Residents in the boy's subdivision have lodged numerous complaints about motorists driving as fast as 55 mph on the 25 mph road. But Landon Wilburn, 11, took matters into his own hands, The Courier-Journal newspaper in Louisville, Ky., reported Thursday.

Neighbors said the boy can often be seen at the roadside holding his Hot Wheels toy radar gun -- which actually measures the speeds of the cars -- while wearing an orange vest and flashing a battery-operated flashlight with a built-in siren, the newspaper said.

George Ayers, 61, a resident of the neighborhood, said he at first didn't recognize the young roadside vigilante. He said that at first glance, the 11-year-old appeared to be a police officer.

"When I saw it happening, I got the biggest kick out of it," Ayers told The Courier-Journal. "People were locking up their brakes when they saw him."
