Commercial driving in the Equality State offers some substantial career benefits. Furthermore, becoming licensed to operate tractor-trailers and other combination vehicles is a great way to advance your earnings and job opportunities. To do so legally, you’ll need a Class A Commercial Driver’s License (CDL), and part of that process involves passing the Wyoming Combination Vehicles Knowledge Test. According to the Wyoming Commercial Driver License Manual, this license allows you to drive combination vehicles with a Gross Combination Weight Rating (GCWR) of 26,001 pounds or more, provided the towed vehicle exceeds 10,000 pounds Gross Vehicle Weight Rating (GVWR). A lot of material is tested on the official exam, but our experts have crafted a series of practice tests to help ensure you pass on your first attempt!
The official Wyoming Combination Vehicles Knowledge Test consists of 20 multiple-choice questions covering safe driving practices for combination vehicles, air-brake operation, coupling and uncoupling procedures, preventing skids and jackknives, and inspection procedures. You must correctly answer at least 16 questions (80%) to pass. If you don’t pass on your first try, Wyoming law requires a minimum one-business-day waiting period and a retest fee before trying again. Avoid these delays and added fees by preparing with our series of practice tests.

Before you can take the wheel, you’ll need to complete several other steps. You must complete Entry-Level Driver Training (ELDT) through an FMCSA-approved provider, pass the CDL General Knowledge Test (we have practice tests for that, too!), and earn your Commercial Learner’s Permit (CLP). Wyoming requires you to hold that permit for at least 14 days before scheduling and passing your on-the-road skills test (which must be completed in a combination vehicle).
Holding a Class A CDL opens doors to opportunities in Wyoming’s strongest industries like energy, agriculture, construction, manufacturing, and logistics. Interstates 80, 25, and 90 provide the primary infrastructure that makes driving in Wyoming such a lucrative endeavor.
Most combination vehicles use air brakes, so be sure to prepare for the Air Brakes Knowledge Test using our Wyoming Air Brake Practice Tests: https://driving-tests.org/wyoming/wy-cdl-air-brake-practice-test/. You can also expand your credentials with endorsements for Hazardous Materials (H), Tank Vehicles (N), and Doubles/Triples (T). We offer Endorsement Practice Tests as well: https://driving-tests.org/wyoming/wy-cdl-hazmat-practice-test/.
