At 7 a.m. Monday, troopers began checking cars that had been left beside the interstates in metro Atlanta.

As they did two weeks ago, yellow ribbon was used to mark cars that had been checked.

This time, however, they left notices that the cars and trucks would be towed if still there in eight hours.

By 2 p.m. Tuesday, troopers had checked 196 vehicles and towed 25 of them.
