A woman whose father was reportedly killed by a drink driver is determined to prevent others from suffering similar tragedies.
She held a sign which read: "Hi, my name is Angela. If you have been drinking tonight, I'd like to offer you a free ride home.
"Two years ago this week, a man was drinking and driving and killed my father. In honour of his memory, I'd like to help keep the roads safe tonight."
Pictures of Angela's good deed were uploaded to Imgur under the username bcisaidiwould.
The account is thought to belong to one of her friends, who drove the car while she spoke to passengers they picked up from the street.
Unsurprisingly, Angela and her sign got a lot of attention from passers by.
And several people took her up on the offer of a free lift.
One woman was so overwhelmed by Angela's story that she gave her a hug.
