South Dakota CDL endorsement practice tests

Each test below contains 25 multiple-choice questions selected from a stable, South Dakota-keyed shuffle of our question bank — meaning every visit shows the same set, so you can track which questions you have mastered and which still need review.

How to get your CDL in South Dakota

Every applicant in South Dakota follows the same federally-defined sequence, with a few state-specific touches handled by the South Dakota Driver Licensing Program:

1. Confirm eligibility. You must be at least 18 for intrastate driving in South Dakota and 21 for interstate or HazMat. You must hold a regular driver license and have lived in South Dakota long enough to establish residency for the agency.
2. Pass the DOT medical exam. A federally certified medical examiner must complete your Medical Examiner's Certificate (DOT card). Most CDL applicants schedule this before applying.
3. Apply for your Commercial Learner's Permit (CLP). Visit a South Dakota Driver Licensing Program office in Pierre or anywhere in South Dakota with proof of identity, residency, Social Security, and the CDL application. The CLP fee in South Dakota is approximately $68.
4. Pass the General Knowledge test. 50 multiple-choice questions, 80% required to pass. You must pass General Knowledge before adding any endorsement tests.
5. Add the endorsement knowledge tests you need. If you'll be driving a tractor-trailer, take Combination Vehicles. If your vehicle has air brakes, take Air Brakes. Add Hazardous Materials, Tank Vehicles, Doubles/Triples, Passenger Transport, or School Bus as required by your work.
6. Complete entry-level driver training (ELDT). Federal regulations require new CDL applicants to complete ELDT theory and behind-the-wheel training from a registered training provider before the skills test.
7. Hold your CLP for 14 days. Federal rule. South Dakota requires you to keep the CLP at least 14 days before the skills test. Permits are valid for 180 days.
8. Pass the three-part skills test. Vehicle inspection, basic control skills, and on-road driving.
9. Pay your CDL license fee. Approximately $109 in South Dakota.

Tips for passing your South Dakota CDL test the first time

Most CDL test-takers fail on details that the FMCSA Manual covers thoroughly: stopping distances, air-brake inspection sequences, placard colors, and the special rules for railroad crossings, work zones, and adverse weather. Use the practice tests above to identify your weak spots, then read the corresponding chapters of your South Dakota Commercial Driver Handbook (available free from the South Dakota Driver Licensing Program).

• Master General Knowledge first. Every endorsement assumes you know the basics — speed management, hazard perception, communication, and the "no-zone."
• Drill the air-brake test sequence in order. The air-brake check is one of the most-failed parts of the skills test. Memorize the steps and practice them on your training vehicle.
• If you'll haul HazMat, study the placards. Placard colors, hazard classes, and the segregation table are the most-tested HazMat topics.
• Review at least 100 practice questions per endorsement. Repetition trains your eye for the way official questions are written.
• Read the explanations. Don't just memorize answers — understand the underlying rule. The official test paraphrases the same concepts in different ways.
