, and it covers that course's full curriculum.
- You need at least 80% overall, the federal minimum for theory.
- It's what gets reported. When you pass, the provider submits your completion to FMCSA's Training Provider Registry, and your state checks it before your test. See the full enrollment-to-completion process.
- There's no minimum number of hours. You can move as fast as you genuinely learn the material.

Questions drivers ask
Are these the questions on the real ELDT assessment?
No. We wrote them for study practice. Your training provider gives the real theory assessment inside the course, and the questions aren't published.
Can I pass ELDT with a free practice test?
No. ELDT only counts when a provider on FMCSA's Training Provider Registry delivers the training, gives the assessment and reports your completion. Practice questions help you prepare. They don't replace the course.
What score do I need on the real assessment?
At least 80% overall, the federal minimum for ELDT theory.
Will these help with my CLP knowledge test?
Somewhat. Topics like space management, skids and hours of service overlap. For the CLP test itself, study your state's CDL manual, because that's what the state tests are built on.
