They are protective systems antisalida which started to be used from 1972. They are manufactured in two parts. The top is a longitudinal strip of 3 mm thick galvanized steel; the other part is a steel profile clamping in the form of T or H fixed on the ground that keeps the longitudinal stripes United among themselves. This protection system was devised, reportedly thinking only in motor vehicles with a body of four or more wheels, and is effective to withstand the direct or indirect impact at certain speeds, but at once constitutes a clear risk element for bikers. And it is that you for accidents of motorcycles where the main body is none other than the human body itself, bumping into this type of protections causes the body of the driver and/or passenger suffer fatal consequences to your health in these cases, in which the driver leaves fired, he slips on the tarmac and goes under the bed rail, being metal and T-shaped parts to act as blades that produce serious injuries and amputations. Its regulations. These StumbleUpon began to settle in 1972.
In 1997 Congress of Deputies approved a proposition not of law which required that in certain black spots of special danger to take place performances of substitution or protection of the vertical elements. The last regulation corresponds to 2004. That year approved the order Circular 18/2004, which entered into force on 10 January 2005. It prohibits the use of double T systems and is obliged, on the one hand, to install alternative or, on the other hand, systems to protect poles from models of double T who are still on the roads. As a result developed a standard (UNE 135900) that evaluates the behavior of systems for protection of motorcyclists in the parapets and safety barriers.
