A total of 7% would drive way away if they accidentally scraped an empty parked car in a quiet side road, the poll by breakdown service Autonational Rescue found.
A further 7% said they would make an effort to find the vehicle’s owner but if they could not do so, would just leave.
Almost a quarter of drivers up to the age of 24 would not own up if they scraped a parked car, compared with 5% of those aged 55-64.
Overall, 84% of the 1,013 adults surveyed said they would own up to the damage they caused by either leaving a note or waiting for the car’s owner.
In addition, 13% would report the incident to the police, with more men (14%) than women (11%) prepared to do this.
Autonational’s Ronan Hart said: “The need to contact police obviously depends on the seriousness of the accident. However it is reassuring to know that such a large proportion of drivers would still own up their mistakes.
“Leaving a note with contact details is always the best way to deal with any incident, no matter how small.”
