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 for the rest of the quarter but you'll start the next quarter with a clean slate
  2. You'll get the highest increase you can for that quarter
  3. Your policy will be put on review and unless we see a significant improvement in your driving, your insurance will be cancelled
  4. If you receive a second Highly Dangerous message at any time over the year, your insurance will be cancelled
Warning: driving at unacceptably high speeds or creating an extremely high number of harsh braking or harsh cornering events may lead us to cancel your insurance with us immediately
