A few days ago I posted a snap shot from the DOT camera that covers the intersection and entrance to the MM126 truck stop and believe the truck seen circled in red is David's truck pulling up to the truck stop. The time stamp is dead on for when LE said David arrived there and the trailer is a livestock trailer like David was using. As you can see his lights are on, including his headlights and trailer lights. That doesn't mean that perhaps there was a loose wire that caused lights to turn on and off while driving.
So I got thinking. If David was having problems with his lights, and stopped at the MM126 truck stop to try and fix the problem, whats to say David didn't stop again at the exit to again examine the lighting problem. While stopped with perhaps the hood open, someone stopped and approached David.
Given the amount of time it took David to travel from the MM126 truck stop to the exit, suggest the average speed limit was just under 65 MPH. I think if the headlights were the problem David would have slowed down and the time it took him to drive that distance would have significantly increased. But maybe he fixed the headlights and they were working fine until just before he came up the exit and he then stopped to try and fix them again.
If the problem was with the trailer lights, it would not have affected his travel time, and at that time of night he would have likely just continued to Wiechmans and attempted to fix them there instead of stopping at the exit. If it was just one light on the trailer, which as you can see from the picture there are many, I think David would have had his mechanic fix the problems when he parked at the mechanics shop. One marker or tail light not working is not that big of deal and I don't think would be a reason for David to stop and try and fix out on the road.
