As said when I did mine it said to click once u spot a potential hazard that could develop into a hazard and then when it becomes a hazard. Work for me anyways good luck

I loved it especially when he let me loose on the road driving a Honda CB500 deffo sorting my lessons and test for the next couple of weeks Right now to buy a bike lol
