...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...
Probably one complication is that the trucks need to be able to drive while the bed is up in normal operation. They have to move forward while dumping to spread the load.
At speed?
Therein lies the complication.
Nah, all trucks transmit their speed on the CAN network. It's very simple to implement.
Sounds like you found your million dollar idea! Now its as easy as cashing all your cheques! Congratulations!
