Overview: Three new celebrities join Driving School, hoping to swap their L-plates for passed in just four days. Comedian Mark Watson, singer Tallia Storm, and Hollyoaks' Ruby O'Donnell are paired with a crack team of driving instructors as they bid to bag a licence. Mark's nerves get the better of him behind the wheel. Tallia gets off to a confident start, but struggles with her clutch. Ruby spends her first day tackling hill starts and roundabouts.
