How do we calculate your driver score?

The driver score is the most important feature of the Zego Sense app. It allows you to understand how well you’ve been driving, so that you can make improvements in order to receive a reduced premium at renewal. The better you drive, the more you save - it’s as simple as that. But how exactly is your driver score calculated?

Sense uses your phone’s inbuilt sensors

The Zego Sense app uses location and motion data from your phone’s sensors to monitor your driving behaviours whenever you drive. We now monitor four key factors:

Acceleration: How smoothly you accelerate.

Braking: How gently you stop.

Cornering: How carefully you handle turns.

Speeding: How well you stay within the speed limits.

The Sense app creates a score that reflects your driving habits over time and compiles this data to produce your driver score on a rolling basis.

Your score is an average over time

Your score is a reflection of how well you drive over an extended period of time, so it won’t be skewed by one moment or even one day. The app also understands when you’re driving vs when you’re a passenger in someone else’s vehicle, so you don’t have to worry about other people’s behaviour affecting your score.

Your score may change even if you don’t drive for a few days

Note that since your score always reflects an average of your driving in the most recent weeks, you might see changes even if you haven’t driven for a couple of days as the window of relevant data progresses. However, before you can get a score, you’ll need to complete at least 5 trips and drive 62 miles (100km) in the past 35 days.
