Google Maps
this is a view of the intersection that Jason is said to have taken a left turn at and eventually ended up on Salt Flat Road instead of a right turn on 183 to take him to Route 10 and home.
Is that a camera that is pointed the direction he is coming from? Also, the signs are pretty clear as to his making a right hand turn to take him to Route 10, particularly since he had done it before. I also did this Google street trip all the way down from TSU and noted that every large intersection had what looked like these cameras on them. (They may not be cameras) and I also noted only a Texaco station on the right on the way down. All this for discussion.
You can click and drag so to see what it looked like when he made the left hand turn.
