Pass Plus is a practical training course that takes at least 6 hours and is for drivers to improve their skills and drive more safely. It can be taken at any time although it should be most useful to new drivers in the year after passing their test. It may help you get a car insurance discount if you successfully complete the course.
Congratulations - you have passed your test. Why not improve your skills and improve your driving by investing in a Motorway driving lesson, or lessons.
