Yes Rich, I have heard the same thing.
Ever see the DOT at the toll booths doing random inspections of trucks? Toll tickets are always time stamped and they can write you up if they want - shut you down till you're legal as well.
A bit OT here but.....
As far as scale houses go, they don't keep track of time/distances between coops even if you use PrePass - at least thats what the PrePass contract states.
Scale house inspections are generally random - just luck of the draw, unless they notice some violation like a missing mud flap, light out etc. as you are passing through.
Specific carriers don't normally get tagged for inspection, an exception might be if the carrier miserably failed a recent DOT audit due to flagrant violations - and those results were published in every coop in the USA.
More often than not, scale house inspections won't even happen unless there are inspectors there that day or theres some seriously obvious violation that warrants the scale master closing the scales to do an inspection.
Now, when I was pulling freight for Swift, Swift had so many flagrant violations that the DOT gave them something like 2 months to get their act together - well, 2 months later they got re-audited, and again failed miserably.
As a result, Swift's saftey dept. put out the memo to all drivers about a dozen times to be prepared for frequent random and coop DOT inspections - but I never got pulled in, neither did any other Swift driver I spoke with after that.....I think it was just a scare tactic - and it didn't work because the next year's audit was even worse.
Fueling is one thing that needs to be watched though, the fuel receipts never have a time stamp but they do have the date.
If DOT wants, they can check your actual fueling time to compare with log book times, but they do not normally go that deep without a reason - unless maybe if you are involved in an accident.
Happy New Year!
