Free DE CDL School Bus Practice Test 2025
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 DE commercial driver's license manual
- Triple-checked for accuracy
- Updated for July 2025
To become a school bus driver in Delaware, you must be at least 18 with 1 year of driving experience and hold a Commercial Driver’s License (CDL) with a “P” endorsement. The licensing process begins with a criminal history background check, a physical exam, and a drug test, which are mandatory requirements for this career path. You will then attend and pass a DOE-approved school bus driver training course, covering classroom instruction and behind-the-wheel training. The school bus endorsement (S) is granted after passing a 20-question multiple-choice school bus knowledge test and a road skills exam in a school bus.
We’ll help you pass the written knowledge exam, but you must devote the time and effort to master commercial driving theory. Our Delaware CDL School Bus Endorsement Practice Test is available online, 24/7. All you need to access it is a compatible device with a stable internet connection. This practice test has 20 questions based on the official Delaware Commercial Driver License Manual (Delaware CDL Handbook 2025). For your convenience, we have omitted any timer from this practice test. Rushing will cause you to make avoidable mistakes, so you should take your time and finish each training session at your own pace. Read every question twice and only select an answer when you’re confident of your choice.
This practice test is up to date as of July 2025. You will always practice with the latest version, regardless of when you start studying. Personalize your testing experience with the test settings menu, which can be accessed by clicking on the three dots in the top-right corner of the page. From here, you can activate the answer popularity feature, which gives you insight into the performance of other students. Use this feature to identify questions where misconceptions are common, and pay attention to the detailed explanation provided. Note this feedback in a notebook or notebook app so you’ll remember it if a similar question appears on the official exam.
Your dream career is within reach, but you must become a professional commercial driver before you can get behind the wheel of a school bus. Our Delaware CDL School Bus Endorsement Practice Test can get you there faster by helping you master commercial driving theory efficiently.
