Crash barriers are very important on the road since they prevent vehicles from leaving the road or careering onto the opposite side.

The barriers work well, but they are often the reason for pile-ups because they completely stop vehicles in their tracks.

In the video below you will see new barriers that are currently being tested which could save the lives of many people.

The collision is completely absorbed thanks to plastic rollers that rotate on contact, which also means the vehicle doesn't come to an immediate halt.

If the results of these new barrier tests are positive, we could see a significant change on our roads and the more traditional roadside barriers replaced.

What do you think of this idea?
