As many as 21% of people plan to drink at least 10 units of alcohol at New Year's Eve celebrations, potentially putting them still over the limit by 12 noon on New Year's Day.
And the the AA/Populus survey of more than 21,000 drivers also revealed that 2% would drink to such an extent that they risked being over the limit as late as 10pm on New Year's Day.
Of drivers aged 18-34, as many as 13% said they would knock back enough to still put them over the limit by 6pm on January 1, while drivers in Northern Ireland were most likely to say they would not be drinking at all.
Drivers in London and the North East of England were most likely to drink the most on New Year's Eve.
A separate AA/Populus survey earlier this year showed that 56% of drivers did not know when it was safe to get behind the wheel the morning after drinking.
Also, police figures showed that in 2011 more people failed breath tests between the hours of 6am and 11am than during the hour before or after midnight.
"The best advice we can give is to avoid excessive drinking if you know you need to drive the following day."
