Free Wyoming CDL Permit Practice Test: General Knowledge 2025

We think you’ll like our free Wyoming CDL permit practice test! This practice test will help you study for the official CDL General Knowledge test on commercial driving theory, which is a necessary step toward obtaining a Commercial Learner’s Permit (CLP). You should start reading the official Wyoming commercial driver’s license manual (Wyoming CDL Handbook 2025) if you haven’t already done so. Then take this practice test. It will help you absorb all that material and become more accustomed to being tested on it. The practice test is based on the official state CDL manual, just like the official knowledge test. It’s up to date as of September, 2025 and has 50 multiple-choice questions. The questions on this practice test will assess your understanding of such topics as basic vehicle maneuvers, cargo management, emergency preparedness, and pre-trip inspections. However, this practice test differs from the official knowledge test in the extra learning aids it provides you with, including a hint and an explanation of the correct answer for each question, and an automated assistant for even more help.

Once you’ve obtained a Commercial Learner’s Permit (CLP), you’ll be able to legally practice commercial driving under supervision. By practicing commercial driving, you’ll become sufficiently good at it to pass the official skills test, a necessary step for you to obtain a Commercial Driver’s License (CDL). The skills test will evaluate you on performing basic vehicle maneuvers, a pre-trip inspection, and a road test.

Once you obtain a CDL and all the endorsements you need, you can begin your career as a full commercial driver. The most important sectors of Wyoming’s economy are mineral and energy production (mainly coal, oil, and natural gas) and tourism. Agriculture, while not as important as in the past, is still significant. Both agriculture and mineral and energy production are, of course, heavily dependent on truck transportation. Wyoming is home to many famous tourist attractions like Grand Teton National Park and Yellowstone National Park, which has created a demand for bus drivers to transport tourists.

One of the most important routes for long-haul truckers is Interstate 80 – but in winter, it can be dangerous because of high winds, ice, and snowstorms, especially near Laramie and Cheyenne. Other important commercial routes include Interstate 25, Interstate 90, and U.S. Route 287. U.S. Route 287 is used by many trucks carrying cargo between Wyoming and Colorado, but it’s marked by steep grades and sharp curves. Use caution when driving on it in bad winter weather.
