MO CDL School Bus case studies

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

The Missouri School Bus (S) endorsement is a commercial driver license endorsement that allows a qualified driver to operate a school bus. It is intended for applicants who already need, or are adding, a Missouri CDL and who will carry students. Missouri applies additional evaluation criteria to school bus endorsement applicants under §302.272 RSMo and 12 CSR 10-24.160, so the S endorsement is more than a standard knowledge-test add-on. The knowledge test is multiple choice and covers eight areas: danger zones and mirror use; loading and unloading; emergency exit and evacuation; railroad-highway crossings; student management; antilock braking systems; special safety considerations; and vehicle inspection and post-trip inspection. The MO CDL School Bus case studies are 5 cases and about 2,649 words.
