HAZARD PERCEPTION

Spot the developing hazard

120 real clips, all available during free study. Watch the road, tap when something develops, then see exactly how your timing scored.

Practise a whole set

Choose a generic blind practice set. Scores and timing review stay hidden until all films are complete; unfinished practice can be resumed.

How the practice scoring works

Each authored hazard window has 5 zones. The earliest scores 5 and the latest scores one. Only your best tap on each hazard counts; tapping outside its window scores nothing.

Rapid guessing can void a practice attempt. This app’s guard is a practice rule, not a claim about the examination’s unpublished detection algorithm.

A single-clip result is not a full hazard-perception examination or a readiness prediction. The web player needs a connection; the mobile app can download clips for offline practice.

About the clip library

What is a developing hazard?
Something developing that would make you change speed or direction. A parked car may be a potential hazard; pulling into your path makes it a developing one.
Which clips are free?
All study features are free while the study-progress limit is being set.
Does leaving early affect my score?
No. An attempt is recorded only when the film ends. Playback errors and unfinished films do not become zero-score results.
What syncs between devices?
Your best score and attempt count sync with your account. Detailed tap-by-tap replays currently stay on the phone or browser where you practised.
