Pass Plus is an extra driving qualification, over and above the driver’s test which gets you your licence. It involves gaining practical experience dealing with situations which most students haven’t covered in standard driving lessons. It also includes testing on skills they wouldn’t have been tested on before getting their licence.
The theory is then that you’ll be less likely to be involved an accident on the road, which will not only keep you safe, but could mean you are less of a risk to your insurer. And if your insurer sees you as a less of a risk, that could, result in lower premiums.
