The real UK hazard perception test uses video clips, but this practice page uses text-based road scenarios to help you understand how hazards develop in real driving situations.In Hazard Perception Test Practice 4, the scenarios are slightly more challenging. You may need to think about more than one possible risk at the same time, such as pedestrians near parked cars, cyclists changing position, vehicles emerging from junctions, or traffic slowing suddenly ahead.A developing hazard is something that may cause you to slow down, stop, change direction, or take extra care. The earlier you recognise the risk, the safer your response will be.This practice test helps you improve your observation, anticipation, and road awareness before moving on to official-style video hazard perception clips.how early you should react.
