One in four people in Northern Ireland say they would drive after drinking alcohol, a new survey has found.
The annual Road Safety Monitor Survey also found half of passengers would get into a car where the driver had one drink.
Environment Minister Mark H Durkan said he was concerned at the findings.
"I am concerned that a quarter of drivers would get behind the wheel of a car after one alcoholic drink," he said.
"My message to all drivers is clear, just one drink will impair your driving ability.
"Drinking alcohol and choosing to drive can have tragic consequences and I would urge everyone to play their part in persuading drivers to never, ever drink and drive."
The study also found that the majority of the public would support randomly breathalysing motorists.
Some 83% of people said they would support the police stopping people to check if they were driving under the influence of alcohol.
