§ Mr. Cohenasked the Secretary of State for Transport what reports his Department received (a) before the road was planned and (b) during its construction about the possibility of fog hazards on the M25 at points where the motorway crosses river beds.
§ Mrs. ChalkerSeparate studies were carried out before construction began on sections of the M25 crossing the Mole valley in Surrey, the Gade valley in Hertfordshire and the Colne valley in Buckinghamshire.
In August I announced that the Meteorological Office had carried out a study which identified places along the whole of the M25 which were particularly fog-prone. We are now considering what further steps we might take to help reduce fog-related accidents on the motorway. But there is only one real answer to the problem of safety in fog, and that is careful driving.
