Sample Connecticut School Bus Test Questions

Question 1

The ABS malfunction lamp stays on while your school bus is moving. What should you do?

  1. A Stop using the regular brakes
  2. B Continue using the regular brakes and have the ABS serviced soon
  3. C Increase speed until the lamp turns off
  4. D Immediately evacuate every student

Correct answer: B – Continue using the regular brakes and have the ABS serviced soon

A malfunction lamp that remains on may indicate that ABS control has been lost at one or more wheels. The bus still has regular braking capability, so continue using the brakes normally and arrange to have the ABS serviced soon. The malfunction does not permit faster driving or less careful operation.

Question 2

Which condition should be considered when deciding whether a school bus evacuation is necessary?

  1. A An odor of raw or leaking fuel
  2. B Students speaking loudly
  3. C A missed passenger stop
  4. D A minor delay in the route

Correct answer: A – An odor of raw or leaking fuel

An odor of raw or leaking fuel is one of the conditions to evaluate when deciding whether evacuation is in the students' best interest. The driver should also assess fire danger, collision risk, hazardous spills, and dangers outside the bus. The decision must be timely and based on the specific hazard.

Question 3

When a vehicle defect is found, what information belongs on the Driver Vehicle Inspection Report?

  1. A The vehicle's future maintenance schedule
  2. B Defects that could affect safe operation or cause mechanical breakdown
  3. C The driver's hours-of-service totals
  4. D The amount of fuel used during the trip

Correct answer: B – Defects that could affect safe operation or cause mechanical breakdown

Federal rules require the report to list any discovered or reported defect or deficiency that would affect safe vehicle operation or result in mechanical breakdown. The driver must sign a required report. Before the vehicle is operated again, the carrier must repair a listed safety-related defect or certify that repair is unnecessary.

Question 4

Which situation requires a school bus evacuation?

  1. A The ABS malfunction lamp comes on
  2. B The bus stalls on a railroad-highway crossing, although no train is visible
  3. C The bus has a flat tire in a safe parking area
  4. D The bus is running behind schedule

Correct answer: B – The bus stalls on a railroad-highway crossing, although no train is visible

Connecticut's CDL manual lists a bus stalled on or adjacent to a railroad-highway crossing as a mandatory evacuation. The driver should not wait for a train to become visible before evacuating. An ABS malfunction is handled by using the regular brakes and arranging prompt service; it is not listed as a mandatory evacuation condition.

Question 5

After choosing the appropriate type of school bus evacuation, what should the driver do next?

  1. A Secure the bus
  2. B Collect students' personal belongings
  3. C Open every window
  4. D Move the bus to another location

Correct answer: A – Secure the bus

After determining the best type of evacuation, secure the bus. Place the transmission in Park, or Neutral if there is no Park position; set the parking brake; shut off the engine; remove the ignition key; and activate the hazard-warning lights. If time permits, the driver then notifies dispatch of the location, conditions, and assistance needed.

Question 6

What is required before a school bus driver changes the location of an official bus stop?

  1. A Verbal permission from the students
  2. B Approval from the other bus drivers
  3. C Written approval from the appropriate school district official
  4. D Notice to parents after the change is made

Correct answer: C – Written approval from the appropriate school district official

The Connecticut CDL manual explains that each school district establishes official routes and school bus stops. A driver should not change a stop's location without written approval from the appropriate school district official. Notice to parents or students does not replace the required approval.
