You’re planning to earn your Commercial Driver’s License in Wyoming — and there’s never been a better time. Wyoming’s economy runs on industries that demand skilled commercial drivers: coal mining in the Powder River Basin, oil and gas extraction across the basins, trona and soda ash mining near Green River, and a booming tourism sector funneling millions of visitors to Yellowstone and Grand Teton National Parks every year. With just over half a million residents spread across the 10th largest state by land area, Wyoming relies heavily on commercial drivers to move goods, fuel, and materials across vast distances.

But driving a commercial vehicle in Wyoming isn’t like driving in flat, temperate states. You’ll face some of the most extreme conditions in the country — hurricane-force winds across the High Plains, blizzards that shut down I-80 for days, black ice on mountain passes, and routes where you can drive 100 miles without seeing a fuel stop or cell signal. The Wyoming CDL exam, administered under federal FMCSA guidelines, is designed to ensure you’re ready for all of it.

This guide covers everything you need to prepare for the Wyoming CDL test: exact test format, state-specific requirements, what makes Wyoming driving unique, and free practice tests for every knowledge exam you’ll face.

Wyoming CDL Requirements: What You Need to Know

Wyoming follows the federal CDL standards established by the FMCSA under 49 CFR Part 383. The Wyoming Department of Transportation (WYDOT) and local DMV offices administer the CDL program statewide. Here’s exactly what Wyoming requires:

Age Requirements in Wyoming

License Type	Minimum Age	Restrictions
Intrastate (Wyoming 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

Wyoming CDL Fees

Fee Type	Amount	Details
Commercial Learner’s Permit (CLP)	$45	Valid for up to 180 days
CDL Issuance	$55	New CDL or renewal
Skills Test	~$100	Varies by testing location; verify with local DMV
Endorsement Fees	$5–$30 each	Varies by endorsement type; contact local DMV

Note: Fee amounts are based on available data and may change. Contact your local Wyoming DMV office in Cheyenne, Casper, Laramie, Gillette, Rock Springs, or Sheridan to confirm current rates before applying.

Wyoming ELDT Requirements

Since February 7, 2022, all new CDL applicants in Wyoming must complete Entry-Level Driver Training (ELDT) through an FMCSA-approved training provider. This is a federal requirement — no state can waive it. Wyoming 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 — this is a federal minimum that applies in Wyoming just as in every other state. Your CLP is typically valid for 180 days.

Wyoming CDL Test Format: What to Expect

The Wyoming CDL exam has two parts: knowledge tests (written) and a skills test (driving). The knowledge tests are computer-based, multiple-choice, and administered at Wyoming DMV offices or approved testing facilities.

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 Wyoming CDL knowledge tests follow FMCSA content standards based on the federal CDL Manual. The passing score is 80% on every test — no exceptions. Questions cover vehicle inspection, safe driving practices, cargo management, CDL regulations, and endorsement-specific content.

Wyoming Skills Test: Three Parts

The Wyoming CDL skills test is administered by approved testers at DMV offices or through authorized third-party testing facilities. 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 compartment, brakes, tires, lights, mirrors, steering, coupling systems
2. Basic Vehicle Control	Backing and maneuvering	Straight-line backing, offset backing, parallel parking, alley dock maneuvers
3. On-Road Driving	Real-world driving	Lane changes, turns, braking, gear usage, speed management, urban and rural road driving, traffic law compliance

Wyoming skills test retake policy: If you fail any section, you only retake the failed portion. The federal minimum waiting period is 1 business day for knowledge test retakes and 14 days for skills test retakes. Verify specific retake policies and fees with your local Wyoming DMV office, as state-specific details may apply.

What Makes Wyoming 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 Wyoming presents some of the most challenging and unique driving conditions in the nation. Here’s what sets driving in the Equality State apart:

Extreme Wind — The #1 Hazard for Wyoming Truckers

Wyoming is consistently ranked as one of the windiest states in the country. The combination of high elevation, open terrain, and prevailing westerly winds creates sustained winds of 30–50 mph with gusts exceeding 70 mph — especially along the I-80 corridor. The area around Elk Mountain, between Laramie and Rawlins, is notorious for semitruck rollovers caused by wind. WYDOT frequently issues high-wind warnings and even closes I-80 to lightweight and high-profile vehicles when gusts become dangerous. If you’re driving a CDL vehicle in Wyoming, understanding wind management — load distribution, speed reduction, and knowing when to park it — isn’t optional. It’s survival.

Wyoming-Specific Driving Conditions

• Rocky Mountain terrain: Wyoming sits at an average elevation of 6,700 feet — the second-highest mean elevation in the Lower 48. Mountain passes like Togwotee Pass (9,658 ft) and Powder River Pass (9,668 ft) demand steep-grade driving skills, engine braking knowledge, and gear management
• Brutal winters: Temperatures routinely plunge to -30°F with wind chills reaching -80°F. Blizzards can reduce visibility to zero in minutes, and black ice forms on bridges and shaded sections of road even on seemingly clear days
• Rapid temperature swings: It’s not uncommon for Wyoming to see 50°F or greater temperature changes in a single day — a 60°F afternoon can drop to 10°F by nightfall, creating instant ice on wet roads
• Energy industry dominance: The Powder River Basin produces over 40% of all US coal. The Green River area is the world’s largest source of trona (soda ash). Oil and gas operations span the state. HazMat and tanker endorsements are exceptionally valuable here, with unique oilfield and mining-site driving conditions
• Vast remote distances: Wyoming is the least populated state in the nation. Driving I-80 across southern Wyoming means 400+ miles with long stretches between fuel, food, and cell service. Route planning and emergency preparedness are essential skills
• Wildlife collisions: Wyoming has one of the highest rates of wildlife-vehicle collisions in the US. Elk, moose, mule deer, pronghorn, and even bison regularly cross highways — especially at dawn and dusk. Hitting a 1,200-pound elk at 65 mph in a loaded tractor-trailer is a catastrophic event
• Two-lane roads: The vast majority of Wyoming highways are two-lane roads. Overtaking safely, managing speed on narrow mountain roads, and dealing with oncoming traffic on US-14, US-16, and US-20 require skills that urban drivers rarely develop
• Open range and livestock: Cattle ranching is a major Wyoming industry. In open-range areas, livestock can appear on the roadway at any time. Cattle guards line rural routes, and hitting livestock is both dangerous and legally costly
• Continental Divide driving: I-80 crosses the Continental Divide, and routes through South Pass and Togwotee Pass take drivers over the spine of North America. Weather can differ dramatically on each side of the Divide
• Seasonal tourism surges: Yellowstone and Grand Teton National Parks draw over 4 million visitors annually. Summer means heavy RV traffic, tour buses, and rental vehicles on narrow mountain roads — many driven by people unfamiliar with mountain driving

While the CDL knowledge test itself won’t ask you Wyoming-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 memorizing. Wyoming doesn’t forgive mistakes — preparation is everything.

Wyoming CDL Frequently Asked Questions

How many questions are on the Wyoming CDL General Knowledge test?

The Wyoming 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, shifting procedures, and more. It’s the same format and difficulty level used in every other state under FMCSA standards.

How much does a Wyoming CDL cost?

The total cost includes a $45 CLP application fee and a $55 CDL issuance fee. You’ll also pay a skills testing fee of approximately $100, plus any endorsement fees ($5–$30 each). Additional costs include your DOT medical exam (typically $75–$150) and ELDT training, which varies widely depending on the school and program you choose.

What happens if I fail a Wyoming CDL knowledge test?

If you fail a knowledge test, you can retake it. The federal minimum waiting period is 1 business day between knowledge test attempts. Retake fees may apply — check with your local Wyoming DMV office for specifics. We strongly recommend using our practice tests until you consistently score above 80% before scheduling your official exam.

Can I get a Wyoming CDL at 18?

Yes. Wyoming allows you to get a CDL at 18 for intrastate driving only — meaning you can drive commercially within Wyoming but cannot cross state lines until you turn 21. The HazMat endorsement requires you to be at least 21, regardless of your license type. Given Wyoming’s energy industry, many 18-to-20-year-old drivers find work hauling coal, gravel, or equipment within the state.

Where do I take the Wyoming CDL skills test?

Wyoming CDL skills tests are administered at DMV offices and approved third-party testing facilities across the state. Major testing locations include Cheyenne, Casper, Laramie, Gillette, Rock Springs, Sheridan, and Jackson. You must provide your own vehicle for the test — it must match the class of license you’re applying for. Call ahead to schedule an appointment, as walk-in availability is limited.

Is the Wyoming 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. Questions about vehicle inspection, safe driving, cargo securement, and endorsements are standardized nationally. Your Wyoming CDL is valid in all 50 states, and a CDL earned in another state can be transferred to Wyoming (with possible additional testing or fees). What differs is the driving environment — Wyoming’s extreme wind, cold, altitude, and remote distances make real-world experience here especially demanding.

Do I need special training for Wyoming’s mountain passes?

While the CDL knowledge test covers mountain driving theory, nothing replaces real experience. Wyoming’s mountain passes — including Togwotee Pass, Powder River Pass, and the roads through the Bighorn and Wind River ranges — feature steep grades, sharp switchbacks, and rapidly changing weather. Your ELDT behind-the-wheel training should include grade driving if possible. Many Wyoming driving schools incorporate mountain driving into their programs specifically because of this need.

Are chains required in Wyoming?

Yes. During winter months, WYDOT can require tire chains on certain routes — particularly mountain passes and I-80 during storms. Commercial vehicles may be required to chain up or park until conditions improve. WYDOT posts active chain requirements and road closures on wyoroad.info, which every Wyoming CDL driver should bookmark.
