How to apply for a Commercial Driver License (CDL)

When you apply for a CDL class or endorsement, there may be paperwork requirements, medical requirements and testing requirements to complete before they can be added to your license. This page gives you the guidelines to help you understand what these requirements are. If you have access to a smart phone or computer, you can use our interactive driver’s license guide to get a list of requirements specific to your situation (see section below). We encourage you to read through the information on this page for the steps you’ll need to take to add CDL classes and/or endorsements to your license.

How to get a customized list of the requirements you will need to get any class and/or endorsement

The interactive driver licensing guide is a helpful tool for those looking for information on commercial driving requirements. The guide will provide you with a checklist of requirements, and allow you to pre-fill any required application(s) before visiting a DMV Customer Service Center. Depending on your eligibility, you may also be able to use the guide to electronically submit your application(s) and schedule an appointment with the DMV for expedited service.
