Abstract

A system installed in a resident vehicle monitors a number of operating profile parameters of the resident vehicle as well as data associated with the resident vehicle in relation to a leading or trailing vehicle. A light indicator having a number of lights viewable by a trailing vehicle and/or the driver of the resident vehicle is controlled to provide a warning to indicate that one of the vehicles is tailgating another vehicle and/or closing on another vehicle at a speed that is unsafe. The monitored data is stored in association with the time of occurrence of the data to provide a record thereof. Further, the system can include one or more cameras to provide a digital image of the view in front of the resident vehicle or in back thereof. The images are stored in association with the profile and time of occurrence data to provide a record thereof.
