Which type of CDL endorsement is required to drive school buses?

The correct endorsement required to drive school buses is the S endorsement. This specific endorsement allows the driver to operate a school bus, which is classified as a type of passenger vehicle designed to transport children to and from school or school-related activities.

In addition to passing the written and skills tests required for the commercial driver's license, obtaining the S endorsement typically involves additional training and testing that focuses on the special requirements and safety procedures necessary when transporting school children. This ensures that drivers are well-equipped to handle the unique environment of driving a school bus, including awareness of the safety protocols related to loading and unloading children.

While the P endorsement also pertains to passenger transport, it is broader and encompasses vehicles other than school buses, and does not include the specific regulations and training related to transporting school children safely. The A and B endorsements relate to different types of commercial driving, such as operating combination vehicles or heavy vehicles, and do not apply to school buses.
