The majority (80%) of motorists say those who repeatedly drink drive should have their vehicles seized and sold or scrapped, according to a poll by the IAM (Institute of Advanced Motorists).

Half think that this should also happen to drivers several times over the limit.

Two-thirds (66%) of the respondents were also in favour of reducing the drink-drive limit, with most of these saying it should be lowered to a maximum of 50mg of alcohol per 100ml of blood.

More than a quarter (28%) think we should have a zero-tolerance policy.

People convicted of drink driving generally lose their licence for a year and receive an average fine of £240. But 57% think this is too weak, and that punishments for drink drivers should be tougher – 38% say much tougher.

Other findings include:

• 55% of poll respondents support a proportionate, graduated system of penalties, if the limit was reduced. For example, lower penalties would be given to drivers caught under the current limit, but above the new one.
• Almost half of respondents admit to having a drink while driving, within the current limit.
• 79% say a decrease in the limit wouldn't affect their enjoyment of an evening out. 19% said it would.
• 84% said a reduction in the limit wouldn't change their plans to go out.

Simon Best, chief executive at IAM, said: "The support is there for tougher treatment of drink drivers.

"Not only do the majority want a lower limit - they also want tougher punishment for those that break the law, especially the worst offenders who present the greatest danger to other road users, their passengers and themselves.

"Our poll shows a desire to see more effective drink drive levels as well as much greater consistency of enforcement, prosecution, and sentencing, which reflects the level of danger associated with drinking drivers."
