Oklahoma has a large network of public school systems that rely heavily on school buses to transport students across the state. Many students, especially in the smaller rural communities, rely on school buses to get to and from school. The Oklahoma Department of Education ensures that all school buses undergo regular maintenance and that their drivers are qualified to operate them. In Oklahoma, all school bus drivers must obtain a CDL with a School Bus (S) endorsement, which is mandatory for driving any type of school bus. For operating type B, C or D school buses, you will also need a Passenger Vehicles (P) endorsement, which allows you to drive vehicles designed to transport 16 or more occupants, including yourself.
These endorsements can be obtained after passing their respective knowledge tests and a skills test in a school bus. We’ll help you prepare for the written School Bus knowledge test in Oklahoma, but there are several more steps you need to take. Aspiring school bus drivers must pass a Department of Transportation (DOT) medical examination as well as a criminal background check. All CDL holders are subject to random drug and alcohol tests throughout their career, so it is recommended to stay away from such vices while you are responsible for the safety of your passengers.

While the manual explains this subject in detail, its content might not be enough for you to pass the knowledge test on your first attempt. As an aspiring school bus driver, you must fully master this subject and use all the available learning resources.
