📘 Study Tips & State Info
South Dakota examiners watch for one thing above all: safety first. They want to see that you understand why each rule exists, not just the rule itself. For example, when they ask about the 10-foot danger zone around the bus, don't just memorize the number — think about a kid dropping a backpack on a gravel road in January.
Focus on the pre-trip inspection section of the handbook. The SD DMV manual has a step-by-step checklist for school buses. Know it front to back. They'll ask about the stop arm test, the eight-light system, and the condition of the emergency exits. If you can't explain how to check the rear emergency door, you're not ready.
And here's a tip from 15 years of watching people test: don't skip the post-trip questions. A lot of drivers focus on loading and forget the final walk-through. In South Dakota, that walk-through can save a child's life in sub-zero temps. The examiners remember that.
South Dakota's DMV handles CDL testing at several locations. The main ones are in Pierre, Sioux Falls, and Rapid City. You'll need an appointment — walk-ins aren't guaranteed. Schedule online through the SD DPS website or call your local exam station. Fees for the School Bus endorsement are included in your CDL application fee, but if you're adding it later, it costs $10. Bring your Medical Examiner's Certificate and proof of residency.
South Dakota requires the School Bus endorsement (S) for any bus used to transport pre-primary, primary, or secondary school students. You also need a Passenger endorsement (P) if the bus seats more than 15 people. That's two separate written tests. You can take them back-to-back at the same appointment. The skills test for the school bus is a separate day — you'll drive a real bus with an examiner watching every move.
One thing that surprises out-of-state drivers: South Dakota doesn't have a reciprocity agreement for the S endorsement. Even if you hold it from another state, you'll retake the written test here. It's not hard, but don't assume your old endorsement transfers.
About the South Dakota School Bus Test
Driving a school bus in South Dakota isn't like driving one in a big city. You're handling kids on long, rural routes where the next town might be 30 miles away. Winter hits hard, and you can't just pull over and wait it out with a bus full of students. The South Dakota School Bus test makes sure you know how to handle those real situations.
The test covers federal standards but adds South Dakota-specific procedures. You'll see questions about loading and unloading on two-lane highways, crossing railroad tracks on back roads, and managing student behavior on long rides. The DMV expects you to know the pre-trip inspection cold — they watch for that during the skills test too.
You need 16 out of 20 to pass. That's 80%. Same as the other CDL tests. But don't rush — the questions aren't tricky, but they're specific. One wrong answer about when to activate alternating flashing lights can cost you.
If you're planning to drive for a school district in Sioux Falls, Rapid City, or any of the smaller towns, this endorsement is mandatory. You'll also need the Passenger endorsement (P) if you're driving a bus that carries more than 15 people. But the School Bus test is separate — don't skip it.
