A Commercial Driver’s License (CDL) is a specialized permit mandated in the US for operating commercial vehicles like trucks, buses, and those transporting hazardous materials. Class A, B, and C are the main categories, with Class A covering the broadest range, including tractor-trailers, Class B for single vehicles over 26,000 pounds, and Class C for transporting 16+ passengers or hazardous materials.
To obtain a CDL, applicants undergo specific training, pass written tests tailored to their vehicle type, and demonstrate driving skills through practical exams. Regular medical checks and license renewals ensure drivers maintain the fitness necessary for safe commercial driving.
The CDL program is pivotal in regulating commercial driving, guaranteeing drivers possess the skills and qualifications needed to operate large vehicles securely, thus enhancing road safety and minimizing risks associated with commercial transportation.

Class b CDL Commercial Driver’s License
