This paper introduces a collision avoidance technique for Vehicular Ad hoc Networks (VANETs). An alarm is generated as a warning by the adjacent vehicle depending upon the active speed of impact (ASI) a vehicle expects to encounter after both the adjacent vehicles expect to apply brakes, while in full throttle exactly at the same time. A novel technique of measuring the vehicles' stopping time is introduced by manipulation of co-efficient of decreasing speed (CODS) by the receiving vehicle. Depending upon the received information of CODS, initial speed and other associated factors, the vehicle is given a pre-emptive signal to maintain a safety margin by decreasing or increasing the current vehicle speed. An efficient data packet protocol known as Adjacent Vehicle Collision Avoidance version 1.0 (AVCA ver 1) is introduced in order to update the receiving vehicle with minimum possible data-rate and the requisite amount of data.
