Transport written question – answered at on 20 December 2010.
There are no sections of M5, M6, M1, M3 or M25 which are subject to lower statutory speed limits because they do not meet current visibility requirements or have sub-geometric features. There are, however, two locations on the M5 between junctions 1 and 4 where advisory speed limits of 50 mph are in place. One is on an elevated section between junctions 1 and 2 (Oldbury) and the other is at junction 4 (Lydiate Ash); both are due to the locations having a tight radius curve.
The M4 eastbound between junction 4 and just prior to the start of the elevated section just before junction 2 is subject to a permanent mandatory speed limit of 60 mph due to sub-geometric features.
The M4 eastbound just prior to the start of the elevated section at junction 2 to the end of the elevated section at junction 1 is subject to a permanent mandatory speed limit of 40 mph due to sub- geometric features.
The M4 westbound from junction 1 to the end of the elevated section just past junction 2 is subject to a permanent mandatory speed limit of 40 mph due to sub-geometric features.
The M4 junction 4 to junction 4a Heathrow Spur (both directions) is subject to a permanent mandatory speed limit of 50 mph due to sub-geometric features.
