We've updated the hazard perception test for a smoother, more modern, experience. You'll notice that it now works like the mobile app.
Previously you would need to manually work through a long list of clips - and keep track of the ones that you'd already seen. The new player replaces this with a simple "Start" button that will automatically choose a clip that you haven't already seen.
Note that the new hazard perception player doesn't have a mock test option - however you can simulate a mock test and play a sequence of clips by clicking the "Next Clip" button. This will auto-select another clip that they haven't seen and will be very similar to a mock test.
