Ice on trailer roof blows off and hits our car

Not trivial when you are in a car, (not high up in tractor cab), in stop & go traffic and the lights cause dots in your vision. (What's that called? At 02:53 can't think of the term.)

Co-driver and I are doers, not complainers, but this is ridiculous - as though we wouldn't see steady amber lights?

 

This is "Questions to Truckers from the General Public"

You can't allow ice from blowing up and off your trailer and damaging vehicles in other lanes.
If it hits a vehicle in your lane, the driver was following too closely.
Hit my vehicle as he passed me in lane 2 and I was in lane 3.

I never allowed stuff to fall from the dump truck I drove. Meaning I climbed onto the load and anything which could be a problem I shoveled below the rim.

 

It's OK. I can take it.
Speak your peace.
Just don't allow big pieces of ice to damage others' vehicles or worse.

Or is this about blinding oversize lights. Yes, ridiculous.
Wait until someone claims they were a little blinded and disoriented by the lights and collides with another vehicle.
Attorneys will go after the driver, his company, trailer manufacturer, LED light manufacturer, the owner of what is being transported, etc.
