What is the minimum age requirement to obtain a CDL with a P endorsement?

The minimum age requirement to obtain a Commercial Driver's License (CDL) with a Passenger (P) endorsement is indeed 21 years old for interstate travel, while some states do allow individuals as young as 18 to drive for intrastate travel. This distinction is crucial because the federal regulations for commercial driving set the age of 21 as a standard for operating commercial vehicles across state lines. However, individual states can have their own rules regarding driving within their borders, which leads to the possibility of an 18-year-old being eligible for an intrastate CDL with a P endorsement in those states.

This requirement exists to ensure that drivers have the necessary maturity, experience, and understanding of the complexities involved in safely transporting passengers. Transporting passengers can involve additional safety considerations compared to other types of commercial driving, making the age requirement an important aspect of driver qualifications.
