The unfolding disaster on the N7 has got to see a rethink of the culture of driving in Ireland. 40 collisions on the one stretch of road in the matter of a few hours can't be described as anything but a disaster. I hope that those in a critical condition pull through and those seriously injured aren't too badly hurt.
However, we need to be honest enough with ourselves to ask the hard questions as to whether we have properly functioning warnings for the presence of fog on the route and to what extent driver behaviour was at fault.
The speed limit is the maximum you are supposed to drive at if the conditions are perfect. It is not an entitlement.
