You’re planning to get your Commercial Driver’s License in South Dakota — and you’re entering a state where trucking isn’t just a job, it’s a lifeline. With vast prairies, agricultural exports, and critical freight corridors running east-west on I-90 and north-south on I-29, South Dakota depends on commercial drivers to keep its economy moving. From hauling grain and cattle out of the eastern farmlands to transporting materials to the gold mines of the Black Hills, CDL holders are essential to this state.
South Dakota’s trucking industry serves a unique landscape — a state with fewer than 900,000 people spread across 77,000 square miles, where the nearest fuel stop might be 60 miles away and winter blizzards can shut down entire highways for days. The South Dakota Department of Public Safety (DPS) administers the CDL program under federal FMCSA guidelines, and the process is designed to ensure every driver handling an 80,000-pound rig through these conditions is fully prepared.
This guide gives you everything you need to prepare for the South Dakota CDL exam: exact test format, state-specific requirements, what makes driving in South Dakota different from anywhere else, and free practice tests covering every knowledge exam you’ll face.

South Dakota CDL Requirements: What You Need to Know
South Dakota follows the federal CDL standards established by the FMCSA under 49 CFR Part 383, with licensing administered by the South Dakota Department of Public Safety (DPS). Here’s exactly what South Dakota requires:
Age Requirements in South Dakota
| License Type | Minimum Age | Restrictions |
|---|---|---|
| Intrastate (South Dakota only) | 18 years | Cannot drive across state lines |
| Interstate (all states) | 21 years | No state-line restrictions |
| HazMat Endorsement | 21 years | Federal requirement — no exceptions |
South Dakota CDL Fees
| Fee Type | Amount | Details |
|---|---|---|
| CLP Application | $28 | Commercial Learner’s Permit |
| CDL (new or renewal) | $33 | Commercial Driver’s License |
| Skills Test | ~$100 | Varies by testing location |
| Endorsement Fees | $5–$30 each | Varies by endorsement type |
South Dakota’s CDL fees are among the most affordable in the nation — the CDL itself costs just $33, significantly lower than the national average. But remember that additional costs apply: your DOT medical exam (typically $75–$150), ELDT training ($3,000–$8,000 if attending a school), and endorsement fees can add up.
South Dakota ELDT Requirements
Since February 7, 2022, all new CDL applicants in South Dakota must complete Entry-Level Driver Training (ELDT) through an FMCSA-approved training provider. This is a federal requirement — no state can waive it. South Dakota DPS verifies ELDT completion electronically through the FMCSA Training Provider Registry (TPR).
ELDT is required for:
- Original Class A or Class B CDL
- Upgrading from Class B to Class A
- First-time School Bus (S), Passenger (P), or HazMat (H) endorsements
You must hold your Commercial Learner’s Permit (CLP) for at least 14 days before taking the skills test. Your CLP is valid for 180 days in South Dakota, giving you time to practice driving with a qualified CDL holder supervising.
South Dakota CDL Test Format: What to Expect
The South Dakota CDL exam has two parts: knowledge tests (written) and a skills test (driving). The knowledge tests are computer-based, multiple-choice, and administered at South Dakota DPS offices and authorized testing locations.
Knowledge Tests Overview
| Test | Questions | Pass Score | Required For |
|---|---|---|---|
| General Knowledge | 50 | 80% (40 correct) | All CDL classes |
| Air Brakes | 25 | 80% (20 correct) | Class A & B (if vehicle has air brakes) |
| Combination Vehicles | 20 | 80% (16 correct) | Class A |
| HazMat (H) | 30 | 80% (24 correct) | HazMat endorsement |
| Tanker (N) | 20 | 80% (16 correct) | Tanker endorsement |
| Passenger (P) | 20 | 80% (16 correct) | Passenger endorsement |
| School Bus (S) | 20 | 80% (16 correct) | School bus endorsement |
| Doubles/Triples (T) | 20 | 80% (16 correct) | Double/triple trailers |
All South Dakota CDL knowledge tests follow FMCSA content standards based on the federal CDL Manual and the South Dakota Commercial Driver’s Manual. The passing score is 80% on every test — no exceptions.
South Dakota Skills Test: Three Parts
The South Dakota CDL skills test is administered by DPS-approved examiners and authorized third-party testers. You must provide your own vehicle for the test, and it must be the same class of vehicle you’re applying for.
| Section | What It Tests | Details |
|---|---|---|
| 1. Pre-Trip Inspection | Vehicle safety knowledge | Verbally identify and explain critical components: engine, brakes, tires, lights, coupling systems |
| 2. Basic Vehicle Control | Backing and maneuvering | Straight-line backing, offset backing, parallel parking, alley dock |
| 3. On-Road Driving | Real-world driving | Lane changes, turns, braking, gear usage, speed management, traffic law compliance |
South Dakota skills test retake policy: If you fail any section, you only retake the failed section. The waiting period is 1 business day for knowledge test retakes and 14 days for skills test retakes. Contact your local DPS office for specific retake fees and scheduling.
What Makes South Dakota CDL Different from Other States?
The core CDL exam is federally standardized — the General Knowledge, Air Brakes, and endorsement tests cover the same material in every state. But South Dakota has specific characteristics that make driving here unlike anywhere else:
South Dakota-Specific Driving Conditions
- Brutal winter conditions: South Dakota winters are among the harshest in the lower 48 — temperatures regularly drop to -30°F with blizzards that create whiteout conditions, black ice, and snow drifts that can bury a truck. I-90 closes multiple times each winter due to blizzard conditions
- Persistent high winds: The open prairie offers no windbreak — sustained 30–40 mph winds are common, creating dangerous situations for high-profile vehicles, especially empty trailers and doubles
- Vast rural distances: South Dakota is the 17th largest state but has fewer than 900,000 people. Fuel stations, repair shops, and rest areas can be 60+ miles apart on rural highways — trip planning is critical
- Agricultural dominance: Agriculture is South Dakota’s #1 industry — corn, soybeans, wheat, cattle, and hogs all require massive trucking capacity, especially during harvest season (fall) and planting (spring)
- Black Hills and Badlands terrain: The southwestern corner features the Black Hills (rising to 7,242 feet at Black Elk Peak) and the rugged Badlands — steep grades, winding roads, and unique rock formations that demand careful driving
- Tourism season: Mount Rushmore, Badlands National Park, and Sturgis Motorcycle Rally bring massive seasonal traffic spikes — RV haulers, tour buses, and motorcycle transport all surge between June and August
- Energy industry: Wind farm construction and maintenance across the state requires specialized heavy haul transport, while gold mining in the Black Hills (Homestake Mine era) created a legacy of extractive industry trucking
- Indian Reservation routes: Large reservations including Pine Ridge and Rosebud span vast areas — commercial routes serving these communities require awareness of unique jurisdictional and road maintenance conditions
- Tornado season: April through June brings severe thunderstorms and tornadoes — drivers must monitor weather alerts and know emergency procedures, especially when hauling on open highways with no shelter nearby
While the CDL knowledge test itself won’t ask you South Dakota-specific questions beyond what’s in the standard handbook, understanding these conditions will make you a safer driver and help you contextualize the safety rules you’re learning. The section on extreme weather driving in your CDL manual isn’t just theory in South Dakota — it’s survival knowledge.

South Dakota CDL Frequently Asked Questions
How many questions are on the South Dakota CDL General Knowledge test?
The South Dakota CDL General Knowledge test has 50 multiple-choice questions. You need to answer at least 40 correctly (80%) to pass. The test covers vehicle inspection, safe driving practices, cargo management, CDL regulations, and more. It’s the same format and difficulty level used in every state under FMCSA standards.
How much does a South Dakota CDL cost?
The CDL itself costs just $33 — one of the lowest CDL fees in the country. Your Commercial Learner’s Permit (CLP) costs an additional $28. The skills test runs approximately $100 depending on the testing location. Factor in your DOT medical exam ($75–$150) and ELDT training ($3,000–$8,000 if attending a school), and your total out-of-pocket will depend heavily on your training path.
What happens if I fail a South Dakota CDL knowledge test?
If you fail a knowledge test, you can retake it after waiting 1 business day. For skills test failures, the waiting period extends to 14 days. There is no federal limit on retake attempts, but fees may apply for each attempt. We strongly recommend using our practice tests until you consistently score above 80% before scheduling your exam.
Can I get a South Dakota CDL at 18?
Yes. South Dakota allows you to get a CDL at 18 for intrastate driving only (within South Dakota). You cannot cross state lines until you turn 21. The HazMat endorsement requires you to be at least 21, regardless of your license type. Given South Dakota’s strong agricultural industry, many 18-year-old drivers start with intrastate CDLs hauling grain, livestock, or equipment.
Where do I take the South Dakota CDL skills test?
South Dakota CDL skills tests are administered at DPS offices and authorized third-party testing locations across the state. Contact your local DPS office or check with commercial driving schools for third-party tester availability. You must provide your own vehicle for the test — it must match the class of license you’re applying for. In rural areas, plan ahead as testing locations may be limited.
Is the South Dakota CDL test the same as other states?
The knowledge tests are based on the same FMCSA standards and cover the same material as in every other state. South Dakota uses the federal CDL manual content adapted in the South Dakota Commercial Driver’s Manual. Questions about vehicle inspection, safe driving, cargo securement, and endorsements are standardized nationally. Your South Dakota CDL is valid in all 50 states.
Do I need a HazMat endorsement in South Dakota?
It depends on what you plan to haul. South Dakota’s agricultural sector uses plenty of chemicals (fertilizers, pesticides) that require HazMat endorsements, and the energy sector transports flammable materials. A HazMat endorsement significantly expands your job opportunities in the state. It requires a 30-question knowledge test, TSA background check, and fingerprinting — and you must be at least 21 years old.
