KSA Driving Theory Practice

Clear View: Practice Questions

Seeing clearly is essential to safe driving, and this topic covers how to keep your windows clear using the vehicle's climate controls as described in the handbook. In the example controls, the left knob adjusts air flow direction, the middle knob fan speed and the right knob temperature. The air conditioner purifies the air and removes water vapour, which helps against misting. For a fogged windscreen, turn the climate switches clockwise to the far right; use the rear window heating button for a misted rear window, and recirculation in tunnels.

Question 1On the climate controls described in the handbook, what does the LEFT knob adjust?

  1. AThe temperature
  2. BThe fan speed
  3. CThe direction of the air flow (correct answer)
  4. DThe radio volume

Correct answer: C. Left knob: fan (air) direction. Middle: fan speed. Right: temperature.Source: Handbook p. 231

Question 2You are driving through a tunnel. Which climate setting is useful?

  1. ATurning the fan off completely
  2. BMaximum fresh air from outside
  3. CRear window heating
  4. DAir recirculation inside the vehicle (correct answer)

Correct answer: D. The recirculation button keeps air circulating inside the vehicle, for example when driving in tunnels.Source: Handbook p. 231

Question 3On the climate controls, what does the middle knob adjust?

  1. AThe air direction
  2. BThe fan speed (intensity) (correct answer)
  3. CThe air conditioner
  4. DThe temperature

Correct answer: B. The central switch adjusts the fan intensity; its button turns on rear window heating.Source: Handbook p. 231

Question 4Which control helps clear a misted or frosted REAR window?

  1. AThe air recirculation button
  2. BThe rear window heating button (correct answer)
  3. CThe hazard light switch
  4. DThe temperature knob turned to cold

Correct answer: B. The central button turns on the rear window heating.Source: Handbook p. 231

Question 5On the climate controls, what does the RIGHT knob adjust?

  1. AThe temperature (correct answer)
  2. BThe air direction
  3. CThe fan speed
  4. DThe rear window heating

Correct answer: A. The right knob adjusts the temperature.Source: Handbook p. 232

Question 6How does the air conditioner (A/C) help keep the windows clear?

  1. AIt heats the rear window
  2. BIt increases humidity
  3. CIt purifies the air and removes water vapour (correct answer)
  4. DIt recirculates air in tunnels only

Correct answer: C. The A/C purifies the air and extracts water vapour, which helps clear fog.Source: Handbook p. 232

Question 7The inside of your windscreen fogs up. What does the handbook advise?

  1. ATurn all the climate switches clockwise to the far right (correct answer)
  2. BTurn all the switches to the far left
  3. CSwitch the fan off
  4. DTurn on air recirculation and the lowest fan speed

Correct answer: A. To get rid of fog on the front window, turn all the switches clockwise to the far right.Source: Handbook p. 232
