About the DC CDL School Bus Exam

The DC CDL School Bus Endorsement Test is the DC DMV knowledge test for drivers who operate a school bus with passengers. It draws on Section 10 of the DC CDL Manual: danger zones and mirrors, loading and unloading, emergency evacuation, railroad crossings, student management, ABS, and special safety situations. OpenExamPrep offers this free, independent practice bank for those topics and the DC licensing rules and District school bus law that apply to school bus drivers.

Exam sponsor: District of Columbia Department of Motor Vehicles (DC DMV). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

DC DMV requires school bus applicants to pass the Passenger and School Bus knowledge tests (Section 10 of the DC CDL Manual) in English at the Deanwood Road Test/CDL Center, plus a road skills test in a school bus that includes a student discharge demonstration. Applicants must hold the learner permit at least 30 calendar days and complete ELDT before the road test, and a learner permit with S may not carry students. This bank is independent English-language multiple-choice practice by OpenExamPrep, not an official DC DMV test copy or simulation, and it does not replace the skills test.

DC CDL School Bus: Suggested Study Strategy

1Read Section 10 of the DC CDL Manual (2005 CDL Testing System, July 2014 version), and review Section 4 for the Passenger test you must also pass.
2Learn the stop sequence in order: amber lights at least 200 feet out, right signal 100 to 300 feet out, stop 10 feet from students, Park or Neutral with the parking brake, then red lights.
3Memorize the evacuation numbers: a safe place at least 100 feet off the road toward oncoming traffic, and at least 300 feet upwind if hazardous materials spill.
4At crossings, stop 15 to 50 feet from the nearest rail, open the service door and window, and allow your bus length plus 15 feet beyond the tracks.
5Plan for DC rules: English-only testing, a 60-minute limit, a three-day retest wait, and a 30-day learner permit hold before the road test.

Frequently Asked Questions

How many questions are on the DC CDL School Bus test, and what score passes?

DC DMV does not publish the number of questions. Federal rule 49 CFR 383.135 requires at least 80% correct on every CDL knowledge test, so aim for that standard across Section 10 of the DC CDL Manual.

Which tests do I need to drive a school bus in DC?

DC DMV's guide lists the Passenger knowledge test, the School Bus knowledge test, and a road skills test in a school bus, on top of the General Knowledge test for your CDL class. If the bus has air brakes, you also need the Air Brakes test to avoid an air brake restriction.

How long do I have, and what language is the test in?

DC DMV lists a 60-minute limit for CDL endorsement tests, and exceeding it counts as a failure. All DC CDL knowledge tests are in English only.

What must other drivers do when my DC school bus stops?

Under DCMR 18-2209, drivers approaching from any direction must stop at least 15 feet from a school bus with a flashing warning light or extended stop arm and stay stopped until the lights stop and the arm retracts. Oncoming drivers on a street with a median strip divider are exempt, so still check traffic before signaling students.

What happens if I fail the School Bus test?

You must wait three calendar days and may retest on the fourth day. If you fail six times within 12 months, you cannot take a seventh test until 12 months after the first failure. Each attempt costs $10.

Can I drive students while I hold a learner permit?

No. Under 49 CFR 383.25, a learner permit holder with the S endorsement may not operate a school bus with passengers other than auditors and inspectors, test examiners, other trainees, and the accompanying CDL holder. DC DMV also requires a 30-calendar-day permit hold before the road test.

Is this an official DC DMV practice test?

No. This is independent practice by OpenExamPrep, written in English multiple-choice format from the DC CDL Manual, DC DMV pages, DCMR 18-2209, and 49 CFR Part 383. It is a study aid, not an official DC DMV test copy or simulation, and it does not replace the road skills test.
