An apparatus includes a vehicle position module that determines a position of each proximal vehicle with respect to a user's vehicle. Each proximal vehicle is positioned in relation to the user's vehicle without another vehicle between the proximal vehicle and the user's vehicle. A vehicle network module establishes a communication link between the user's vehicle and the proximal vehicles. A message receiver module receives an alert message from a front proximal vehicle in front of the user's vehicle in response to the front proximal vehicle sending the alert message. A message transmitter module transmits an alert message to a rear proximal vehicle traveling behind the user's vehicle. The transmitted alert message includes an alert message received from a front proximal vehicle and/or an alert message generated within the user's vehicle. An alert action module takes an action with respect to the user's vehicle in response to receiving an alert message.
