By default, the following speeding severity levels define thresholds for classifying speeding and aggregate all events in reports regardless of their duration. These thresholds, along with whether an event impacts the safety score based on total duration or only those exceeding a minimum duration, can be customized in the Speeding Settings.
Speed severity is determined by the duration of time the driver spends at a speed (mph or kmph) over the speed limit. The duration ends when the driver returns to a speed that is at or below the speed limit. If a speeding instance is above the speeding thresholds, the event impacts the safety score and also counts as a speeding event surfaced in the Speeding Trends report.
If a speeding event does not exceed the speeding threshold, the amount of time spent above the speed limit accumulates in its corresponding severity level and impacts the driver safety score. For example, using the default speeding settings, if a driver is traveling 6 mph above the speed limit for 30 seconds, the time would count as moderate speeding time in the Speeding Reports, but would not count as a speeding event.
By default, the following speeding settings are configured for each severity level:
US fleets:
-
Light: Less than 6 mph above the speed limit for a duration of at least 60 seconds
-
Moderate: 6-10 mph above the speed limit for a duration of at least 60 seconds
-
Heavy: 11-15 mph above the speed limit for a duration of at least 60 seconds
-
Severe: More than 15 mph above the speed limit for a duration of at least 20 seconds
Non-US fleets:
-
Light: Less than 11% above the speed limit for a duration of at least 60 seconds
-
Moderate: 11%-20% above the speed limit for a duration of at least 60 seconds
-
Heavy: 21%-30% above the speed limit for a duration of at least 60 seconds
-
Severe: More than 30% above the speed limit for a duration of at least 20 seconds
