For someone to be hit by or collide with the side of the truck, the truck has to turn in front of them.
If the truck turns behind them, they get hit by the front of the truck. But people and objects in front are also most visible to the driver.
It's why a lot of trucks have warning signs on the back. This truck makes wide right turns. In this accident it is important to note that a witness described the rider as "trying to push off of the truck. That suggests near parallel movement. There is no way I get taken out by a big rig there with the circumstances as they were described. Keep your head on a swivel my friends.
