Responding to reports that suggest the Transport Secretary may consider a review of speed limits on UK motorways, RAC head of policy Nicholas Lyes said:
“The Transport Secretary raises a valid point in relation to the possibility that overall emissions could be lower if a move to an 80mph limit was accompanied by a large increase in the numbers of electric vehicles using these roads.
"However, any move to raise speed limits on motorways to 80mph is fundamentally an issue of safety. Part of the problem is that at present, there is a high proportion of drivers that break the 70mph limit, and drive nearer to 80mph. If the speed limit were to be changed to 80mph, there is a risk that the new default becomes even higher.
"Our motorways are currently the safest roads on the entire network, and we wouldn’t want to see anything happen that changes this. So unless there is compelling evidence that a change in the limit on some stretches of road would not adversely affect safety, the current limit should be retained.”
