§ Mr. Ioan Evansasked the Secretary of State for the Environment if he has now completed his review into the existing level of road lighting; and whether he proposes that any reductions should be made.
§ Mr. Mulley:The lighting of motorways and other trunk roads is confined to those lengths where the saving of accidents considerably outweighs the energy costs. Street lighting is additionally justified by the safety of the public and the prevention of crime.
Opportunities for saving energy in this area of activity are not likely to be great, but small economies may be available without prejudice to safety from changes of standard, or in lighting practice. I have called for a study of any such possibilities but I cannot anticipate its results, as this will require detailed and careful examination.
