A.School Bus (S) and Passenger (P) endorsements

B.School Bus (S) endorsement only

C.Passenger (P) endorsement only

D.Hazardous Materials (H) and Passenger (P) endorsements

Explanation: Texas DPS lists S for school bus operation and P for passenger vehicles. Federal school bus endorsement rules also require the applicant to qualify for the Passenger endorsement.

A.Operation of any tank vehicle

B.Operation of a school bus

C.Transporting hazardous materials

D.Towing double or triple trailers

A.It replaces the CDL skills test

B.It is only for taxis and limousines

C.A school bus transports passengers and federal S rules require P qualification

D.It authorizes hazardous materials in a bus

Explanation: School bus authority is tied to both school bus and passenger qualification. The P endorsement does not replace skills testing or hazmat rules.

A.The Tank Vehicle (N) endorsement

B.A motorcycle endorsement

C.Only a vision screening

B.Only a knowledge test

A.To confirm students and traffic are clear of the bus danger zones
