Which type of vehicle requires a CDL to operate when equipped with air brakes?

A commercial vehicle that has a gross weight rating over 26,000 pounds requires a Commercial Driver's License (CDL) to operate, especially when it is equipped with air brakes. This is primarily because vehicles of this size and designation are often used for transporting goods or passengers for compensation, which mandates higher safety and operational standards. Air brakes are commonly found on large commercial vehicles like trucks and buses, as they provide more effective braking power under heavy loads compared to standard hydraulic brakes.

In North Carolina, as well as many other states, the requirement for a CDL is specifically tied to the vehicle's weight and its braking system, ensuring that drivers have the necessary training and skills to handle larger vehicles and their stopping distances safely. This regulation helps maintain road safety and ensures that drivers are adequately prepared to manage the complexities of operating larger, heavier vehicles.
