In VANET, vehicles are move very fast as a consequence intermittent connectivity occurs frequently. In this delay-tolerant situation, the emergency rescue message broadcast is an extremely challenging task. The proposed routing protocol REMD give a solution to the problem. REMD follow the store carry forward method and flooding based message forwarding method. This paper expresses rapid emergency message dissemination routing in delay tolerant network called REMD Protocol. In this protocol, the source vehicle broadcast emergency message to the presented all neighbour vehicles in its communication range. The sender vehicle allocates message replicas and message time to live to the neighbour vehicles based on the corresponding vehicles credence value. Each vehicle credence value is calculated from their Visited Level Estimation (VLE) and Destination Reaches Level Estimation (DLE) values.
