OK CDL School Bus case studies
OK CDL School Bus · Put your knowledge to work in context.
The Oklahoma CDL School Bus (S) endorsement is the credential that lets a Commercial Driver License holder legally operate a school bus in Oklahoma. It is meant for drivers who already hold or are working toward a CDL and who will transport students for a school district or a contracted pupil-transportation company. The endorsement is added through separate knowledge testing, and it is not a substitute for the CDL general knowledge test; you must satisfy both. The Oklahoma knowledge test for this endorsement focuses on the situations that make school buses different from other commercial vehicles: the danger zones around a stopped bus, loading and unloading students, post-crash and evacuation duties, railroad-highway grade crossings, vehicle inspection and braking including antilock brake systems, student management and special situations, stop and light/sign procedures, and the handling characteristics of a bus. The OK CDL School Bus case studies are 5 cases and about 2,327 words.
