KSA Driving Theory Practice

Economic Driving: Practice Questions

Economic driving means looking ahead and driving smoothly, and this topic covers the habits the handbook recommends. Ease off the accelerator early when you see a red light instead of braking late, avoid unnecessary stops, keep a constant speed, and stay within 70-90 km/h where possible without exceeding 100 km/h. Switch off the engine if you will idle for more than 20 seconds. Check tyre pressure, use the air conditioner and rear window heater sensibly, close windows at higher speeds, and consider walking or car sharing. Dispose of old oil properly.

Question 1You see a red traffic light far ahead. What is the most economical way to approach it?

  1. ATake your foot off the gas early and let the car slow down without braking (correct answer)
  2. BKeep accelerating and brake hard at the line
  3. CShift to neutral and accelerate again
  4. DKeep your speed and brake at the last moment

Correct answer: A. A forward-looking style - easing off the gas so the car decelerates - uses no fuel and reduces brake wear.Source: Handbook p. 186

Question 2What is one of the key components of economic driving?

  1. AFrequent hard braking
  2. BStrong acceleration
  3. CA forward-looking driving style (correct answer)
  4. DDriving close to the car in front

Correct answer: C. One of the key components of economic driving is a forward-looking style.Source: Handbook p. 186

Question 3Why should you avoid stopping the car unnecessarily when driving economically?

  1. AThe engine switches off permanently
  2. BStopping is always illegal
  3. CThe brakes overheat when stopping
  4. DStarting again requires a lot of energy (correct answer)

Correct answer: D. Restarting from a stop requires a lot of energy, so avoid unnecessary stops.Source: Handbook p. 186

Question 4What does an automatic start/stop function do?

  1. AStops the car automatically at red lights
  2. BPrevents the car from exceeding the speed limit
  3. CSwitches the engine off when the car stops and restarts it when you release the brake (correct answer)
  4. DStarts the car with your phone

Correct answer: C. Start/stop turns the engine off when stopped and restarts it as soon as you take your foot off the brake.Source: Handbook p. 186

Question 5Your car has no start/stop function. When does switching off the engine save fuel?

  1. AEvery time you stop, even for 2 seconds
  2. BNever; restarting always uses more fuel
  3. CWhen you will be idling for more than 20 seconds (correct answer)
  4. DWhen idling for more than 5 minutes only

Correct answer: C. Without start/stop, switch off the engine if the idle time is longer than 20 seconds.Source: Handbook p. 186

Question 6Which speed range saves fuel, according to the handbook?

  1. A40-50 km/h
  2. B70-90 km/h (correct answer)
  3. C100-120 km/h
  4. D120-140 km/h

Correct answer: B. Speeds of 70-90 km/h save fuel; avoid driving above 100 km/h when trying to save fuel.Source: Handbook p. 187

Question 7When trying to save fuel, which speed should you avoid exceeding?

  1. A80 km/h
  2. B140 km/h
  3. C100 km/h (correct answer)
  4. D60 km/h

Correct answer: C. Avoid driving at any speed exceeding 100 km/h when trying to save fuel.Source: Handbook p. 187

Question 8Which habit helps save fuel?

  1. AKeeping a constant speed, e.g. with cruise control (correct answer)
  2. BIgnoring tire pressure
  3. CCarrying unnecessary heavy items
  4. DStrong acceleration from every stop

Correct answer: A. Avoid strong acceleration, keep a constant speed with cruise control, shed excess weight and check tire pressure regularly.Source: Handbook p. 187

Question 9What should you do regularly to save fuel?

  1. ACheck tire pressure (correct answer)
  2. BFill the trunk with spare items
  3. CUse the rear window heater
  4. DWarm up the engine for 10 minutes

Correct answer: A. Checking tire pressure regularly is one of the fuel-saving tips.Source: Handbook p. 187

Question 10How much fuel does the rear window heater use, and when should it be used?

  1. ANo fuel at all; any time
  2. BAbout 0.7 L per hour; only at night
  3. CAbout 0.7 L per 100 km; only when the rear window is foggy (correct answer)
  4. DAbout 7 L per 100 km; always

Correct answer: C. Rear window heating uses about 0.7 litres per 100 km and should only be used when the window is foggy.Source: Handbook p. 187

Question 11How should you use the air conditioner to save fuel?

  1. ADon't set it too low, use recirculation and keep the windows closed (correct answer)
  2. BSet it as cold as possible with windows open
  3. CUse it only with the rear heater on
  4. DTurn it on and off every minute

Correct answer: A. Never set the air conditioner too low, use the recirculation button and close the windows when it is on.Source: Handbook p. 187

Question 12Why should you close the windows when driving at 60 km/h or faster?

  1. ATo hear the engine better
  2. BOpen windows increase air resistance and fuel use (correct answer)
  3. COpen windows are illegal above 60 km/h
  4. DTo keep the seat belts working

Correct answer: B. Close the windows when driving at 60 km/h because of the air resistance.Source: Handbook p. 187

Question 13Which is a fuel-saving tip from the handbook?

  1. AUse the car for very short trips
  2. BDrive off straight away after starting the car (correct answer)
  3. CLet the engine idle for several minutes before driving
  4. DDrive mainly during rush hour

Question 14For very short distances, what does the handbook recommend?
