The Government has been accused of sending "mixed messages" to motorists after a plan to put the brakes on young drink-drivers was scrapped by ministers.
Westminster's official drug policy advisers, the Advisory Council on the Misuse of Drugs (ACMD), said the legal limit for drivers under 25 should be slashed by more than a third.
This would have put some drivers over the limit after just one pint.
But ministers threw out the idea yesterday.
Today, drink-driving campaigners in Bradford said half-measures weren't enough and merely confused people.
Carole Whittingham, manager of Brighouse-based national Campaign Against Drinking and Driving, said: "I've never heard such a silly proposal in my life and it would be totally impossible to implement."
She added: "It would have been more encouraging if they had lowered it for everyone or introduced a zero ban.
"At the moment people don't even know the correct measurements of what they can drink.
"The Government are giving a very mixed message, on the one hand the Government are extending licensing hours, on the other they are proposing these bans."
ACMD's report said the legal limit may need to be reduced to 50 milligrams of alcohol in 100 millilitres of blood for motorists aged 17 to 25, but stay at 80mg for adults.
It also called for much stricter controls on the sale of alcohol and tobacco, saying the laws were rarely enforced.
The ACMD committee told ministers to consider raising excise duty on alcohol to combat Britain's growing binge-drinking culture and general alcohol abuse.
Philip Gwynne, head of public affairs at West Yorkshire Casualty Reduction Partnership, acknowledged the report and said: "This is another organisation, with another proposal which is concerned with keeping people on the streets safe.
"Their intention is the same as ours, keeping people safe."
A spokesman from ACMD said: "Drivers under the age of 25 are more likely than older drivers both to have road accidents and to fail alcohol tests when involved in accidents."
The 100-page report also called for a ban on alcohol advertising on TV and at most cinemas.
The ACMD said the alcohol industry spends about £200 million annually on promoting a misleading picture of the realities of alcohol consumption.
Transport minister Stephen Ladyman said: "The Government has no plans to change the drink-drive blood alcohol limit from 80mg for young drivers or for anyone else.
"We will continue to work with the police and others to drive home the message that drinking and driving kills."

WHAT YOU SAID
June Bentley, 48, of Bransdale Clough, Bradford: "I don't think people should be able to drink and drive at all."
Hamid Butt, 32, of Shay Close, Bradford: "There should be a blanket ban on drinking and driving. If you were safe when you drink and drive then why don't bus drivers and taxi drivers do it?"
Keith Boyce, 74, of Bryanstone Road, Bradford: "People are ignorant, they kill themselves and other people and the Government encourage drinking by extending licensing laws."
Caroline Kaye, 55, of Stone Croft, Bradford: "A lot of other countries have a zero limit on drinking and driving. If other countries can manage it, then why can't we?"
Freda Hussain, 29, of Piccadilly, Bradford: "It's not right to drink and drive. If people want to go out and have a good time, they should make alternative travel arrangements."
