Hazard Perception Test

Before you begin the hazard perception test, you'll be shown a short video clip about how it works.

You'll then be shown a series of video clips on a computer screen. The clips:

  • feature every day road scenes
  • contain at least one developing hazard - but one of the clips will feature two developing hazards
  • A developing hazard is something that may result in you having to take some action, such as changing speed or direction.

How the hazard perception test scoring works

The earlier you notice a developing hazard and make a response, the higher you will score. The most you can score for each developing hazard is five points.

To get a high score you need to:

  • respond to the developing hazard during the early part of its development
  • press the mouse button as soon as you see a hazard developing

You won’t be able to review your answers to the hazard perception test.

If you click continuously or in a pattern during a clip a message will appear at the end telling you that you've scored zero for that particular clip.

An example of when to respond

Think of a parked car on the side of the road. When you first see it, it isn’t doing anything - it’s just a parked car. If you respond at this point, you wouldn’t score any marks, but you wouldn’t lose any marks.

When you get closer to the car, you notice that its right-hand indicator starts to flash. This would make you think that the driver of the car is going to move away. The hazard is now developing and a response at this point would score marks. The indicator coming on is a sign that the car has changed from a potential hazard into a developing hazard.

When you get closer to the car, you’ll probably see it start to move away from the side of the road. Another response should be made at this point.
