Motorists on a section of U.S. 1 in Stafford County found the going a bit rocky, thanks to a prank.
Sheriff's spokesman Bill Kennedy told The Free Lance-Star that someone put 20 large rocks across the northbound lanes in the area of Coal Landing Road early Wednesday morning.
One vehicle got a flat tire after it hit the rocks. Another vehicle that hit the rocks didn't appear to have sustained any damage.
The rocks weigh 5 to 8 pounds each. Police believe they were removed from a nearby ditch.
Kennedy said it's fortunate that there wasn't more serious damage or a serious injury.
