The function of impact attenuators is to cushion collisions on the roads, with the aim of helping to reduce the number of victims, injuries, and damage.

Its use is increasingly widespread due to the excellent results that have been proven after years of use and development. Currently, research indicates that 8 out of 10 collision deaths can be avoided against obstacles protected by this mechanism. This is how it is a device with 80% effectiveness, which undoubtedly fulfills its task.

On the other hand, there are internationally renowned companies such as the Transport Research Laboratory of the United Kingdom or Shindo, which have tested the impact attenuators of T2S Ibérica, certifying their compliance with certain regulations, such as EN1317-3, and guaranteeing that they correspond to the definition of impact attenuators for different speeds.
