Speed limiter, 40 x 50 x 4.5 cm, black color

The speed limiter 40 x 50 x 4.5 cm is placed on the road to make it possible to limit the speed, i.e. reduce it to the level of 15-30 km/h. The material is quite resistant, with phosphorescent beacons for the night. It is also used to regulate traffic in certain areas by maintaining a constant speed.
