Provided are a traveling distance prompt device and a method thereof. The traveling distance prompt device is arranged on the first vehicle to calculate a travelling distance between the first vehicle and the second vehicle. The device comprises an image capturing module, a prompt module and a processing module. The image capturing module is used for obtaining vehicle images of the second vehicle. The processing module is coupled with the image capturing module and the prompt module. The processing module is used for capturing the license plate image in the vehicle images and calculating the travelling distance between the first vehicle and the second vehicle according to the image characteristics of the license plate image. The processing module is used for calculating a safe distance according to the travelling speed of the first vehicle and the image characteristics, determining whether the travelling distance is more than the safe distance and controlling the prompt module to output prompt information correspondingly. The traveling distance prompt device can determine whether the traveling distance is safe rapidly and accurately through simple hardware configuration.
