Which endorsement authorizes a CDL holder to drive vehicles carrying passengers?

The endorsement that authorizes a Commercial Driver's License (CDL) holder to drive vehicles carrying passengers is the "P" endorsement. This endorsement is specifically designed for drivers of buses and other passenger transport vehicles, allowing them to operate vehicles that can accommodate multiple passengers.

In the context of commercial driving, various endorsements are required for different types of vehicles and cargo. The "H" endorsement relates to transporting hazardous materials, while the "T" endorsement typically pertains to double and triple trailers. The "X" endorsement signifies a combination of hazardous materials and tank vehicle capabilities. Understanding these endorsements is crucial for CDL holders, as they need to possess the appropriate authorization for the type of vehicle they plan to operate. The "P" endorsement ensures that the driver has met the necessary requirements and training to safely transport passengers.
