A warming device for car driving is proposed in this paper,which includes support rods and warning plates.In this device,several display screens are insalled on one side of the warning panel.Indicator lights are set on the display screen.A waning board is mounted on the top box.Several radar detectors are mounted on one side of the top box,and the radar detectors orrespond to the display screens.Several waming lights are installed on the top box,and the waning lights orespond to sevenl radar detectors.The sliding side of the support rod cleans the unit.The change of positions of the indicator lights based on the radar detectors will be rellected on the display screens,which allows drivers to understand the situation of the road.Therefore,they can prepare for changing lanes and overtaking,and understand the position and speed of all vehicles in this road section in advance. 展开更多
