Braking/Stopping distances - Online Test
Ask 1

The average reaction time is around 1.5 seconds, which means that you will cover about 40m at 100 km/h before you start responding to a hazard.

What’s the average reaction time?

  • About 0.5 seconds
  • About 1 second
  • About 1.5 seconds
  • About 3 seconds
Ask 2

The two-stage braking technique improves braking effectiveness and reduces the risk of skidding, especially on wet or gravel roads. Two-stage braking is done by first setting up the brakes with light pressure on the pedal and then gradually applying the necessary braking pressure.

Are there any advantages of two-stage braking?

  • No, two-state braking doesn't provide any particular advantage
  • Yes, two-state braking reduces the risk of skidding
Ask 3

In bad conditions, the stop

What's the approximate stopping distance when driving 100 km/h on a dry road?

  • About 10-20 metres
  • About 50-60 metres
  • About 90-100 metres
  • About 150-160 metres
Ask 4

The stopping distance is the total distance it takes for your vehicle to come to a complete stop from the moment you spot a hazard, i.e. the distance you travel while reacting and the distance you travel while braking.

Which statement is true regarding the stopping distance?

  • The stopping distance is the same as braking distance
  • The stopping distance isn't affected by defective brakes
  • The stopping distance is the total reaction distance + braking distance
  • None of the above
Ask 5

Speed makes a huge difference in your ability to stop in time and a significant difference to your chance of being involved in a crash. Doubling the speed will increase braking distance by 4 times and reaction distance by 2 times.

Doubling the speed will do which of the following?

  • Increase the braking distance by 2
  • Increase the braking distance by 3
  • Increase the braking distance by 4
Ask 6

Think of reaction distance as the distance your vehicle has travelled while you react. At 100 km/h, you travel 27.8 m/s, which means that you travel roughly 40m during the 1.5 seconds that it takes you to react. This example shows the importance of kee

You're travelling at 100 km/h. How long will your reaction distance be?

  • 20m
  • 30m
  • 40m
  • 50m
