What are the benefits?
Black boxes, which are about the size of a mobile phone, or equivalent apps that are now available, monitor your driving using GPS positioning and a motion sensor. They look at a variety of factors to determine if the car is being driven safely, and share this information with your insurer, with the potential for them to lower your premium at renewal time if you’ve driven well.
Your black box will pick up on the usual good driving traits such as avoiding aggressive acceleration and braking, as well as sticking to the speed limit, and relay these back to record your driving style. Other things like the number of miles you do and what time of day you use your car may also be reviewed.
This is supposed to generate a more accurate risk profile than the traditional method of just name, age and post code, which could potentially help to lower your premium at renewal time if you’ve shown yourself to be a safe driver. You can also view the information as you go along so you can make any changes to your driving so you can try to improve your risk profile.
