If you're planning to obtain your Commercial Driver's License (CDL) in Colorado, you've come to the right place. Colorado offers a variety of CDL classes designed to help you drive specific types of vehicles, from trucks and buses to hazmat and passenger vehicles. Let's delve into the key CDL classes offered in Colorado, their subcategories, and the types of vehicles you can drive with each.

Before we get started, it's essential to understand that to obtain a CDL in Colorado, you must be at least 18 years old, possess a valid Colorado driver's license, and pass a physical examination. You'll also need to complete a driving and knowledge test specific to the CDL class you're applying for. Now let's explore the CDL classes in Colorado.

CDL Class A
CDL Class A is the highest level of license offered in Colorado, enabling you to operate any combination of vehicles with a Gross Combined Weight Rating (GCWR) of 26,001 pounds or more, provided the Gross Vehicle Weight Rating (GVWR) of the vehicle(s) being towed exceeds 10,000 pounds.

CDL Class A licenses are further divided into subcategories, including:
Subdivision A

Issued to individuals who have obtained a valid CDL Class A license from another state and wish to transfer their endorsement to Colorado.
Though less common, it's important to note that another subcategory exists for individuals with disabilities who qualify for a modified vehicle. This will be discussed later in the article.
