A method and system for detecting a vehicle impact and automatically requesting emergency assistance is provided. The system comprises multiple impact sensors located on the vehicle. The impact sensors are configured to communicate with each other as well as with a main control unit.

A vehicle hazard alert assembly for increasing safety during an automobile accident includes a plug is electrically coupled to an OBD-II port in a vehicle. A motion sensing unit is electrically coupled to the plug and the motions sensing unit includes an accelerometer. Thus, the motion sensing unit can sense acceleration and deceleration of the vehicle. Moreover, the motion sensing unit communicates an alert signal to the plug when the motion sensing unit senses motion of the vehicle that is consistent with collision avoidance maneuvers. The plug communicates the alert signal to the computer module thereby facilitating the computer module to turn on the hazard lights of the vehicle. In this way the motion sensing unit alerts oncoming motorists of a potential collision hazard.
