Two children - aged three and five - managed to start a car and move it out of their drive, getting all the way to the nearest intersection before "T-boning" another car in Washington, USA.
"[It sounded] like and explosion went off – something, we really don't know. So I ran out and I saw it," the children's neighbour Annemarie Warren told KOMO News.
"I knew it was our neighbour's car, but I did not know she wasn't in the car. Only the two little ones.
"I held the kids both in their hands and I said, 'where's your mom?' They said, 'sleeping. I want to go to my grandma's house'. I was waiting for the mother to come out, too, you know?"
Police in Federal Way said the accident, which happened at around 11am on 6 September, had left the driver of the second vehicle bruised but that the children had escaped without any injuries.
In a post to its facebook page, the Federal Way Police Department said under a post entitled 'Did that happen?': "What happens when a 5-year-old and a 3-year-old want to go and visit grandma without telling anyone.....(see photos). Thank goodness no one was seriously injured when the children drove into an intersection and t-boned another vehicle."
It is not clear whether the children's parents will face charges following the accident.
