Designated drivers are being urged to avoid taking an "inexcusable risk" and stay off the bottle during nights out this Christmas season.
Brake has revealed that attitudes towards drink driving have "dramatically changed" for the better in the last 10 years.
However, while most motorists apply the law uncompromisingly, a minority still feel drink driving is acceptable, Brake says.
The road safety charity has pointed out that by breaking promises to avoid alcohol, passengers - as well as the drivers and other road users - are being put at risk.
Julie Townsend, deputy chief executive of Brake, said: "Public attitudes towards drink driving have shifted dramatically, yet people are still being killed and injured by those who continue to take this inexcusable risk. We need action from government to rectify this and put a stop to the carnage that continues to result."
A survey of 1,000 UK motorists discovered that 68% will not get behind the wheel after consuming alcohol, while this figure stood at 49% a decade ago.
A third said they had driven after a small amount of alcohol, or while hungover the morning after, in the past 12 months, while over the same time 10% admitted driving after a heavy night in which they were certainly or potentially over the drink-drive limit.
