Because once they are on the road, it's pretty much a go to the other side type thing. There's not really any places for the trucks to turn around on the road at all. It's better for the cop to ride out in front of the truck and have people get out of the way.

The cops are there for the speeders, the trucks are a secondary issue.

It absolutely blows my mind that semis drive on 129 through there. I was staying at DGMR up in the woods to where I could kind of see the road through the trees at camp. Late at night I saw a couple of semis going west and I thought for sure they were lost and were going to get trapped. Crazy shit.

This is what it looks like to see your friend almost get killed by a semi

Normally, I"m not for any laws because some clown did something stupid, but watching that video makes it clear that the road is simply too sharp for semi-trailors.
