My company has them, but they don’t monitor them, they’re only for accident review. How do I know this? I put a sock over mine for two months and never heard a peep from Safety.
You took the sock off when you caught yourself having conversations with it, and the sock made good sense, right?
I don't know if this extends to tires but I was at a TA earlier today getting a mud flap and they were talking about having trouble getting their trailer tires in. Didn't catch much of the conversation other than that so it might have been store specific.
