The overall FICO® Safe Driving Score is based on a rolling 7-day average. It is recalculated every day using the prior 7 days of data. So, if you have several “Great” trips, which are followed by some “Good” trips, at some point, the “Great” trips will start to drop out of the score calculation and be replaced by the “Good” trips. This means the highest point value scores are being replaced by lower point value scores, which will cause your overall FICO® Safe Driving Score (average) to decrease.
The FICO® Safe Driving Score is determined based on a driver’s driving behaviors where drivers are both rewarded for positive behavior as well as penalized for risky driving behaviors. This level of risk can of course be improved over time by modifying your driving behavior as outlined through Feedback Factors, following instruction providing in Mentor coaching modules, etc.
