The present invention relates to a device for detecting the distance to the vehicle present in the lane to change the direction of the vehicle to guide the safety by voice, in particular, a direction indicator light switch for operating the direction indicator light ( 10); A distance detector 20 installed at left and right sides of the vehicle and operated by a predetermined control signal to detect a distance to the vehicle existing in a lane to enter; A speaker 50; A voice synthesizer 40 which is operated by a predetermined control signal and outputs information of lanes to be entered as voice; When the direction indicator signal is applied from the direction indicator operation switch 10 by being connected to the signal output terminal of the direction indicator operation switch 10 and the distance detection unit 20 and the control signal input terminal of the voice synthesis device 40. The vehicle direction switching comprises a microcomputer 30 which analyzes a signal of a distance applied from the distance detector 20 to determine whether the lane to be entered is safe to enter and outputs a signal indicating this. City safety distance voice guidance device.;The present invention, when the driver operates the direction light to change the direction of the vehicle, because it detects the distance to the vehicle existing in the lane to enter through the distance detection unit by voice to inform whether the entrance safety, The effect is to be able to change direction safely and easily.
