What is Event Severity?

Updated

Introduction

Once enabled through company settings, Event Severity automatically assigns a severity level to safety events. Read below to learn how severity is determined for safety events.

How Event Severity helps you

Event Severity helps Fleet Managers to prioritize which safety events to review first.

Event Severity overview

When enabled, safety events will have one of four available severity values (critical, high, medium, low) assigned. The table below provides a detailed description of severity definitions for each safety event.

Safety eventSeverity typeSeverity definition
CollisionCriticalCollisions are always critical severity events.
Near CollisionHighNear collisions are always high severity events.
SmokingHighSmoking severity will always be marked as high.
Driver captureHighDriver captures are always high severity events because the driver is proactively sharing footage.
Forward Collision WarningHighForward Collision Warnings are always high severity events.
Unsafe ParkingHighUnsafe parking events are always high severity.
Hard BrakingLowVehicle deceleration intensity between 0.34g and 0.36g
MediumVehicle deceleration intensity between 0.36g and 0.40g
HighVehicle deceleration intensity above 0.40g
Hard AccelerationLowOur AI algorithm determines the event's severity using unsafe driver behavior and telematics data.
MediumOur AI algorithm determines the event's severity using unsafe driver behavior and telematics data.
HighOur AI algorithm determines the event's severity using unsafe driver behavior and telematics data.
Hard CorneringLowOur AI algorithm determined this event's severity using unsafe driver behavior and telematics data.
MediumOur AI algorithm determined this event's severity using unsafe driver behavior and telematics data.
HighOur AI algorithm determined this event's severity using unsafe driver behavior and telematics data.

MediumDriver does not maintain a safe following distance while changing lanes & driving between 30-45 mph.
HighDriver does not maintain a safe following distance while changing lanes & driving over 45 mph.
Obstructed CameraLowVehicle travels with an obstructed camera between 0-15 mph which may have prevented the detection of additional unsafe behaviors.
MediumVehicle travels with an obstructed camera between 15-45 mph which may have prevented the detection of additional unsafe behaviors.
HighVehicle travels with an obstructed camera over 45 mph which may have prevented the detection of additional unsafe behaviors.
DrowsinessLowDriver appears drowsy or fatigued while driving between 10-25 mph.
MediumDriver appears drowsy or fatigued while driving between 25-45 mph.
HighDriver appears drowsy or fatigued while driving above 45 mph.
Forward ParkingLowMax reverse speed is less than 2 mph
MediumMax reverse speed 2–5 mph
HighMax reverse speed is more than 5 mph
Lane swervingLowSpeed range is 35-45 mph
MediumSpeed range is 45-55 mph
HighSpeed range is 55+ mph

Note:

  1. Lane cutoff and Ran red light events do not have any severity assigned to them because they are tagged by the Safety review team. They inherit the severity of the underlying safety event generated by Motive devices.
  2. When one event has multiple Unsafe behaviors tagged to it, the severity for that event is calculated based on the maximum of the severities of the multiple unsafe behaviors tagged to the event.
  3. When you change the severity from the dashboard, then you will see the same severity across the dashboard for that event. You will also notice such changes in the severity tool tips in the Safety events listing and events details page, where the tool tip reads “The severity of this event was manually changed by a fleet manager from your company.”
  4. When severity is pending, it means that Motive is still analyzing the severity and has not allocated any severity to the event yet. In such cases, you will notice that the tooltip reads “A severity level will be assigned once Motive analyzes this event.”
