The invention discloses a road reflection device and relates to the technical field of road reflection devices. The device comprises a sensor, a control device, a drive device and reflection equipment, wherein the sensor is used for collecting passing conditions of cars; the control device controls the reflection effect according to collecting results of the sensor; the drive device is used for driving the reflection equipment and regulating the reflection effect of the reflection equipment; the reflection equipment presents different colors in different states. The reflection device has the advantages that whether the cars pass in the day or at night or not is sensed through the sensor, sensed signals are transmitted to the control device, the control device controls the drive device to drive the reflection equipment according to whether car signals are sensed or not, the reflection equipment presents different colors when the cars pass and when no vehicles pass respectively, so that the device has the function of reminding a driver and reduces the occurrence rate of traffic accidents.
