📘 Study Tips & State Info
Maryland MVA examiners love questions about the exact sequence of the pre-trip inspection for a school bus. Don’t just memorize the list — practice saying it out loud while you walk around a bus. They also hit hard on the proper use of the eight-light system and when to activate the alternating flashing amber lights versus the red stop lights.
Another thing: Maryland has specific rules about where you can load and unload students on state highways. The manual says you must load on the right side of the road unless a school official directs otherwise. Know that. And know the maximum speed for a school bus in Maryland — it’s 55 mph on interstates, but lower on undivided roads.
Use the MVA’s official School Bus supplement. It’s free online. Read it, then take our practice tests. Focus on questions about railroad crossings — Maryland requires a full stop even if there are no tracks visible (like at the light rail). That’s a common trick question.
Maryland MVA handles all CDL testing. You’ll take the School Bus written test after passing the General Knowledge exam. The test fee is $50 for the endorsement, plus the $30 for the knowledge test if you’re taking it separately. Appointments are required at most full-service MVA offices — walk-ins are rare and wait times can be over two hours at Glen Burnie or Bel Air.
You must bring your CLP, a valid Medical Examiner’s Certificate, and proof of Maryland residency. The MVA will also check your driving record — a suspended license in the last 5 years can disqualify you from the S endorsement. No exceptions.
After passing the written test, you’ll need to pass a skills test in a school bus. The MVA contracts with third-party testers at locations like the Baltimore County Public Schools bus depot. You’ll do a pre-trip, a basic control skills test, and a road test that includes a simulated student pickup.
About the Maryland School Bus Test
The Maryland School Bus endorsement (S) is required if you transport students in a yellow bus with a CDL. It’s not just about driving — it’s about managing kids, dealing with Maryland’s unpredictable weather, and navigating tight suburban streets in places like Montgomery County or Baltimore City.
You’ll take this test at any MVA full-service office. The written exam covers bus-specific inspection procedures, loading and unloading kids safely, and emergency evacuation drills. Maryland examiners pay close attention to your knowledge of crossing gates and alternating flashing lights — they’ve seen too many close calls on narrow roads like MD-140.
Expect questions about the pre-trip inspection of a school bus, including the stop arm, warning lights, and mirrors. You also need to know how to handle a bus when fog rolls in over the Chesapeake Bay Bridge. The state manual has a whole section on weather conditions — don’t skip it.
The test is 20 questions, same as the federal standard. You need 16 correct to pass. If you fail, you can retake it the next business day at most MVA locations, but you’ll pay the test fee again. So study right the first time.
