To keep drivers, the goods and passengers they are transporting, and other vehicles on the road safe, Samsara's Vehicle Gateways (VGs) and cameras will document Harsh Events in your Safety Inbox, Safety Report, and Alerts page. You can use this information to coach drivers on improving unsafe driving behaviors and get data on what factors may have caused a Harsh Event.
What is a Harsh Event?
Harsh Events can include:
- Harsh braking
- Harsh accelerations
- Harsh turns
When a Harsh Event occurs, the VG records the time, driver, vehicle, and location of the event as well as additional data about speed and direction.
The event can then be found in three different places:
- Safety Inbox
- Safety Report
- Alerts Page
How Harsh Events Are Identified
Harsh Events are triggered when the VG's built-in accelerometer detects that your vehicle has surpassed a G-force threshold. These are the default sensitivity parameters and sustained acceleration rates for each type of vehicle:
- Heavy Duty: 0.35g (most sensitive)
- Light Duty: 0.4g
- Passenger Car: 0.6g (least sensitive)
Manually Set Vehicle Type for Harsh Event Detection
By default, the vehicle type is inferred by the VG, but you can also manually set this from the vehicle settings in the dashboard by following these steps:
- Settings > Gateways > Click three dots next to your VG's name
- Settings in the drop-down menu
- Scroll down to Harsh Event Detection Settings
- Select the vehicle type
- Click Save
Customizing Harsh Event Sensitivity
You can navigate to Settings > Safety > Harsh Events to configure the Harsh Event Sensitivity of your fleet.
Harsh Event Sensitivity is set by vehicle type and event type. As you adjust the sliders, you can see the raw values of the thresholds update for each vehicle type.
You can also see Advanced Options by turning the Toggle On (it will turn green). Here you will be able to specify parameters for each type of vehicle and each type of Harsh Event.
Additionally, if you check Legacy Setting, the settings will default to the parameters above:
- Heavy Duty: 0.35g
- Light Duty: 0.4g
- Passenger: 0.6g
If a Samsara dash cam is also installed in your vehicle, it will automatically upload a 10-second video of the Harsh Event that can be reviewed in your Safety Inbox. An accurate and detailed Safety Inbox is important to productive safety review and driver coaching.
To view your Safety Inbox, navigate to the Safety Icon on the left-hand side > Safety:
Your Safety Inbox has four tabs at the top:
Labeling Harsh Events in Your Safety Inbox
Full Admins can add and remove automated labels on events in their Safety Inbox. Removing automated labels or adding custom labels helps improve Samsara’s automatic detection of these types of harsh events.
To add or remove labels for Harsh Events:
- Navigate to Safety > Safety Inbox
- Select any event by clicking on it
- You can add a label to the event by clicking Add and selecting an option from the dropdown
- You can remove a label from the event by clicking on the X next to the label
Categories and Labels
Check out this table for more labels you can use in your Safety Inbox:
|Harsh Driving||Crash, Harsh Brake, Harsh Turn, Harsh Acceleration|
|Driver Risk||Distracted, Drowsy, Mobile Usage, No Seatbelt, Late Response|
|Road Risk||Did Not Yield, Near Collision, Speeding, Lane Departure|
|Following Distance||Tailgating, Following of 3-4s, Following of 1-2s|
|Other||Defensive Driving, Obstructed Camera|
Commenting on Harsh Events
As a Fleet Admin, you can add comments to events in your Safety Inbox. The comment section will allow you to leave notes for a later follow-up or clarification on the harsh event.
Users must have Full Admin permissions with Dash Cam Access in order to write comments. Full and read-only admins with Dash Cam access will also be able to view previously made comments.
First, navigate to the Safety Inbox: Fleet > Safety and select any Harsh Event incident.
Below the video and details of the harsh event, you will find an Activity section in which you will be able to leave comments. The most recent comments will be displayed at the top of the thread.
You can also bring someone's attention to an incident by typing @[name] to search for your colleagues.
