In Michigan, all commercial vehicle plates expire February 28. For some companies, this can run tens of thousands of dollars, but even for smaller ones, this is a big expense. Fleets (ten or more renewals) drop their work off, and we call them when they are ready. A clerk just came to see me. She had finished a fleet of 30 trucks, and found that the check to pay for it all was unsigned. She called the office, and was told that the owner (after dropping off his work here) had left for vacation and will not be back until March 11. I told her to call back and tell them that we would not be able to process anything without payment, and an unsigned check would not cut it. We would void out all our work, and we could process it on March 11, and oh, yes, of course, late fees of $10 each would also be due. Gee, they managed to catch him before he got too far north, and he was able to come back and sign the check.
