How do you measure speed, acceleration, braking and cornering?

We assess these areas of your driving with the GPS and accelerometer data from your black box.

We measure acceleration (g-force) using the accelerometer in the box. Acceleration means the rate at which speed changes. So, if your speed increases rapidly over a short period of time, it will mean more acceleration than if you speed up gradually.

Braking also uses your box’s accelerometer data and is basically the opposite of acceleration: the rate at which your car slows down.

Cornering looks at the rate at which your car turns. The 2 main factors that determine the g-force generated when cornering are the angle of the corner and the speed at which your car is travelling. The tighter the corner, the slower you should approach and travel around the bend.

We calculate your speed using the GPS signal transmitted from your box - it’s the rate at which you move from one point to another. That speed is then compared to our database of speed limits across the country. Doing speeds that could get you a speeding ticket and points will affect your driving score.

If you get a Highly Dangerous message:

  1. Your score will be set to zero until after your next quarterly price review - when your score will be reset
  2. You’ll receive the highest increase in price you can for that quarter
  3. We'll call you to talk about your driving, and send you a letter that explains everything
  4. Your policy will be put on review and unless we see a significant improvement in your driving, your insurance will be cancelled
  5. If you then get a second Highly Dangerous message at any time throughout the year, your insurance will be cancelled
Warning: driving at unacceptably high speeds can mean an immediate cancellation of your insurance.
