More than 70% of motorists would support a lowering of the legal drink-drive limit, according to a new survey.

And 92% would like to see a new anti drug-drive law introduced, the poll by road safety charity Brake and insurance company Direct Line found.

As many as 71% of the 800 drivers polled agreed the current drink-drive limit of 80mg of alcohol per 100ml of blood should be cut.

More than half (55%) said the limit should be 20mg or lower, while 16% favoured a 50mg limit which is the figure in operation in a number of EU countries.

The poll also found 92% would like to see a drug-drive law similar to that used for drink-driving.

The results come ahead of a soon-to-be-published, Whitehall-commissioned report on drink-diving and drug-driving.

Brake deputy chief executive Cathy Keeler said: "It's time for bold action by policymakers to demonstrate they are listening to public concerns on drink and drug-driving."

She went on: "Our drink-drive limit and drug-drive laws are hopelessly out-of-touch with public opinion and the weight of evidence showing just how dangerous it is to mix drink or drugs - or both - with driving.

"We desperately need a solid legal foundation for the clear messages of the Government's THINK! road safety campaign: don't drink any amount of alcohol and drive; don't take any impairing drugs (whether legal or illegal) and drive. The message is: Not a Drop, Not a Drag."
