Samsara supports the ability to create alerts based on your Driver's vehicle engine idling time.
To create a Vehicle Engine Idle alert, navigate to Alerts > Configure > Vehicle Engine Idle
You can customize which vehicles to set an alert for, how much idle time should pass before you receive an alert, and what time frame you'd like to receive alerts.
You can view alerts by navigating to Alerts > Incidents
