HAZARD PERCEPTION - CAR

Hazard perception section

DSA hazard perception clips.

As with the multiple choice questions you will have the hazard perception section explained  before you comence this part and will be shown a breif video clip.

A serious of video clips will be shown to you 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.

Hazard perception scoring

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. It will tell you that you have scored zero for that particular clip.

An example of when to respond to a hazard

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.

The difference between a potential and developing hazard

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 will probably see it start to move away from the side of the road. You should make anothe response at this point.
