But like is it actually keeping anyone safe? If we disabled that noise across the board, would ppl actually die from being backed into by big trucks?

I'm all for worker safety, but I'd like to see evidence that this beeping is actually an effective measure vs a less annoying sound or the use of back-up cameras??

Seriously, where is the evidence of accidents avoided? Vs other measures?

side note: had to live next to a construction site for 2 years. The beeping started in the morning at sunrise and ran for 12 hours straight.

And I'm wondering what it is like for construction workers; for the noise to provide a safety measure, they would have to pay attention to it. But that means it can't be a constant. Which it is.
