A semi trailer overturned along I-64 in Clark County early this morning. Officials say the driver of a UPS semi pulling tandem trailers was eastbound and about a half mile from the Montgomery County line when he fell asleep at the wheel. The semi went off the road and into a tree line. The rear trailer flipped. The driver was taken to a hospital, but officials say his injuries did no appear life threatening. Firefighters say the first trailer contained shot gun primer, but it would not pose a hazard unless the trailer caught fire.
