What happened? This crash closed Interstate 64 in Henrico County for hours

A dramatic image captured from a VDOT camera showed the crashed tractor-trailer appearing to be leaning on an overhead highway sign.

…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…

    Not just that, but you need a standard to communicate it truck to trailer and retrofit it so it all plays nice.

    Could be done on a dump truck though if there is a way to set a separate governor in the computer that gets enabled by the bed up light somehow.

          Usually you can access it through the obd2 port.

          But realistically, there’s no reason why you can’t design the hydraulics in a way that the cylinder is always leaking through an orifice and the dump trailer is constantly slowly lowering itself unless you are actively holding the Up button. There’s never a case where a truck needs to hold it’s dump up in the air for long periods of time.

            That is a hilarious and practical suggestion. It would confuse and irritate so many people, even though it’s no issue like you say.
