Well, it looks like someone forgot to lower the truck bed. This truck driver was caught crashing into an overhead sign. Yes, he sure destroyed it completely. He was just travelling down this highway in Saudi Arabia with his container up like nothing is happening.
He didn’t notice he had left the bed raised up until it was too late because he was probably in a hurry. On the footage, we can see a pickup truck speeding up behind the truck driver, probably to warn him but, he fails to make it so, the raised container takes down the sign. Luckily, nobody got hurt and nobody was hit with the falling debris of the demolished sign.
