Home > ADI Part One > Hazard perception test
Before you start the hazard perception test, you’ll be shown a video about how it works.
You’ll then watch 14 video clips. The clips:
- feature everyday road scenes
- contain at least one ‘developing hazard’ - but one of the clips features 2 developing hazards
You get points for spotting the developing hazards as soon as they start to happen.
What a ‘developing hazard’ is
A developing hazard is something that would cause you to take action, like changing speed or direction. - As a driver would it make you hit the brakes or swerve?
Example A car is parked at the side of the road and isn’t doing anything. It wouldn’t cause you to take action, so it’s not a developing hazard.
When you get closer, the car’s right-hand indicator starts to flash and it starts to move away. You’d need to slow down, so it’s now a developing hazard.
How the scoring works
You can score up to 5 points for each developing hazard.
To get a high score, click the mouse as soon as you see the hazard starting to develop.
You don’t lose points if you click and get it wrong. However, you won’t score anything if you click continuously or in a pattern.
You only get one attempt at each clip. You can’t review or change your responses.
