In-cab audio alerts help your drivers respond to real-time events—whether it’s a harsh brake, unbuckled seatbelt, or extended idling. These alerts can use a simple tone or a voice message to coach drivers toward safer, more compliant behavior. When configured, the same audio alert settings also apply to Nudges, ensuring consistent in-cab feedback across supported detections.
You enable in-cab audio alerts at the fleet or individual vehicle level, but each supported event must also be enabled individually. VG-detected events are enabled from the Voice Coaching setting. In-cab audio alerts for AI-detected events are enabled in the configuration for each detection type.
In-cab audio alerts are supported with the following:
-
Dash Cams: CM12, CM22, CM31, CM32, CM33, CM34
The Samsara Dash Cam provides in-cab alerts with either a tone or voice coaching to notify drivers of detected events.
-
Vehicle Gateways: VG34, VG54, VG55
-
Firmware: VG version 33.1 or later, CM version 40 or later
-
Languages: English (US/UK), Dutch, French, German, Italian, Spanish
-
Connectivity: The VG must be online. If offline, alert delivery expires after 15 minutes.
You can define in-cab audio alert behavior from the Voice Coaching setting (fleet-wide, individual vehicles). For VG-detected safety and operational events, enabling audio alerts in this setting activates in-cab alerts. For AI-detected events, in-cab audio alerts occur only when they are enabled in the configuration for each detection.
