Practice for your Passenger CDL exam with questions based on the official Iowa CDL handbook
Which statement below about a bus’s interior is NOT true?
If a bus has a red emergency-exit light above an emergency door, that light must be in proper working order. You are required to switch it on only when visibility is poor enough that you have turned on your headlights (for example, at night or during bad weather).
Before beginning a trip, be sure to check:
As part of your pre-trip inspection, inspect the bus interior to verify that all handholds and railings are secure, all emergency exits are accessible and properly marked, and all signaling devices are functioning correctly. This includes the restroom emergency buzzer if the bus has a restroom.
When you change from high-beam headlights to low beams, what should you do?
After dimming your high beams to low beams, reduce your speed because low beams don’t illuminate as far ahead.
Which statement about looking ahead while driving is correct?
When driving, look ahead about 12–15 seconds. Stay aware of what is happening around your vehicle, both near and far. Continually move your focus between near and far areas and from left to right so you are always scanning.
At the end of each shift, you should:
Inspect your bust at the end of each shift. Riders sometimes damage safety-related parts such as handholds, seats, and windows. If you report this damage at the end of a shift, mechanics can make repairs before the bus goes out again.
In a pressurized cooling system, coolant level should be checked:
Before starting out, make sure the engine cooling system has enough water and antifreeze according to the engine manufacturer\'s directions. Visually check level of coolant and add more coolant if necessary.
Which statement below about hazardous materials is NOT true?
Most hazardous materials are not allowed on buses. Some limited types (for example, small-arms ammunition marked "ORM-D") may be permitted if the packages are correctly labeled. Do not permit any hazardous material on the bus until you have confirmed the rules allow it.
To reduce the risk of theft and vandalism on a charter bus, drivers should:
To help prevent theft or vandalism, charter bus drivers should not let passengers board the bus until it is time to depart.
Where on a bus is the standee line located?
Some buses are built to let passengers stand. They must indicate that standing is not allowed in front of the driver’s seat. One method is a standee line: a two-inch-wide line on the floor positioned just behind the driver’s seat.
When should you remind passengers to take their belongings with them?
Before the bus comes to a complete stop, remind passengers who are exiting to take their belongings. If the aisle is lower than the seats, also warn them about the step down.
The interlock system for the brake and accelerator on a transit coach may be used:
Urban mass transit coaches may have a brake and accelerator interlock system. The interlock applies the brakes and holds the throttle in idle position when the rear door is open. The interlock releases when you close the rear door. Do not use this safety feature in place of the parking brake.
You need to evacuate your bus in an emergency; passengers should be directed to a safe place no less than ____ feet from the bus.
Some tips to determine a safe place: A safe place will be at least 100 feet off the road in the direction of oncoming traffic.
__________ must be shut while the bus is moving.
Emergency exit windows and doors are required to be closed whenever the bus is being driven.
Which seats are required to have a seat belt installed?
Every bus must have a properly functioning seat belt at the driver’s seat. You should wear it any time the bus is moving. In a crash, the belt helps prevent serious injury or being thrown from the seat, which could cause you to lose control of the vehicle.
While operating the bus, is it allowed to have an emergency exit window open?
Do not drive the bus if any emergency exit door or window is open. During your interior pre-trip inspection, verify that all emergency exit doors and windows are firmly and securely closed.
When you’re driving, what does the term “hazard” mean?
A hazard is any road user or road condition that could potentially be dangerous. It’s something that might go wrong, but shouldn’t if you stay alert.
Your bus is disabled. The bus, with riders aboard, may be towed or pushed to a safe place only:
Do not tow or push a disabled bus with riders aboard the vehicle, unless getting off would be unsafe. Only tow or push the bus to the nearest safe spot to discharge passengers.
If your bus has an emergency exit door, it must:
Never drive with an open emergency exit door or window.
When are you required to complete a vehicle inspection report?
If you drive for an interstate carrier, you must complete a post-trip vehicle inspection report for every vehicle you operated during your shift, documenting any safety-related issues found and repairs you think are needed. This informs the next driver and the carrier about needed safety repairs. Federal rules require the report to be completed by the end of that day’s use of the vehicle. As of September 2020, if you find no defects and know of none, federal regulations no longer require you to submit a report. (49 CFR 396.11)
When approaching a drawbridge with no signal light or traffic control attendant, you must stop at least _______ from the bridge’s draw span.
If a drawbridge has no signal light or traffic control attendant, you are required to stop at least 50 feet before the draw span so you can confirm the bridge is closed and safe to cross.
The Passenger endorsement test is required in Iowa for drivers operating vehicles designed to carry 16 or more passengers. It covers passenger safety, loading procedures, emergency exits, and pre-trip inspection requirements.
The Passenger test is part of the CDL written exam administered by the Iowa Department of Motor Vehicles. You must pass this test along with the other required written tests to receive your Commercial Learner's Permit (CLP) in Iowa.
Our practice questions are built from the official Iowa CDL handbook and federal FMCSA regulations. Each question includes a detailed explanation to help you understand the material, not just memorize answers.
