Safety Event Review is an optional add-on service for large fleets of 500 vehicles or more. With this service, Samsara's specialized review team streamlines the Safety Event Review process by performing the initial event review, filtering, and tagging safety events for your fleet. Samsara reviewers will review safety events within 24 hours and identify incidents that require coaching so that you can focus on coaching drivers.
With the Safety Event Review service, only crash events are automatically routed to the Safety Inbox. These events will have a Needs Review Status. All other events are routed to a Samsara reviewer for analysis. When a reviewer assesses a safety event, the reviewer raises only highly-relevant, coachable events to the Safety Inbox. If an event doesn’t meet the threshold of coachable behavior, the reviewer will dismiss the event. As a result, you will see fewer events than you would without the Safety Event Review service.
Safety event labels can help you to identify the behavior for which a driver needs coaching. There are two types of event labels: automatically assigned labels and labels assigned by a Samsara reviewer. Automatically assigned labels include events, such as crashes, that have defined threshold settings to trigger assignment. Additional supplemental labels can also be assigned by reviewers after reviewing a safety event.

The following table describes the event labels that identify behaviors that require coaching:
Event Label |
Coachable Event Definitions |
---|---|
Automatically detected events |
|
Crash |
Samsara automatically detects crashes when g-force passes a crash threshold. Automatically detected crash events skip manual triage for safety events and are automatically routed to the Safety Inbox as |
Harsh Accel |
The vehicle accelerated drastically or abruptly (16+ mph in ≤ 2 seconds). |
Harsh Brake |
The vehicle slowed down drastically or abruptly (16+ mph in ≤ 2 seconds). |
Harsh Turn |
The vehicle turned drastically or abruptly (19+ mph midpoint of turn). |
Following Distance |
An unsafe following distance (<1 second) from the vehicle directly in front was detected. If a driver was cut off by another vehicle or the vanishing point is miscalibrated, the Samsara reviewer will not route the event to your Safety Inbox for review. |
Inattentive Driving |
Driver was looking down or at an object (visible or not) 3+ times in rapid succession for 50% or more of the video. If the driver's eyes remain focused on the road for the duration of the detection, such as lowering head to scratch ear while focusing on the road, the Samsara reviewer will not route the event to your Safety Inbox for review. |
Rolling Stop |
The vehicle did not slow to 0 mph before entering an intersection or impeded a pedestrian’s ability to cross within a crosswalk. |
Forward Collision Warning |
An imminent rear end collision was detected. After coming to a complete stop, driver was 5ft or less from the vehicle in front. |
Supplemental labels added by reviewers |
|
Defensive Driving |
The driver reacted within 2 seconds to a potential safety event caused by an unexpected occurrence, such as a sudden change in traffic lights or the behavior of another individual. If the Samsara reviewer identifies a Defensive Driving behavior, the event is raised to the Safety Inbox with a |
Did Not Yield |
The driver failed to allow merging or right-of-way to a person or vehicle if the current driving conditions would have allowed it. NoteDoes not apply to YIELD signage. |
Drowsy |
Driver behavior that commonly indicates drowsiness was detected. Examples include the driver's head nodding with closing eyes or a combination of head shaking, face slapping, or eye rubbing. |
Lane Departure |
Any erratic, swaying driving that resulted in an inability to maintain position in a lane. Additionally, the center of the vehicle clearly crossed a line continuously for 3+ seconds, completed an illegal U-turn, or drove through marked lines in a parking lot. NoteExcludes a legal lane change, necessary wide turns, and narrow roads. |
Late Response |
The driver did not react to surrounding conditions (brake lights, traffic light, or slowdowns) within 2 seconds. |
Mobile Usage |
The driver held or handled a mobile device, laptop computer, or tablet. The Samsara reviewer detected multiple holding positions including in the lap. |
Near Collision |
The vehicle came close to colliding with an object, regardless of whether the object was moving. |
No Seatbelt |
The driver did not have the seatbelt buckled or correctly fastened. For example, Samsara will raise a No Seatbelt event when the seatbelt is buckled but the driver is sitting on the strap or does not have it across the chest. |
Speeding |
The vehicle speed was more than 19 mph in a parking lot or more than 6 mph over either the posted limit or yellow speed advisory sign. |
Ran Red Light |
The vehicle entered an intersection during a detected red light or impeded pedestrian ability to cross within a crosswalk. |
Obstructed Camera |
Interior-facing camera: The driver face, including eyes and mouth, were blocked from the interior-facing camera. Interior view was more than 80% obstructed. Road-facing camera: The road was blocked and not clearly visible from the road-facing camera. Road view was more than 80% obstructed. |
To help tune the review process, you can provide feedback to Samsara on the accuracy of event labels and detection.
When a reviewer misclassifies a safety event and assigns an incorrect label:
-
From the Safety Inbox view of an event, hover over the video.
Samsara displays a popup for you to provide feedback.
-
If the event is accurate, click the thumbs up icon.
-
If the event is inaccurate either in the detection or the label, select the thumbs down icon.
Samsara displays a feedback form that you can use to provide feedback. The options vary depending on the event type.
-
Choose the option that best represents your assessment of what triggered the safety event.
If the options don't reflect your assessment, choose Other and provide further explanation or details.
-
Submit your response. If you only want to submit your rating and do not want to provide additional details, you can Dismiss and submit.
Your assessment helps Samsara improve the detection capabilities.
