A communication system for vehicles includes a first communication device disposed at a first vehicle and a second communication device disposed at a second vehicle. The first communication device wirelessly transmitting data indicative of a predicted path of travel of the first vehicle, and the second communication device receives the transmitted data from the first communication device. A control of the second vehicle processes data received from the first communication device and data indicative of a predicted path of travel of the second vehicle to determine a potential collision between the first vehicle and the second vehicle during a turning maneuver of one of the first and second vehicles toward the other of the first and second vehicles. Responsive to determination of a likelihood of collision between the first vehicle and the second vehicle, the control generates an alert to a driver of the second vehicle.
