Stopgate is used before the traffic control road to remind the road is closed,it can not only guide the vehicle to drive on the right route,but also force to stop the error vehicles from approaching the control road.

When the vehicle hits stopgate,Y-shaped metal plate will rotate to lift the front wheels of vehicle,which is helpful for stopping the vehicle.The impact force will be transmitted to the plates on the ground,then the friction between the plates and ground will stop the vehicle,so as to effectively reduce the damage of the traffic accidents.
