§ Mr. Wingfield Digbyasked the Minister of Transport whether he is satisfied that double white lines are reducing accidents to any substantial degree; whether he is aware of the high cost of maintaining them; and if he will make a statement.
§ Mr. MarplesStatistical evidence so far does not indicate that double white lines have resulted in a significant change in accidents. However, the consensus of opinion among police, county surveyors and divisional road engineers who have reported on them is that they have led drivers to take greater care and that they justify retention. They are still under systematic observation.
§ Mr. Wingfield Digbyasked the Minister of Transport whether he will make regulations to prevent vehicles from loitering on roads where there are double white lines.
§ Mr. MarplesNo. Apart from the difficulty of enforcement, I am loth to introduce regulations which might encourage people to drive at a speed greater 191W than they consider safe at places, such as those marked with double white lines, where caution is particularly important.
