On the ring road there are new fences

According to tut.by, these front guardrails, which when hit in them, extinguish the energy of the car. In the future, such constructions may appear everywhere.

Front fences serve for preventing severe consequences when a car collides with road structures, thanks to them, the car does not receive critical damage when hitting, and the driver and passengers — serious injuries. They are installed in places where traffic flows are separated, in front of massive obstacles, bridge supports and other dangerous road sections.

How they work: in a frontal impact, the car collides with the plate, and it moves the internal parts of the system, deforms them, the outer beams of the fence are folded like a telescope.
