...The semi was headed west when its raised bed slammed into the overhead sign near mile marker 200 as it approached the I-64/I-295 split.
Virginia State Police said the crash happened shortly after 9:30 a.m.
"The cab continued on and then stopped, obviously, because it had separated from the bed of the tractor-trailer," Matt Demlein, a spokesperson for Virginia State Police, said. "We're still investigating as to what led up to it actually hitting the sign. It was empty at the time."
Troopers do not know why the bed was raised or how long it was up before the crash. But officials said the truck had stopped at a weigh station about a mile earlier, which is equipped with cameras...
Maintenance would be on the driver since it's his responsibility to shut down the truck. U-Joint failures happen (on the tractor), but should be inspected daily (finger quotes).
Doesn't matter though, cause he left his bed up. There's no driveshaft on the trailer. If there were, it would take forever to hook a trailer lol.
