Located in America’s Heartland, Iowa’s agricultural products of corn, soybeans, hogs, and cattle feed the nation. These massive industries have also built up a large infrastructure for their transport to the rest of the country, making commercial motor vehicle drivers very valuable to the Hawkeye State. Truckers in Iowa most often use Route 80, which stretches through Iowa City, Des Moines, and all the way to Omaha. But before you can get started in this rewarding career, you first need a CDL. A CDL is the license required to drive commercial motor vehicles, and it’s earned through a series of tests on your knowledge of safe vehicle operation. The tests aren’t easy, which is why we’ve created free practice tests for you to help you quickly determine where you stand. Each multiple-choice practice test is based off the same source as the real exam to ensure you have the most accurate and up to date information possible. Start your journey towards a career in commercial trucking with a free Iowa CDL practice test.
