The article New euro crash barriers claimed to threaten lives (NCE last week) missed the point of the concrete barriers.
Concrete arriers can save lives by containment and preventing the vehicle from passing through or over the barrier into the oncoming flow of traffic, or rebounding into the traffic coming from behind the vehicle.
The concrete barrier described previously in NCE article New crash barrier could cut deaths (NCE 9 September 2004) was designed specifically to do this.
It is therefore unfortunate that the Highways Agency has approved a concrete barrier which is likely to cause the death of occupants together with the occupants of vehicles behind or those on oncoming vehicles in the other carriageway.
