Abstract
Methods and apparatus are provided for protecting an unattended parked vehicle from being impacted by a moving vehicle under control of a driver. The apparatus comprises a detection and alarm system built into the unattended parked vehicle. When a moving vehicle comes within a predetermined distance from the unattended parked vehicle, the apparatus senses the presence of the moving vehicle and activates the alarm system. If the moving vehicle continues to approach the unattended parked vehicle, the activated alarm signals are increased in intensity. Typically, the alarm signals would be in the form of lights flashing and/or horn blowing, or any appropriate combination of audible and visual signals.
