View All PlansDo you know what sets school buses apart from other vehicles? They are built with special safety features that make them the safest mode of ground transportation for students in the United States. Their bright yellow color makes them visible in all weather conditions, while their elevated seating gives drivers a better view of the road ahead. Inside, school buses are equipped with closely spaced, high-backed seats that provide protection even without seat belts.
School bus drivers receive specialized training to handle student behavior, traffic situations, and emergency procedures. A strict licensing process ensures that only the most determined applicants get to operate these vehicles. To obtain a School Bus (S) endorsement on your Commercial Driver’s License (CDL), you must pass a 20-question knowledge exam and meet several other requirements. This test is based on the official Maine Commercial Driver License Manual (Maine CDL Handbook 2025), which you should read multiple times during your learning phase. You must score 80% or higher to pass, leaving little room for error.
Our Maine CDL School Bus Endorsement Practice Test is an intuitive tool designed to boost your learning potential. It includes several features you can use to customize your testing experience. The voice-over explanation, once activated, will use an artificial voice to read the questions and answer choices aloud. You can find this feature in the test settings menu, which can be accessed by clicking the three dots in the top-right corner of the page.
Studying commercial driving theory doesn’t have to be a chore. We simplify this process by providing a simple user interface. You can control the practice test even with minimal computer skills. You don’t need sophisticated software or a high-end computer to start. With unlimited attempts and nonstop access, you can easily incorporate this tool into your study routine.
Commercial driving is a skill that cannot be learned overnight. You must put in the time and effort to master this subject before you can get behind the wheel of a school bus. Our Maine CDL School Bus Endorsement Practice Test will speed up your progress, but you must stay consistent in your training.
