To drive a school bus in New York State, you need a Commercial License with a School Bus “S” endorsement and a Passenger “P” endorsement. The “S” endorsement is required to drive specific types of school buses, and a school bus driver may not apply for the “S” endorsement unless they already have a “P” endorsement or are applying for both the “S” and the “P” endorsement at the same time. The CDL S endorsement is required if the school bus has a seating capacity of 16 or more adults (that includes the driver), or the school bus has a gross vehicle weight rating (GVWR) of more than 26,000 lbs. To apply for a Commercial License, you will need to pass a series of written and driven tests similar to that of your regular license, and you will need to pay a $10 charge for the permit. Once you have satisfied the requirements and turned in your application, you will be issued a temporary learners permit, which allows you to practice driving the type of commercial vehicle in which you are applying to drive, in this case, a school bus.
