The Police Federation has issued a call for the drink-drive limit in England and Wales to be lowered to match that in Scotland, according to BBC News.
The Police Federation, which represents police officers in England and Wales, will issue the call at its annual conference in Bournemouth today (19 May).
It wants the limit reduced from 80 to 50 milligrams of alcohol per 100 millilitres of blood, and is also calling for more to be done to discourage women from drink driving.
The limit was lowered in Scotland in December 2014 and BBC News says prosecutions for drink driving have fallen by a third since then.
The Police Federation says that while more men than women are still caught drink driving, convictions among women are increasing as a proportion of all cases. A session at its conference will look at ways to tackle the problem of women and drink driving.
A report published last September highlighted the issue of women and drink driving, and called for and for road safety messages to make it clear that drink driving is not a just a male problem.
Victoria Martin, Police Federation spokesperson, told BBC News: "We’ve seen a steep decline in men drink driving over the years, with targeted advertising campaigns which is great, but women don’t seem to be getting the same message."
The call for a lower drink drive limit has been supported by GEM Motoring Assist.
David Williams, GEM chief executive, said: “Scotland reduced the limit at the end of 2014 and Northern Ireland is considering a similar plan. This would leave England and Wales alone with the highest drink-drive limit in Europe.
"We support the Police Federation in urging the Government to make this a priority task on its road safety agenda."
