Is a CDL holder moving a school bus on a highway required to have the S endorsement also?
Guidance: No, a driver is only required to have an ‘S’ endorsement if they are transporting school children in the bus. But, a driver would be required to have a CDL ‘A’, ‘B’ or ‘C’ (depending on the size of the bus) with a ‘P’ endorsement, to be fully qualified, carrying a medical examiners certificate and be in a drug and alcohol testing program.
