A 5-year-old boy with $3 in his pocket was pulled over by Utah police while driving his parent's car to California to buy a Lamborghini.
The boy left in the SUV after arguing with his mother, who said she would not buy the luxury car for him, Utah Highway Patrol said on Twitter.
A trooper spotted the vehicle weaving on Interstate 15 at 30 mph, the Utah Highway Patrol said.
Troopers told CNN affiliate KSL-TV they initially thought the boy was an impaired driver.
"How old are you? You're 5 years old?" Trooper Rick Morgan says in dash camera footage of the traffic stop. "Wow ... Where did you learn to drive a car?"
Morgan told KSL-TV he had to help the child get the SUV into park.
"He was sitting on the front edge of the seat so that he could reach the brake pedal to keep the car stopped while I was standing there," he said.
