About the Idaho School Bus Test
Topics Covered
- ✓Loading and unloading procedures — Idaho requires you to stop 10 feet before the first student at a bus stop, and you've got to check all mirrors before moving. One mistake here and a kid can get hurt.
- ✓Railroad crossing rules — Idaho has hundreds of active crossings. You must stop 15-50 feet from the nearest rail, open the door, and look both ways. No exceptions on school bus routes.
- ✓Winter driving and chain use — Idaho law allows the state patrol to require chains on school buses. Know when to put them on and how to drive with them on icy grades like White Bird Hill.

📘 Study Tips & State Info
The Idaho DMV manual for school buses is your best friend. But don't just read it — visualize the roads you'll drive. When the manual says 'stop at all railroad crossings,' picture the crossing on State Street in Boise where the trains come through at 40 mph. When it says 'check your mirrors before pulling away from a stop,' imagine a kid chasing a ball behind the bus on a dirt road near Moscow.
Idaho examiners love to ask about the sequence of the eight-light warning system. Memorize it: yellow flashers first, then red flashers, then the stop arm extends. They also hammer the proper distance from railroad tracks — 15 to 50 feet from the nearest rail. That's a specific range you need to know.
Practice the questions about emergency evacuation. Idaho requires drivers to know the procedure for a bus fire, a crash, and a rollover. The test will ask what you do first in each scenario. Hint: it's always secure the bus and call for help. Focus on those step-by-step sequences and you'll pass.
Idaho CDL tests are administered by the Idaho Transportation Department (ITD) at DMV offices across the state. You can take the School Bus knowledge test at any location that offers CDL testing. Major offices include Boise (Chinden Blvd.), Idaho Falls (B Street), Coeur d'Alene (N.W. Blvd.), and Twin Falls (Addison Ave.). Appointments are recommended — walk-ins are accepted but you might wait hours.
You'll need to bring your current Idaho driver's license, a valid Medical Examiner's Certificate (DOT physical), and proof of residency. The fee for the School Bus endorsement knowledge test is $15 in addition to the standard CDL application fee. If you fail, you can retake the test the same day — but only once per visit. After that, you wait at least one business day.
Idaho has a unique requirement: you must complete a school bus driver training course approved by the Idaho State Department of Education before you can take the skills test. The written knowledge test comes first, then the training, then the road test. Check with your local school district for approved training providers. Don't skip this step — the DMW won't let you test without it.
About the Idaho School Bus Test
Idaho's school bus routes aren't all suburban cul-de-sacs. You'll be driving two-lane highways beside the Snake River, picking up kids on gravel ranch roads near Salmon, and crossing railroad tracks that see more grain trains than passenger trains. The Idaho School Bus endorsement (S) tests you on the specific knowledge you need to keep those kids safe in a 40-foot bus.
The test covers loading and unloading procedures — the most critical part of the job. Idaho law requires you to stop at all railroad crossings unless you're exempted by a local ordinance. You'll need to know the exact order of activating the eight-way light system, checking mirrors, and scanning for students who might run across the road.
Winter driving is a big deal here. Idaho school districts don't cancel for a dusting of snow. You'll face packed snow on Highway 26 through the Teton Valley and black ice on I-84 near Burley. The test includes questions about tire chains, proper following distance, and how to handle a bus that starts to slide on an icy road.
You also need to know student management basics — how to handle an emergency evacuation, where to place the bus in a crash, and your legal responsibilities under Idaho Code. The DMV examiners in Boise, Idaho Falls, and Coeur d'Alene all emphasize the same thing: the safety of the kids comes first, every time.
