A hungry 6-year-old grabbed his grandmother's car keys, positioned his child seat behind the steering wheel and tried to drive himself to an Applebee's restaurant.

He didn't get far.

Unable to take the car out of reverse, the boy backed up 75 feet from her house into a transformer Tuesday, knocking out electricity and phone service to dozens of townhouses in this suburb north of Denver.

No one was injured and the boy, whose name was not released, got out of his car and told his grandmother what happened.

"He proceeded to start the car and started backing up," said Sgt. Colleen O'Connell of the Broomfield Police Department. "He went backward about 47 feet, hit the curb, then went backward another 29 feet."

Investigators couldn't figure out how the boy reached the accelerator.

No charges will be filed.

"I have five children of my own, so I know you cannot watch them every minute they're awake," said nearby resident Nancy Hollis, whose power was knocked out by the accident.
