After watching too many dash cam videos where this happens, I’ve started using my hazards when I’m stopped at the tail of traffic on a fast road. I don’t know if it really helps but it could and at least it’s an attempt to be more visible

I had a coworker who was permanently and severely disabled in a situation like this.

He was stopped at a red light behind a few other cars. Someone not watching the road plowed into him at 40-45mph, pushing his car into the one in front of him. Brown back, broken teeth, don't remember what else other than that it was a lot. He was in the hospital for weeks.

Now I'm extra careful to leave some space between the car in front of me and mine when stopped, but even that can only help so much when you've got people driving around in heavy trucks like this.
