A noise barrier is located in the immediate vicinity of the road and it is important that the barrier does not cause injuries or severe damage in case of a collision.  Any road equipment located in the immediate surroundings of the road usually must be either safe to road users or protected by a safety barrier. There are international safety standards for noise barriers but they are somewhat imprecise regarding crash safety. In Sweden, safety barriers, lighting columns etc. are crash tested in accordance with international standards but noise barriers are normally not crash tested. Even though the noise barrier has many visual similarities with a safety barrier the noise barrier is not necessarily constructed to break or redirect an errant vehicle. We are, in this case, only discussing the issue if the noise barrier is dangerous in case of an impact. The purpose of this study is to evaluate the safety of a wooden non-rigid crash tests noise barrier. The results show that there was no intrusion into the occupant compartment in any of the tests. On the other hand major wooden pieces flew over a large area as a result of the impact. The top beam is also very rigid and proposes a safety hazard to occupants of high vehicles such as buses and lorries. Occupants in high vehicles, unprotected road users and people living near the road are being exposed to a greater risk with the noise barrier compared to an ordinary safety barrier. This has to be taken into account when decisions regarding noise protection are taken. A noise barrier also creates a safety hazard that can not be evaluated by traditional crash testing. The area on the side of the road is normally less attractive both due to the noise and the immediate presence of the vehicles and as a result there are very few people there.
