Metrication of speed limits is in principle desirable for consistency with road distance signs and with general national and EU policies in favour of metrication. Such a change will, however, have to be managed so as not to compromise road safety or the important targets in this regard set by the Government Strategy on Road Safety 1998-2002.
A working group of relevant agencies, chaired by my Department, is to recommend on the implementation of metricated speed limits. It is not likely to be practicable to complete the implementation process by mid-2001 and a revised target will be established shortly based on the assessment of the above working group.
