Samsara Safety Event Review Service

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 Needs Review. If Samsara did not automatically identify the event as a crash, such as events with a low g-force or side swipe, the Samsara reviewer will manually add the crash label and route it to your Safety Inbox for your review.

Harsh Accel

The vehicle accelerated drastically or abruptly (16+ mph in ≤ 2 seconds). Harsh Accel events are routed for review only if the Samsara reviewer identifies a second coachable behavior that occurred during the time of the event.

Harsh Brake

The vehicle slowed down drastically or abruptly (16+ mph in ≤ 2 seconds). Harsh Brake events are routed for review only if the Samsara reviewer identifies a second coachable behavior that occurred during the time of the event.

Harsh Turn

The vehicle turned drastically or abruptly (19+ mph midpoint of turn). Harsh Turn events are routed for review only if the Samsara reviewer identifies a second coachable behavior that occurred during the time of the event.

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 Needs Recognition status and an event label of Defensive Driving.

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.

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.

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.
