The first series of tests made in 1977 have been presented in VTI Report No. 158. In 1980 a major change in the profile of the barrier and its connection system was made. This report describes tests with this new disign at speeds up to 109 kmph, impact angles u to 25o and vehicle masses up to 2 040 kg. The conclusion from these tests is that the new design offers a considerably better safety performance than the old one. The structural adequancy and the vehicle trajectory hazard requirements as specified in the USA seem to be met.
