Passenger CDL Endorsement Guide

What's tested

• Pre-trip inspection items unique to buses (emergency exits, signaling devices, seats)
• Passenger management and onboard conduct
• Standees and standee line
• Loading and unloading at stops, including disabled accessibility
• Railroad-highway grade crossings (mandatory stop for buses)
• Hazardous material rules specific to buses
• Post-trip inspection and end-of-route procedures
• Emergency situations (evacuation, fire, brake failure, accident)

Study notes

Buses have to stop at every railroad crossing.

A bus carrying passengers must stop between 15 and 50 feet from the nearest rail and listen for a train, even if there are no warning lights or the lights are dark. Open the door if the noise allows. The exception is a track marked "exempt" by the railroad authority. Failure to stop is one of the most-asked test questions on the P endorsement.

Standees are a numbered question.

On a transit bus, passengers may stand only behind the standee line on the floor (typically two feet behind the driver). On an intercity coach, no standees are allowed. Tour buses and motorcoaches generally do not allow standing while in motion; the test will ask you to know which configuration applies to which vehicle type.

Stops can be more dangerous than the route.

Most passenger injuries happen at stops, not at speed: people slipping on steps, being caught in closing doors, or stepping off into traffic. Always stop completely at the stop, set the parking brake, and watch the doors and the curb side mirror until everyone is clear.

You are responsible for what happens on the bus.

A bus driver can — and is expected to — refuse boarding to obviously intoxicated or disruptive passengers, and may put off any passenger who threatens the safety of others. You should never put a passenger off where it would be unsafe (e.g., on a freeway shoulder).

Post-trip child checks are mandatory.

On a school bus or any bus that may carry children, federal model rules require a post-trip inspection that includes walking the entire length of the bus before locking it up. This catches sleeping children before they're left in the bus on a hot afternoon. The same rule appears on the Passenger and (especially) the School Bus knowledge tests.

How to study for the Passenger exam

The single best preparation strategy for any CDL endorsement is to read the relevant chapter of your state's official CDL handbook three times: once to skim, once to highlight, and once to test yourself on the key terms in the chapter sidebars. The questions on the real exam are drawn directly from the handbook, often phrased almost identically to the bolded vocabulary terms. After you've read the chapter, work through every Passenger practice test on CDL Prep Hub for the state you live in.

Pace yourself. Most candidates who fail an endorsement exam fail because they tried to cram all eight written tests into a single weekend. Spread your study over two to three weeks, doing 30 minutes a night, and your retention will be dramatically better than a marathon Saturday session. The Passenger material in particular rewards spaced repetition because it includes a lot of numbers, regulations, and procedural steps that don't stick after a single pass.

Take the practice test in your state

Every state writes its own version of the Passenger exam, but they all conform to the same FMCSA standards. Pick your state below for a 25-question practice test sampled from the CDL Prep Hub question bank.
