One easy such thing, is puttling a piece of metal over a tractor trailer’s wheel area, so you get deflected if you go under and not chewn up and spit out. It’s voluntary and few trucks have it on them yet but a bunch of little stuff like that could help.

I thought those were for airflow. They do not look strong enough to deflect anything bigger than a bicycle.

I just saw one of these blockers the other day, almost all trucks do not have them though. I’m not sure what you are referring to exactly.
