Test Questions
4.1

Vehicle InspectionSystems, doors and panels, interior, roof hatches, seatbelt

Before you drive, you have to be sure the bus is safe. Review the previous driver's inspection report first — you only sign off on it once every defect listed has actually been certified as fixed or confirmed not to need repair. Signing it is you certifying that work was done.

4.2

Loading & Trip StartBaggage, hazardous materials, the standee line, destination stops

Never let riders leave carry-on baggage in a doorway or aisle — nothing should be able to trip another rider. Secure baggage and freight so the driver can still move freely, riders can still get out through any window or door in an emergency, and nobody gets hurt if something shifts or falls.

Hazardous Materials — What's Allowed Most hazardous materials simply can't go on a bus. What is allowed: small-arms ammunition marked ORM-D, emergency hospital supplies, and drugs. Small amounts of certain other hazardous materials are allowed only when the shipper genuinely has no other way to send them. Watch for the nine diamond-shaped four-inch hazard labels — explosives, gases, flammable liquids, flammable solids, oxidizers, poisons, radioactive material, corrosives, and miscellaneous hazardous materials — and never transport anything hazardous unless you're sure it's permitted.
4.3

On the RoadSupervision, stops, common accidents, curves, railroad crossings, drawbridges

Railroad Crossings Stop between 15 and 50 feet before the tracks. Look and listen both directions for a train, opening your forward door if it helps you see or hear better. After a train passes, confirm no second train is coming on another track before crossing. Never shift gears on a manual transmission while crossing. You don't have to stop — just slow and check carefully — at streetcar crossings, where an officer or flagman is directing traffic, when the signal is green, or at crossings marked exempt or abandoned.
4.4

After-Trip Vehicle InspectionEnd-of-shift reporting

Inspect your bus at the end of every shift. If you drive for an interstate carrier, you must complete a written inspection report for that specific bus, listing anything that could affect safety or cause a breakdown — and if nothing's wrong, the report should say so.
