Disclosed is a vehicle, which senses a speed of the vehicle using a speed sensor unit and also senses a vehicle-to-vehicle distance between the vehicle and a first vehicle immediately ahead of the vehicle using a distance sensor unit and then determines a state of the vehicle based on the speed of the vehicle and the vehicle-to-vehicle distance. In this case, when the vehicle is in a first state, the vehicle displays a first image captured by a first camera unit on a first display unit. In addition, when the vehicle is in a second state, the vehicle displays a second image captured by a second camera unit on the first display unit. Here, the second camera unit is a camera unit stalled in a second vehicle, and the second vehicle being any one of one or more vehicles ahead of the vehicle.
