Achieving a great trip score is the result of the very best (safest) driving behaviors. A great score generally requires an absence of any ‘negative’ behaviors, such as hard braking, hard cornering, hard acceleration, speeding, or cellphone distraction.
In addition, in order to achieve a great score, you must exhibit ‘positive’ driving behaviors such as smooth stops and turns - where there is a high proportion of these smooth maneuvers out of all maneuvers during the trip.
The algorithm will record and categorize all maneuvers such as starts, stops and turns irrespective of the specifics of a given route and incorporates this information into the calculation of the FICO® Safe Driving Score. All else held equal, the more smooth maneuvers a trip has, the better. More specifically, the scoring algorithm will take into account the proportion of these smooth maneuvers (out of all maneuvers of a similar type).
Example: A trip with 3 smooth stops out of 12 stops total will generally score lower than a similar trip with 2 smooth stops out of 3 total.
