In addition to negative events, your trip score considers other factors, such as trip duration and smooth maneuvering. Even when no negative events are reported, these other factors impact your score. For example, there may not have been sufficient evidence of smooth maneuvering during your trip, or the duration of your trip may not have been long enough to accumulate enough events to earn a lower risk rating.
