Preface:
OK Mr Small Carrier,
Are you telling me the decision to replace that steer tire that's just fallen below minimums is not influenced at all by the fear that you just might have a blowout at a really inopportune moment that sends you out of control, crashing into a disabled car on the shoulder that's full of kids?
If you own and maintain your own equipment, many of us learn the financial lesson that taking care of that tire before it becomes a roadside repair issue is far cheaper in the long run than cheaping out on it in the first place.
For those that give Murphy the opportunity, he does take those opportunities presented to him to do his worst. That's where the safety part comes in. Yes, there's a financial aspect to it... its cheaper to not have to hire an attorney - if it goes in that direction.
Can you honestly say that you never have a moral twinge about what might happen to an innocent bystander if your negligence in the maintenance of your equipment leads to their death or serious injury? That's what the safety part is about. I don't know about you, but doing this better than the guy in the company truck is part of why I truck this way. It certainly isn't hard to stand out among owner ops. Hell, just replying to a broker's email, or sending them a daily location email makes those poor slobs deliriously happy. Thinking about how to run your operation safely pays off, because it turns out that your stuff isn't breaking down in the middle of nowhere most days.
Its pretty obvious that the big corporation bean counter really doesn't think about that sort of thing. As long as his quarterly balance sheet is in the black, his bonus is assured. Worrying about the carload of kids on the side of the road because of the tire request he just disapproved is someone else's problem, and there's always a schmuck in a truck who can be blamed.
