The present disclosure provides a system for providing a driver of a host vehicle being stopped with a preliminary notification that remote vehicles forming a queue in front of the host vehicle are likely to start moving. The system includes a receiver, a notifying device, a determiner, and a controller. The receiver is configured to receive messages from the remote vehicles through Vehicle-to-Vehicle (V2V) communications. The notifying device is configured to provide the driver with the preliminary notification. The determiner is configured to determine whether a specified vehicle among the remote vehicles other than a preceding vehicle directly ahead of the specified vehicle starts moving based on the messages sent from the specified vehicle. The controller is configured to control the notifying device to provide the preliminary notification when the determiner determines that the specified vehicle starts moving.
