As a consistent and objective measure of driver risk, the FICO® Safe Driving Score is comprised of variables that evaluate driving behavior across 5 key categories: Acceleration, Braking, Cornering, Distractions, and Speeding. The importance of these categories is not equal. While specific algorithms cannot be disclosed, empirical analyses conducted on millions of trips found that Acceleration and Braking generally have the largest impact on the FICO® Safe Driving Score, followed closely by other negative behaviors, such as Speeding and Distractions.
