Sample Iowa Passenger Test Questions

Question 1

Which hazardous item is specifically permitted as an exception to the general restriction on explosives in a bus’s passenger space?

  1. A Division 2.3 poison gas
  2. B Properly prepared small-arms ammunition
  3. C Gasoline in passenger fuel cans
  4. D Labeled radioactive material

Correct answer: B – Properly prepared small-arms ammunition

Federal passenger-carrying vehicle regulations specifically except small-arms ammunition from the general prohibition on Class 1 explosive material in the passenger space. The ammunition must still comply with applicable hazardous-material packaging and transportation requirements. Poison gas, gasoline carried by passengers, and labeled radioactive materials are not covered by this exception.

Question 2

Which front-tire condition would prevent a bus from being placed in service?

  1. A A recapped, retreaded, or regrooved tire is installed
  2. B The tires are an all-season design
  3. C Both tires were installed during the same month
  4. D The tires have more tread than those on the rear axle

Correct answer: A – A recapped, retreaded, or regrooved tire is installed

A bus may not be operated with regrooved, recapped, or retreaded tires on its front wheels. This is an exact federal equipment restriction and should be checked before the bus is driven. Front tires must also meet the applicable condition and tread-depth requirements, including at least 4/32 inch in each major groove.

Question 3

On an urban transit coach equipped with a brake-door interlock, opening the rear door applies the brakes and holds the accelerator at idle.

  1. A True
  2. B False

Correct answer: A – True

The statement is true. The Iowa CDL manual explains that a brake and accelerator interlock applies the brakes and keeps the throttle at idle while the rear door is open. Closing the door releases the interlock. The driver must not use this safety feature as a replacement for setting the parking brake.

Question 4

At a bus stop, one passenger has an automobile battery and another has gasoline in a fuel can. What should the driver do?

  1. A Permit both items if they fit under a seat
  2. B Permit the battery but refuse the gasoline
  3. C Permit the gasoline but refuse the battery
  4. D Do not allow either item aboard as passenger carry-on baggage

Correct answer: D – Do not allow either item aboard as passenger carry-on baggage

The CDL manual instructs bus drivers not to allow riders to carry common hazardous materials such as automobile batteries or gasoline. Both can expose passengers to serious corrosive, fire, or vapor hazards if they leak, spill, or shift. The driver should refuse boarding while either passenger is carrying the described item.

Question 5

A transit bus must have its rear door open before the driver can set the parking brake.

  1. A True
  2. B False

Correct answer: B – False

Opening the rear door may activate a transit coach’s brake-door interlock, which applies the brakes and holds the throttle at idle. Closing the door releases that interlock. The interlock is a safety feature and must not be used as a substitute for setting the parking brake.

Question 6

Must a passenger bus make its routine railroad-crossing stop at a crossing marked “Exempt”?

  1. A Only when passengers are aboard
  2. B Only when transporting school-age children
  3. C No
  4. D Yes

Correct answer: C – No

In Iowa, no stop is required at a railroad crossing designated by an “Exempt” sign. A commercial driver who is not required to stop must slow down and check that the tracks are clear of an approaching train before proceeding. The driver must still obey traffic-control devices and ensure there is room to clear the crossing.
