There's a reason they have laws and regulations dealing with just about every bit of equipment we use. The same reason that the scales will stop you if you pull in over-weight. Because you're over-weight doesn't mean the wheels are going to fall off. But there is a reason for weight limits.
Surely you've dealt with overzealous police before? That aside, the driver asked the scalemaster to approve the landing gear. Do you really think that guy is going to give a pass to a piece of broken equipment--a DOT violation--down the highway? If he says, "Go ahead," and it breaks down the road, then the scalemaster is also potentially liable. Think there is even a remote chance that he is going to put his ass in the sling? Better to stop the trailer at the scales and have it potentially break there then past his post.
The bottom line is we are paid check off our equipment BEFORE we leave. That is the driver's responsibility. If the equipment doesn't pass the driver's check, the equipment needs to be made whole, or it doesn't leave the yard. And if an current inspection sticker is required by law, then it better be on the equipment. No mechanic or member of management can say otherwise. It's not their ass on the line. It's yours.
