In T2S Ibérica, we have two types of impact attenuators: parallel and non-parallel. The first are those that are placed at highway intersections, highway exits and areas with high risk of accidents. Through them, it seeks to absorb the energy of the impact, with the aim of taking care of the life of the driver and the rest of the occupants of the vehicle. The non-parallel impact attenuator, on the other hand, offers the same characteristics as the parallel, but also redirects the vehicle away from danger.

Both the parallel and non-parallel attenuators comply with EN1317-3, as they have been tested at the Transport Research Laboratory, UK, as a redirecting impact attenuator for the maximum speed of 100 km/h. Additionally, so that they can fully meet the definition of impact attenuator, Shindo conducted further testing for the 110 km/h, 80 km/h and 50 km/h models.

Among the advantages shared by both types of impact attenuators are the following: they redirect the vehicle after impact, the panels can be changed quickly after an impact, they are highly visible pieces both day and night and have a refined design.
