Several years ago, after working a midnight shift and then some OT, I was driving home ... Actually, I was within 1/8th of a mile of my driveway and fell asleep. I crossed over the other lane, went off the road and down into a ditch. As I was going into the ditch I woke up and saw the backside of a "Stop Ahead" sign that was mounted on a 4x4 post dead ahead. I hit the sign and clipped it off. The sign and post flipped up over my car and landed behind me. Meanwhile, I hit the gas, drove out of the ditch, on to the road and then just turned right into my driveway. No injuries or vehicle damage.
