Test your driving skills with the free Aviva Drive app and you could save up to 20% on your comprehensive car insurance. 30% qualified for the maximum saving of 20%* The app uses your phone's GPS to track your driving over 200 miles. Earn driving behaviour badges and share your progress on Facebook and Twitter. Once you’ve completed 200 miles, you’ll get an individual driving score between 0-10 (10 being the safest). We’ll give you driving feedback and calculate your personal Aviva Drive discount. Optimum accuracy - Some things affect the precision of GPS on your phone, for the most accurate score we recommend you use an in-car cradle, or place your phone in a stable position. We won’t use GPS data which could be unreliable, you may find the mileage recorded by the app for some journeys is less than the actual mileage you’ve driven. Battery usage - GPS requires battery power. If you’re planning a long journey, consider using an in-car charger Low scores - A score of 3.1 or above recognises your safer driving behaviour and is rewarded with a discount. The safest drivers could get a discount of up to 20%. Aviva won’t penalise drivers with lower scores. Our competitive standard premium will still be available, but without the Aviva Drive discount.
