To keep things real, Tag N Go only uses the amount of time on the trip that the driver actually had the opportunity to speed. This is called free flow time. If a total trip lasted 40 minutes, but 5 minutes were spent idling in the driveway and 5 minutes were spent stopped in traffic, DriveScore™ considers this only a 30 minute trip because that is the amount of time the driver had the opportunity to choose his own speed. Only speeding 5 mph or more over the speed limit is considered as speeding in the Tag N Go calculation.
