A 5-year-old boy hopped behind the wheel of a sport utility vehicle and drove it several blocks looking for his mother following an argument with his grandmother, authorities said.
The child was not injured in his short drive last Wednesday, and his grandmother's 2004 Cadillac Escalade was stopped without incident.
The boy, whose full name wasn't released, started the truck, cranked up the stereo and stood on the driver's seat to see over the steering wheel, Washtenaw County Sheriff's Cmdr. Dave Egeler told The Ann Arbor News.
The boy told sheriff's deputies he was "looking for his mommy," police reports said. He was not expected to face any charges.
A motorist called police to report that her vehicle was nearly struck by an SUV that appeared to be driven by a child. Egeler said an off-duty deputy also noticed the boy and pulled him from the vehicle before he drove any farther.
The boy and his grandmother, who is his custodial guardian, got into an argument at their home in Ypsilanti Township, Egeler said. He grabbed the car keys and was told to drop them, authorities said but took off after the grandmother became distracted by her infant granddaughter.
Ypsilanti Township is about 30 miles west of Detroit.
