A driver alert arrangement for a motor vehicle includes a sensor detecting that the motor vehicle is in motion and transmitting a signal indicative of whether the motor vehicle is in motion. A driver monitoring camera captures images of a human driver of the motor vehicle. An electronic processor is communicatively coupled to the sensor, the driver monitoring camera, and to a user interface. The electronic processor receives the signal from the sensor, receives the images captured by the driver monitoring camera, determines from the images where the driver is looking, and alerts the driver via the user interface that the motor vehicle is in motion. The alerting is dependent upon the signal and where the driver is looking.
