Sample Washington DC School Bus Test Questions

Question 1

After securing a school bus for an evacuation, what should the driver do if time permits?

  1. A Close every window before students leave
  2. B Collect belongings left by students
  3. C Back the bus to the previous stop
  4. D Tell dispatch the location, conditions, and assistance needed

Correct answer: D – Tell dispatch the location, conditions, and assistance needed

The District of Columbia CDL manual instructs the driver to determine the safest evacuation method and secure the bus. If time allows, the driver should then notify dispatch of the evacuation location, existing conditions, and the type of assistance needed. Searching for belongings or repositioning the bus could delay the evacuation and is not part of this procedure.

  1. A Passenger and combination vehicle endorsements
  2. B Passenger and school bus endorsements
  3. C Tank vehicle and hazardous materials endorsements
  4. D School bus and double/triple trailer endorsements

Correct answer: B – Passenger and school bus endorsements

Federal CDL rules require the appropriate passenger endorsement to operate a passenger vehicle and a school bus endorsement to operate a school bus. An applicant for the school bus endorsement must first qualify for the passenger vehicle endorsement.

  2. B To eliminate every blind spot around the bus
  3. C To observe danger zones for students, traffic, and other objects
  4. D To read warning signs without turning your head

Correct answer: C – To observe danger zones for students, traffic, and other objects

The District of Columbia CDL manual emphasizes that properly adjusted mirrors help the driver observe danger zones around the school bus. Drivers use the mirror system to look for students, traffic, and other objects that may not be directly visible. Each mirror should be checked before operating the bus to obtain the greatest available viewing area.

  1. A Safety red
  2. B Fluorescent yellow
  3. C Orange yellow
  4. D National school bus yellow

Correct answer: D – National school bus yellow

The standardized color is known as National School Bus Yellow, also historically described as National School Bus Glossy Yellow.

Question 5

Based only on passenger capacity, what is the largest vehicle capacity still below the CDL threshold of 16 people?

  1. A 6 people, including the driver
  2. B 9 people, including the driver
  3. C 15 people, including the driver
  4. D 22 people, including the driver

Correct answer: C – 15 people, including the driver

Under the federal CDL definition, a vehicle designed to transport 16 or more people, including the driver, is a commercial motor vehicle based on passenger capacity. A capacity of 15 is the largest capacity below that threshold. Other characteristics, such as vehicle weight or hazardous-material transportation, can independently make a vehicle subject to CDL requirements.

Question 6

What does the school bus “danger zone” include?

  1. A The first passenger row behind the driver
  2. B Only the area immediately behind the bus
  3. C Areas outside the bus where children are most at risk of being struck
  4. D Only the roadway used by passing vehicles

Correct answer: C – Areas outside the bus where children are most at risk of being struck

The District of Columbia CDL manual defines the danger zone as the area on all sides of the bus where children are most at risk of being struck by another vehicle or by the school bus itself. It includes areas in front, along both sides, and behind the bus. Drivers must use mirrors and direct observation to monitor these areas carefully.
