A new nationwide strategy to cut speed limits on main A-roads to 50mph across the UK may help keep down rates for cheap car insurance.
And related proposals to reduce limits to 20mph near schools and on residential roads also could help motor cover customers enjoy better deals by cutting numbers of accidents.
Road deaths are now averaging eight per day on British roads, although the government is on course to cut accidents resulting in death or serious injury by 40 per cent next year.
The new measures are forecast to save 1000 lives a year from the current 3000 annual deaths, many of them young drivers and their passengers.
Imposing 20mph limits has been proved to save lives, according to the government, with road safety research showing that one in five people are killed when hit at 30mph. The survival rate increases at 20mph when 39 out of 40 people live after being hit.
While the plans to reduce speed limits could help cut accidents and reduce cheap car insurance rates, motoring organisations are sceptical; both the AA and RAC say the restrictions might prove ineffective.
