Do 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 2026), which you should read multiple times during your learning phase. You must score 80% or higher to pass, leaving little room for error.
