Only six out of ten young people in East Yorkshire would definitely try to persuade a drunk friend not to drive, according to a report.
New research compiled for driving school BSM, showed only 59 per cent of young drivers would definitely try to persuade a drunk friend not to drive.
Women were also far more likely than men to say they would definitely try to persuade a friend not to drive after drinking
Mark Peacock, head of BSM, said: "The majority of them do have a sensible attitude to keeping themselves and their friends safe and we need to encourage this to spread further in their peer group.
"Even if you are not driving, you can help keep safe by encouraging any friends who are driving not to drink and making sure you do not get into the car with a driver who is drunk or who has taken an illegal substance.
"No one wants to start the new year with points on their licence, a fine or worse still, an accident and injuries."
