What type of driver's license must school bus drivers possess?

School bus drivers must possess a commercial driver's license (CDL) because they are operating a vehicle designed to transport 16 or more passengers, which classifies it as a commercial vehicle. The requirements for obtaining a CDL include specific training, testing, and adherence to safety regulations that ensure drivers can handle larger vehicles and understand the responsibilities associated with transporting students safely.

A regular driver's license does not provide the necessary endorsement to operate a school bus, as it lacks the required knowledge and skills specific to larger, commercial vehicles. Similarly, temporary and private driver's licenses do not meet the legal requirements for operating a school bus. The CDL incorporates additional endorsements, which are necessary to demonstrate proficiency in handling a school bus, ensuring the safety of the students while they are being transported.
