California CDL School Bus Test case studies

California CDL School Bus Test · Put your knowledge to work in context.

The California school bus endorsement - shown as an "S" on a Commercial Driver's License - is what allows a driver to operate a school bus, school pupil activity bus, or youth bus carrying students. It is issued by the California DMV and is aimed at drivers who already hold or are working toward a Class B (or Class A or C) CDL and want to transport pupils. Before you can take the knowledge test you must meet the DMV's eligibility steps, including holding a commercial learner's permit and passing the required background check through the Department of Justice and FBI, plus the medical and first-aid requirements the state sets for school bus drivers. The endorsement knowledge test is computer-based at a DMV office and focuses on the safety duties unique to school buses: loading and unloading students, managing behavior on board, railroad crossings, emergency evacuation, fire safety, pre-trip inspection, hazardous conditions, hours of service and reporting, and California-specific rules. The California CDL School Bus Test case studies are 5 cases and about 2,721 words.
