Kentucky Passenger CDL Practice Test

This is a free 20-question practice test for the Passenger portion of the Kentucky Commercial Driver's License knowledge exam. Questions are pulled from a pool of 58 drawn from the AAMVA CDL Manual, which is the source document the Kentucky Department of Vehicle Regulation uses to write its actual exam.

How it works: Click an answer. The correct choice highlights in green, and you'll see a short explanation. Aim for 85% or better before you sit for the real test in Kentucky.

Question 1 of 20

Discharging passengers should be done:

Only at safe locations — paved curb, off the road, away from traffic
Anywhere
In the middle of an intersection
Only on highways

Correct. Stop at designated stops or safe pull-offs. Never discharge into a travel lane.

Question 2 of 20

Which of the following is part of the bus pre-trip inspection?

Passenger seat condition, emergency exits, signaling devices, kneeling mechanism, wheelchair lift if equipped
Only the engine
Only the brakes
Only the lights

Correct. Bus inspection includes all standard items plus passenger-area items: seats, emergency exits, signaling devices, kneeling/lift equipment, fire extinguisher.

Question 3 of 20

Most bus injuries during a trip happen because of:

Driver hitting another vehicle
Sudden stops, sharp turns, and quick lane changes throwing passengers
Engine failure
Fuel issues

Correct. Standing or unbelted passengers are vulnerable to abrupt motion. Smooth driving prevents most in-bus injuries.

Question 4 of 20

Bus brake systems require:

The same federal pre-trip air-system check as other commercial vehicles, with attention to bus-specific items (door interlocks, retarders if equipped)
No special check
Hydraulic checks only
Only the parking brake

Correct. Standard air-system check applies. Bus-specific: door safety interlock (door open = vehicle can't move), retarder/exhaust brake operation if equipped.

Question 5 of 20

You may NOT carry which of the following on a passenger bus?

Small-arms ammunition, hospital supplies in emergency
Class 2.3 (poison gas) or Class 7 (radioactive) above small quantities, tear gas, explosives other than small arms ammunition
Driver's personal luggage
Mail

Correct. Buses cannot carry Class 2.3 poison gases, most Class 7 radioactive materials, tear gas, or most Class 1 explosives. Small-arms ammunition and certain emergency shipments may be allowed.

Question 6 of 20

After every trip, the bus driver should:

Walk through the bus to check for sleeping passengers, lost items, damage
Lock the doors and leave
Only check the driver area
Skip the inspection

Correct. Always do a post-trip walkthrough — check every seat for sleeping passengers, lost items, and damage. Many news-worthy incidents involve passengers left aboard.

Question 7 of 20

A bus that has been in an accident:

Should be inspected before continuing in service
Can continue immediately
Is fine if no passengers complain
Does not require inspection

Correct. Post-accident inspection is required by carrier policy and federal rules. Damage to brakes, suspension, or structure may not be visible without inspection.

Question 8 of 20

When unloading passengers, you should:

Open the door only after stopping at the curb
Open while moving
Keep doors locked
Open only on driver request

Correct. Door interlocks usually require the parking brake set. Open after a complete stop at the curb.

Question 9 of 20

Buses must stop at every railroad crossing:

Yes, with limited exceptions (industrial switching tracks in city traffic, abandoned tracks, streetcar tracks)
No, never
Only at night
Only if a train is in sight

Correct. Buses, school buses, and placarded hazmat vehicles must stop at every railroad crossing 15 to 50 feet from the nearest rail, with narrow exceptions.

Question 10 of 20

When approaching a drawbridge, a bus must:

Stop at least 50 feet before the draw — unless there is a traffic light or attendant — and proceed only when you can do so safely
Cross at full speed
Honk the horn
Reverse

Correct. Stop at least 50 feet before any drawbridge. The exception is if there is a traffic-signal light or an attendant directing traffic, or the bridge has been closed and locked.

Question 11 of 20

A bus driver should:

Refuse boarding to obviously intoxicated passengers if they pose a danger
Carry any passenger
Carry only adults
Only carry seated passengers

Correct. Carriers may refuse boarding for safety reasons (intoxication, weapons, threatening behavior). Document and report such refusals.

Question 12 of 20

Stops requiring extra caution:

School zones, construction zones, intersections, slick roads
None of the above
Empty highways
Long straightaways

Correct. Anywhere with pedestrians, reduced visibility, or reduced control demands extra attention.

Question 13 of 20

When you are about to leave a stop with passengers aboard, you should:

Confirm doors are closed, mirror-check for late-boarding passengers and pedestrians, then proceed slowly
Move quickly
Use only the trailer brake
Skip the mirror check

Correct. Doors closed, mirrors check, slow gentle start. Late-boarders and pedestrians are common at busy stops.

Question 14 of 20

A passenger vehicle drove with people standing forward of the standee line. This is:

Acceptable
Prohibited — standees may not be forward of the line while the vehicle is in motion
Required
Encouraged

Correct. Standees forward of the line are at risk in emergency stops or sudden braking. Enforce the line.

Question 15 of 20

A bus driver who picks up a passenger between scheduled stops:

Is permitted in all cases
Must follow the carrier's policy and applicable regulations — many companies prohibit unscheduled pickups
Should always accept
Should always refuse

Correct. Carrier policy and regulations govern unscheduled stops. Most companies prohibit them for safety and liability reasons.

Question 16 of 20

You discover an emergency exit that does not function. You should:

Carry passengers anyway
Place the bus out of service until the exit is repaired
Tape it shut
Ignore it

Correct. A non-functional emergency exit puts passengers at risk. The bus is out of service until repaired.

Question 17 of 20

Maximum passenger capacity is determined by:

Vehicle manufacturer's rating and seating configuration
The driver's preference
The weather
The route

Correct. Manufacturer rating + seating config = maximum allowed passengers. Standees (where allowed) are capped by the standee-line capacity.

Question 18 of 20

Speed control on a long downgrade in a bus is critical because:

Brake fade can occur, and braking distance grows quickly with passenger load
Speed is irrelevant
Buses cannot go downhill
Speed is the same as a car

Correct. Heavy passenger load + long downgrade = brake fade risk. Select a lower gear before starting down and use intermittent firm braking.

Question 19 of 20

When approaching a stop where passengers will board, you should:

Slow gradually, signal, stop at the curb, set the parking brake, open the door
Stop suddenly
Drive past
Honk the horn

Correct. Plan the stop, signal, decelerate smoothly, stop at the curb, set the parking brake before opening the door — interlock should prevent door opening unless brake is set.

Question 20 of 20

After accepting passengers, the driver should:

Verify all are seated or behind the standee line, doors closed, parking brake released, then proceed
Move immediately
Wait until all are standing
Use only the trailer brake

Correct. Verify safety: all seated or behind line, doors closed, brake released, then proceed.

About the Kentucky Passenger exam

Most states administer 20 Passenger questions and require 80% to pass. The exam covers passenger safety, vehicle inspection, loading and unloading, prohibited cargo, emergency exits, and conduct expected of a passenger-vehicle operator. A separate skills test in a representative passenger vehicle is also required.

The Kentucky Department of Vehicle Regulation follows the federal CDL standards established by FMCSA. To earn the Passenger credential, you must answer at least 80% of the questions correctly. Many candidates score lower the first time because the test pulls from a large pool — refreshing this page will give you a different mix of questions, drawn from the same authoritative source.
