The AA has highlighted the dangers facing drivers travelling on unlit roads.
The motoring organisation says some councils turn out street lights in the early hours of the morning as an economy measure.
But Government figures show that over the past five years improved road safety has seen accidents in hours of darkness on built-up roads with street lighting fall 18.6 per cent overall, and 24 per cent in the wet, snow and ice. Yet, where street lights were off or not present, the reduction was 12 per cent overall and 16.7 per cent in bad weather.
The AA added that the situation was worse on faster roads, like the M65 in Lancashire where a campaign to light up a notorious dark stretch has begun following a series of serious accidents.
President Edmund King said: “New statistics show accident rates on blacked-out town and city roads are not getting better. In fact, on 40mph roads, they are getting much worse - particularly in bad weather.”
