The outward-facing dash cam can create a Lane Departure Warning (LDW) safety event if the vehicle crosses a solid yellow or white line, alerting both you and the driver to potentially unsafe driving behavior.
When the dash cam detects an LDW event, it uploads a 10-second video of the detection to the Safety Inbox as a Lane Departure Warning event. By default, LDW events do not impact the driver safety score. To include LDW events in the safety score calculation, configure a weight for the behavior.
The LDW system relies on an outward-facing camera to monitor lane markings. To trigger an LDW event in the Safety Inbox, the system detects when a vehicle traveling at speeds of 35 mph or more crosses a solid yellow or white line.
To optimize the use of LDW and customize it for your fleet, follow these workflows:
-
Review Event Detection Best Practices: For the most accurate AI Event Detection, review the recommendations and best practices for AI Event Detection and Lane Departure Warning.
-
Customize In-Cab Alerts: By default, in-cab alerts are disabled. When you enable and configure Lane Departure Warning, you can optionally enable in-cab audio alerts and Nudges to notify drivers of detections.
-
Set Notification Alerts: In addition to in-cab audio alerts for drivers, you can also configure alerts to receive email notifications or SMS when an LDW event occurs.
Lane Departure Warning can sometimes trigger false positives or inaccurate alerts. If the camera cannot detect lane markings, it will not trigger a warning. To minimize these inaccuracies, ensure the road is clearly visible to the outward-facing dash cam. Address or remove any items that can impair visibility through the windshield, such as dirt, debris, or glare.
After enabling LDW, you can configure the following in-cab driver notifications:
-
In-Cab Audio Alerts: When you enable in-cab audio alerts, the alert type (tone or voice-coaching) reflects the fleet-level Voice Coaching configuration. If voice coaching is selected, an audible return to lane message plays after the thresholds are met.
-
Nudges: When you enable in-cab audio alerts, you can also enable this setting to provide drivers with an opportunity to self-correct their behavior in the moment before their safety scores are impacted. For more information about this settings, see In-Cab Nudges™ (Alerts).
When you configure this detection, you can choose which vehicles this setting applies to:
-
All vehicles: Apply to all vehicles in your fleet (Settings (
) > Safety > AI Event Detection > Lane Departure Warning).
-
Subset of vehicles: Apply to one or more vehicles (for more information, see Safety Settings for Individual Vehicles).
Note
To enable LDW, ensure you have the latest detection versions of Rolling Stops and Following Distance. For more information or to verify your detection version, contact your Customer Success Manager or reach out to Support.
