More drivers are getting behind the wheel after drinking excessively the night before, a poll has shown.
A survey of 800 drivers and motorcyclists found that more than a third (38%) admitted to driving after drinking heavily the night before - compared with 28% who had said they do so in a similar poll seven years ago.
According to the study, almost half (45%) believe it would take two or more units of alcohol for their driving to be affected, while one in seven drivers think they would have needed three or more units.
Findings of the poll by road safety charity Brake and car insurance company Direct Line revealed that overall 35% admitted taking to the road after drinking any amount of alcohol at some stage during the last year - down from the figure of 51% in 2003.
Motorists convicted of drink-driving usually face a hefty increase in their car insurance premiums.
Julie Townsend, campaigns director at Brake, said: "Drink-driving remains a menace on our roads, devastating people's lives every day. A shocking proportion of drivers seem unaware of the dangers of driving the morning after a heavy night, or even small quantities of alcohol.
"We're appealing to everyone to stay safe over the festive season by planning ahead. Make sure you can get home safely, and stay off the booze if you're driving home or early the next day."
