The Free CDL School Bus Endorsement Practice Tests developed by CDL Digest each contain 20 multiple choice questions to help you pass the actual CDL School Bus Endorsement Test on the first attempt. You must have a score of 80% (16 out of 20 questions) or better to pass. A School Bus Endorsement is required to operate a commercial motor vehicle (CMV) designed to transport pre-K through high school students to and from home and school and school-sponsored events (49 CFR 383.5). If the school bus is designed to transport sixteen (16) or more students, including the driver, a passenger endorsement will also be required (49 CFR 383.91(a)(3)).

This endorsement can be added to a commercial learner’s permit (CLP) or commercial driver’s license (CDL).

Each Free Practice Test covers knowledge of the five (5) areas of safe operation for a school bus as required by Federal Regulation (49 CFR 383.123(a)(2)) as follows:

49 CFR 383.123(a)(2)(i): Loading and Unloading Children, Operation of Stop Signal Devices, External Mirror Systems, Flashing Lights, and Other Warning and Passenger Safety Devices Required by School Buses

49 CFR 383.123(a)(2)(ii): Emergency Exits and Safety Procedures for Evacuating a School Bus in an Emergency

49 CFR 383.123(a)(2)(iii): Railroad-Highway Grade Crossing Safety Regulations

49 CFR 383.123(a)(2)(iv): Other Practices and Procedures for Safe Operation (Vehicle Inspections, Antilock Braking Systems (ABS), etc.)

The above listed CDL School Bus Endorsement information for testing purposes can also be found in AAMVA’s “2005 CDL Test System (July 2010 or newer Version) Model Commercial Driver Manual”, which is made available at no cost at all 50 State Driver Licensing Agencies.

Section 10 of the CDL Manual covers the following topics for Safely Operating a School Bus:

Danger Zones and Use of Mirrors

Loading and Unloading Procedures

Emergency Exits and Evacuation Procedures

Railroad-Highway Grade Crossings

Student Management

Antilock Braking Systems (ABS)

Special Safety Considerations

The source material used by CDL Digest to develop these practice test questions is very technical. It may be necessary for you to take the Practice Tests several times to make sure you have a thorough understanding of all the material before taking the actual CDL School Bus Endorsement Test at your State Driver Licensing Agency.
