Trucks need to have semi levels of regulations for headlights

I see plenty of trucks with headlights well above semi trucks, and I've yet to be blinded by any semi headlights, even the stupid white blue colored ones due to their regulations of height and angle actually being enforced

Mirror doesn't work, hang emergency visibility jacket over your seats. Sometimes those do when they reflect back and catch their eye, and they won't net you a ticket

In older cars, where you could manually flip the rear view mirror to dim it, my dad would flip it back and forth trying to flash the person behind him so they’d get the hint about their high beams. Not sure it ever worked…

That's probably legal, I say go for it. Get the largest retroreflector you can find. I think they make reflective tape that should do the trick.
