A Commercial Driver's License (CDL) is required in Wyoming to operate commercial motor vehicles over 26,000 lbs GVWR, buses carrying 16 or more passengers, or vehicles placarded for hazardous materials. Wyoming CDL fees start at $60 for a 4-year license. Three CDL classes are available: Class A for tractor-trailer combinations, Class B for single large vehicles, and Class C for passenger and HazMat vehicles. First-time applicants must complete Entry Level Driver Training (ELDT) through an FMCSA-registered provider before taking the skills test. All interstate CDL holders must maintain a valid DOT Medical Certificate. Test your knowledge with the Wyoming CDL knowledge test, then pass the skills test — pre-trip inspection, basic vehicle control, and road driving — to earn your license.
Any combination of vehicles with a GCWR of 26,001 lbs or more, provided the GVWR of the towed vehicle exceeds 10,000 lbs.
Any single vehicle with a GVWR of 26,001 lbs or more, or any such vehicle towing a vehicle with a GVWR not exceeding 10,000 lbs.
Any single vehicle or combination not covered by Class A or B, designed to transport 16 or more passengers including the driver, or required to be placarded for hazardous materials.
TSA security threat assessment and fingerprinting required. Valid 5 years. Critical for oil and gas field operations in the Powder River Basin, Wind River Basin, and Permian extension — Wyoming's dominant CDL employment sector.
Required for bulk liquid or gas transport. Essential for crude oil, produced water, and condensate haulers in Wyoming's oil and gas fields. Also relevant for water and chemical delivery to well sites.
Required for vehicles carrying 16 or more passengers including the driver. Wyoming's very low population means limited transit opportunities outside Cheyenne and Casper.
Requires P endorsement. Background check required. Wyoming's rural school districts cover enormous geographic areas.
Class A CDL required. Double and triple trailers are extremely common on Wyoming's I-80, I-25, and US-30 — Wyoming's wide-open highways and high speed limits favor multi-trailer configurations for efficiency.
Combination of H and N endorsements. TSA background check applies. The most critical endorsement combination for Wyoming's dominant oil, gas, and coal sector CDL employment.
Entry Level Driver Training (ELDT) is required by federal regulation (49 CFR Part 380, effective Feb 7, 2022) for first-time Class A or B CDL applicants, and for adding H, P, or S endorsements. Training must be completed through an FMCSA-registered provider listed in the Training Provider Registry (TPR) at tpr.fmcsa.dot.gov. ELDT providers may be limited in Wyoming's rural areas — plan for travel to Cheyenne, Casper, or a provider in a neighboring state.
Find a registered ELDT provider in Wyoming →Interstate CDL holders must hold a valid DOT Medical Examiner's Certificate (MEC) issued by an FMCSA-certified medical examiner, valid up to 24 months. Self-certify your operating category and submit the MEC copy to the Wyoming DOT Driver Services. Intrastate CDL holders may use Wyoming state physical standards.
Find an FMCSA-certified medical examiner →Apply at a WYDOT Driver Services office with proof of identity, Social Security Number, and Wyoming residency. Pass the required knowledge tests, complete ELDT through an FMCSA-registered provider, then schedule and pass the skills test. The CDL fee is $60. Wyoming is extremely rural — the nearest ELDT provider or skills test location may require significant travel. Visit dot.state.wy.us for current requirements and office locations.
Wyoming CDLs are valid for 4 years. Renewal costs $60. Your DOT Medical Examiner's Certificate must be renewed separately — typically every 24 months for most interstate drivers. The 4-year renewal cycle is shorter than many states.
Coal mining operations in Wyoming's Powder River Basin primarily use large off-highway haul trucks that do not require a CDL. However, road transport of coal, explosives (required for mining operations), and fuel supply to mine sites requires CDL with appropriate endorsements. HazMat (H) endorsement with TSA clearance is required for explosives and certain mining chemicals. Fuel tankers require N (Tank) and usually H endorsements — the X combination.
I-80 in Wyoming is one of the most weather-affected Interstate highways in the US. The stretch between Cheyenne and Laramie (including the Sherman Hill summit at 8,640 feet) experiences intense winds regularly — gusts exceeding 60 mph are common in winter and spring, and trucks are blown over multiple times per year. WYDOT issues wind advisories and closures for high-profile vehicles. I-80 also closes during blizzards. CDL operators should monitor WYDOT conditions at wyoroad.info before every trip across southern Wyoming.
Yes. Wyoming's truck speed limit is 75 mph on Interstate highways, one of the highest in the continental US. This reflects Wyoming's wide-open terrain and very low traffic volumes. However, this speed limit can only be safely utilized in good weather conditions — wind advisories, winter weather, and visibility restrictions frequently require significantly reduced speeds. Always comply with any advisory or mandatory speed reductions posted by WYDOT.
