This isn’t Sucky AV, but rather Sucky Electronics. Deal with it.
In the first photo, near the bottom, you can see the deceased’s brother, who was paying respects.
There’s an overpass in Georgia that eats trucks.
The support is very close to the right lane, and there’s a lip of asphalt on the pavement. If a truck’s right wheels get on the outside of this lip, it will tip the box enough to collide with the support.
Apparently the wrecker said this was the second truck that day, and the 11th of the year, and it was only April.
Hat tip to MM, MD, JW and KL.
