Hazard Perception Test

Please note that the hazard perception test contains Flash so unfortunately will not work on iPhones or iPads.  If you are on one of those devices you can still use our Theory Test application.

Facts about the Hazard Perception Test

Fourteen video clips comprise the hazard perception or awareness test. Each will run approximately 60 seconds and will involve driving situations with other drivers. Each will present a video, shot from the driver’s point of view and will display a hazard or hazardous situation,an action, object or situation that will cause the driver to change speed or direction or stop. One of the video clips will present two hazards. The remaining 13 will show only one, but you will not be told which has multiple ones.

To correctly identify the hazard or hazards, you click the left or right mouse button. The faster you identify the hazard in the video, the more points you score on it, earning from zero to five points per clip. You cannot gain points by clicking everything you see on the screen. A blanket-video click series will earn you zero points.

You earn points by clicking the targeted hazard, but points are not detracted for clicking other legitimate hazards you may see.

You could easily see many potential hazards. The key is to identify which is or are actual hazards that cause action by the driver. By clicking on the actual hazard or hazards, you earn your points. Just be aware of the frequency of your clicks on one video. You lose nothing by noting potential hazards, so long as you don’t flood the scene.

Passing Rate

You must score at least 44 points out of a potential 75 to pass the hazard perception test.

Second Half Taken

Your hazard perception test is the second part of your driving theory test and is presented after a three-minute break that follows your multiple-choice test.

Once that three-minute break ends, you will see a short video tutorial on the hazards perception test. Once the tutorial is completed, the test videos will start. Be prepared.

What Is a Hazard?

A hazard can be defined by anything that cause a driver of a vehicle to change speed, direction or stop. It can be a moving object, a stationary object or a person. For testing purposes, you will not need to identify changing traffic lights, bends or curves in the road or an intersection. Be aware, though, that in real life, these are considered potential hazards. During the test, the hazards you will need to identify involve motion — a bus pulling from the curb, pedestrians or bike riders or cars, for instance.

Potential Hazards to Note


  • Blind bends
  • Brake lights on vehicles
  • Cyclists and motorbikes – especially young cyclists
  • Emergency vehicles
  • Indicator lights flashing
  • Lane changing – especially vehicles swerving to avoid hazards
  • Pedestrians – walkers, children playing, people with walking sticks
  • Poor road conditions – rain, fog, ice and snow
  • Poor visibility – especially bright sun low in sky, dusk, rain and spray
  • Road signs, they often relate to a hazard ahead

Residential Streets

  • Being forced out to the middle of the road by parking cars
  • Cars pulling into traffic right-of-way
  • Cars stopping to park
  • Children playing near the roadway
  • Especially those vehicles with restricted views
  • Oncoming traffic
  • Pedestrians crossing roads
  • Pedestrians stepping from behind cars
  • Traffic restrictions
  • Urban driving
  • Vehicles pulling out of side roads

Roads Near Schools

  • Children crossing without looking
  • Children cycling on pavements
  • Children playing near the road, especially games with balls
  • Crossing patrols and other forms of crossings
  • Ice cream vans

Country Roads

  • Animals, especially horses and riders, cows and sheep
  • Blind bends
  • Farm traffic and field gateways
  • Objects in the road especially manure, mud, hay and water
  • People walking against the flow of traffic
  • Single lane roads


  • Cars that have broken down
  • Cars changing lanes to overtake slower moving traffic
  • Cars entering the motorway
  • Cars leaving the motorway
  • Emergency vehicles
  • Road works
  • Stationary traffic
  • Traffic travelling much faster or slower than your vehicle

Hazard Test Preparation

One of the best ways to prepare for the hazard perception test is to travel in an auto mobile and practice spotting hazards as you travel. Some will remain as potential hazards while others will develop into actual hazards. Name each one and tell yourself what you would do to avoid the hazard.
