VEHICULAR INTERIOR REARVIEW MIRROR ASSEMBLY WITH DRIVER MONITORING CAMERA AND DRIVER BREATH ANALYZER

A vehicular alcohol sensing system includes an air sensing device disposed at a vehicular component disposed at an interior portion of a vehicle. The air sensing device captures sensor data representative of a sample of air at the vehicular component. A driver monitoring camera is disposed in the vehicle and captures image data representative of at least a head region of a driver of the vehicle. The vehicular alcohol sensing system, based on processing by a data processor of sensor data captured by the air sensing device and based on processing by an image processor of image data captured by the driver monitoring camera, determines an alcohol level of the driver's breath. The vehicular alcohol sensing system, responsive to determining that the alcohol level of the driver's breath is above a threshold alcohol level, prevents operation of the vehicle.
