Hazard Perception Theory Test

Hazard Perception Theory Module

When completing your LGV theory test, one of the sections the test includes is the hazard perception test. Also known as test 1b, this normally comes after the multiple-choice test.

Hazard perception test relates to “developing hazards.” This means anything which will cause you as a LGV driver to act. Such as changing speed, manoeuvring away or stop.

How To- Hazard Spotting

A hazard can range from and do not stop at

  • Another Driver or Road User
  • Pedestrians
  • Cyclists
  • Emergency Vehicles
  • Animals

Unlike a standard category b car theory test, the LGV hazard perception test will differ. As the training you are completing is for a larger, longer vehicle, you will be expected to understand different precautions and hazards.

For example, an LGV turning point is different from a standard car. An LGV reaction time is potentially slower. An LGV also takes up more room. These factors must be considered when you are taking the hazard perception test.

An LGV driver will have to complete different types of practical driver training, so the theory must account for this too.

As of 2023, the hazard perception HGV test consists of 19 videos. 18 of these videos will have one developing hazard within the content. 1 of the 19 videos will have two developing hazards within the video.

When watching these 19 video clips, you will have to click with your mouse when you predict that you see a developing hazard. The sooner you “react” to the developing hazard, the better you will score.

For example, if you click as soon as the developing hazard in question appears (this could be a cyclist coming out of a junction, which could alter your driving speed) you may score the maximum of five points. The longer you take to click the mouse over the course of the hazard developing, the fewer points you will score. If you click too late, or not at all, you will score zero for that clip.

However, if you “spam click” the video, you could lose out on the marks. You should only click when you believe to see a developing hazard.

You can achieve up to five marks per hazard. Out of the 19 video clips, this equates to a total of 100 achievable marks.

Pass Mark for Hazard Perception Test

To pass the hazard perception successfully, you must achieve at least 67 marks out of 100.

You must pass both the multiple-choice and hazard perception tests to fully pass the theory examination.
