Thanks to one trucker’s dashcam, we can see how another painfully avoidable wreck happened from start to finish.
In this video spotted by SpeedSociety, you can see how the trucker ahead tries to pull a u-turn at the narrow end of a weigh station. It is instantly clear to the trucker behind that the still-quite-sizable pickup truck and trailer are about to get clobbered.
And they do.
Once you put enough miles under your belt, I think you start to see a lot of this stuff coming.
