Mining and agriculture are just two of the massive industries in Colorado that fuel their large trucking industry. As a landlocked state, Colorado has a heavy demand for commercial drivers. The Centennial State offers some of the most beautiful natural scenery, and as a trucker you’ll have the chance to view more of the state than almost anyone else! You’ll spend much of your travels on Route 25, running straight up and down the center of the state through Denver and Colorado Springs. But before you can reap the financial rewards of commercial driving, you first need to get your Colorado commercial driver’s license (CDL). That’s a license to drive commercial motor vehicles, and it’s earned through a series of knowledge and skills tests varying in difficulty. But don’t worry, you can start studying now with our free Colorado CDL practice tests. Get a head start and find out where you stand by taking a free practice test now.
