Are you studying to pass the official Idaho General Knowledge test so you can become eligible for a Commercial Learner’s Permit (CLP)? Worried that you may not pass without some additional help? We’re glad you chose us to help you, because we’re sure you won’t be disappointed. You’re not the only one who hasn’t mastered commercial driving theory by just reading the official Idaho Commercial Driver’s License Manual (Idaho CDL Handbook 2024). That’s why many other aspiring commercial drivers have decided to supplement their reading of the manual with other study tools.
This free Idaho CDL permit practice test is based on the official manual, just like the official General Knowledge test. And the practice test is up to date as of November, 2024. Practicing with it will help reinforce what you read in the manual. In addition, each of the 50 practice questions comes with a helpful hint and an explanation of the correct answer. The practice questions on this test will assess your knowledge of such topics as basic maneuvers, cargo management, emergency preparedness, and pre-trip inspections. Keep practicing your knowledge with as many of our practice tests as you can, as often as you can, until you feel confident that you’ve mastered the material and can ace the official General Knowledge test.
There’s one other major test you must take for a CLP: a medical examination. Once you pass those tests and meet some other requirements, you can obtain a CLP and start practicing commercial driving so you can pass the skills test for your Commercial Driver’s License (CDL). The skills test consists of three parts: basic vehicle maneuvers (such as backing), a pre-trip inspection of the vehicle, and a road test.
Once you get your CDL, you can start taking advantage of profitable opportunities in commercial driving. Idaho produces huge quantities of agricultural products, most famously potatoes, but also wheat, barley, and dairy products, all of which require truck drivers to transport. Folks who don’t live in Idaho may think of it as an agricultural state, but the state also has a large and growing industrial sector, especially in science and technology. High-tech businesses also require truck drivers to transport equipment and supplies to them as well as transport their finished products.
Another important economic sector is tourism. Idaho attracts visitors all year round to its national parks, ski resorts, and other tourist and recreational areas, creating a constant demand for bus drivers.
Major commercial routes include Interstates 84 and 90, U.S. Route 95, and State Highway 55.
