Embodiments are directed to methods and apparatuses for wireless vehicular communications involving retransmission of messages. A method for communicating by vehicular communications circuitry of a device includes, in a wireless communications network in which a message is broadcasted by vehicular communications circuitry of a device for asynchronous receptions by other circuitry in one or more devices configured to wirelessly communicate according to a communications protocol, monitoring a channel busy ratio associated with channels in a designated range of frequency pertaining to the wireless communications network. The method further includes assessing whether to retransmit the message as a function of the channel busy ratio, and in response to the channel busy ratio being outside a threshold, retransmitting the message according to the communications protocol.
