Passenger Transport
Put passenger safety at the center of every operating decision.
Carrying people changes the stakes of every procedure. Study pre-trip responsibilities, loading and unloading, passenger management, and emergency handling with the endorsement's core logic in mind: the driver is responsible for people who cannot see the road and did not choose the route. Most questions reward the answer that protects passengers first.
The rules that matter
- Buses stop between 15 and 50 feet before every railroad crossing regardless of the signals, then cross without shifting gears.
- No rider may stand forward of the standee line, and every passenger should be seated before the bus moves.
- Complete a pre-trip that includes the passenger items — emergency exits, signaling devices, and securement — not just the mechanical checks.
- Do not refuel with passengers aboard unless it's unavoidable, and never fuel inside a closed building with riders on the bus.
- Announce stops and hazards, and keep the aisle and doorways clear of baggage that could block an exit.

Look for these sections: Passenger Transport.
This content comes from the federal FMCSA regulations (49 CFR), not a state handbook, so the rules are the same nationwide. Your state agency may add its own endorsement requirements on top.
Where these rules come from
We do not copy official handbooks — most states do not allow it. What we do instead: state the rule in our own words, then name the official document behind it. 100 questions in this module cite 10 official documents, none checked earlier than 2026-05-17. The 6 most-cited are below.

How does a loaded bus handle differently from an empty one?
- A. It stops in half the distance
- B. It corners more sharply
- C. It steers with far less effort
- D. It takes longer to stop and accelerate
Show answer
D. It takes longer to stop and accelerate — Passenger weight is real load, so following distance and merging gaps that work empty are too short with a full bus.

Why should a bus driver brake and accelerate smoothly?

- B. Standing riders can be thrown off balance
