Don't know what kind of work they do, but they CAN'T read traffic signs!!! On 2/17, a pickup truck driver of theirs along with 2 other workers in the truck, made a left hand turn onto East. Brainerd Road from Gunbarrel (toward the Interstate) from the middle lane on Gunbarrel which is a straight only lane. If I had not been paying attention, there would have been an accident! There are lane signs there...read them!!!!!!!
