Helen and Rannoch

After two years and over 200 lessons, 21-year-old Rannoch from Edinburgh recently passed his driving test. But there's a problem - his parents are reluctant to let him drive on his own just yet. So Rannoch, who has autism, is going to take a Pass Plus course to perfect his driving skills before being given the keys to the family car.

In Lincoln, 20-year-old Helen has autism and uncontrollable twitches which means she struggles to keep two hands on the wheel, something she will need to conquer if she is to pass her test.
