Free DC CDL School Bus Practice Test 2025

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
  • Based on 2025 DC commercial driver's license manual
  • Triple-checked for accuracy
  • Updated for September 2025

To become a school bus driver in the District of Columbia, you must hold a valid Commercial Driver’s License (CDL) with a Passenger “P” endorsement. New drivers must also complete Entry-Level Driver Training (ELDT) from a provider listed in the Training Provider Registry (TPR). This is a federal requirement mandated by FMCSA on all US states and the District of Columbia. A valid DOT medical certificate is required to operate a school bus. You must also complete Human Trafficking Awareness Training before receiving a Commercial Learner’s Permit (CLP) or converting an out-of-state CDL.

Once the ELDT is complete, you must pass a 20-question knowledge exam on the safe operation of school buses. This exam is taken at a DMV location, and you must score 80% or higher to pass. All questions are taken from the official DC Commercial Driver License Manual (District of Columbia CDL Handbook), an essential resource that should not be missing from your toolkit. After that, you must pass a road skills test in a school bus. This includes a pre-trip inspection, basic vehicle control, on-road driving, and several procedures specific to school buses.

We’ll help you pass the official written knowledge exam by giving you access to our District of Columbia CDL School Bus Endorsement Practice Test. This intuitive tool has been designed to help you master commercial driving theory through active learning. With a user-friendly interface, even those who are unskilled with computers can easily control this practice test. Each question you get wrong will be automatically added to your personal Challenge Bank™. This section includes detailed explanations that can help you identify areas that need improvement and learn from your mistakes. Please keep in mind that questions in the Challenge Bank will remain there until you answer them correctly. Visit this section after each failed attempt and improve your knowledge through repetition.
