The test consists of 14 CGI video clips showing everyday road scenes filmed from a vehicle’s perspective. You need to watch the screen and click your mouse whenever you spot a developing hazard. 13 of the clips contain a single developing hazard. One clip contains two hazards.

The sooner you spot the hazard and click, the more points you score (from a maximum of 5 down to 1 point per hazard). There’s a total of 15 scorable hazards with a possible maximum score of 75.
