In this article experimental results of a car impact into a modified road barrier are presented. For crash tests a modified protection barrier SP-04, composed of guide poles, type B, and bridge posts IPE140, was chosen. The road barrier modification lies in using additional panels absorbing the impact energy. The protective panels, subjected to examination, consisted of a metal or a composite (laminate, glass-polyester) shield in which the f o amed aluminium or polyurethane foam was a filling. The Suzuki Swift car s were prepared for the crash tests. Tests were carried out at the Automotive Industry Institute (PIMOT) in Warsaw, with the use o f a test sample of the road barrier. For the safety sake the car's speed during the experimental examinations was limited to 50 km/h. Moreover, the vehicle hits perpendicularly in a properly modified road barrier's sector. During the test a registration of acceleration was carried out by the acceleration sensors placed in the car (among others in the centre of gravity and over the rear axle of a car). A crash test course of the system C-G was registered with the use of two cameras for fast shooting (Fantom v12). An image was recorded with the resolution of 1280 x 800 pixels and with frequency of 1000 shots per second. The shot exposure time equalled to 250 microseconds.
