I could see that happening near me. I saw an ad on CL for a Fed Ex ground route. Ad said it would take at least 10 hours to complete the route. Started in LaCrosse, Wi, route was 250-300 miles. I have seen the same type of ads in SD, ND and western Mn. I know there is a 300 miler that dispatches out of the center in my home city.
I was picking up at a warehouse while the ground guy was also picking up. He asked me how often I broke the daily or weekly hours of service. I told him 'never.' He said he was routinely on the clock from 6a to 9 or 10p. I said there was no way any franchise owner would allow that. He said that the owner had just bought the routes and asked him to do a favor by working the extra hours. Young and stupid. Poor guy.
While we were talking, the Spee Dee guy shows up and he says that they routinely break the hours of service rule (the owner of Spee Dee is cheap, but I am pretty sure he does not break the HOS laws) anyways, a neighbor of mine is a State Patrol commercial inspection officer. I relayed those stories to him and while he agreed that the Spee Dee guy was probably full of it, he wondered about the Ground guy. He said he would look into it.
Turned out, Spee Dee freaked out by the audit and they did have some violations. Never heard about the Fed Ex guy, so do not know if anything happened.
A few years before that, I told the same commercial enforcement guy about the DHL feeder guy that was swapping trailers at another place. Half the tires on the empty he pulled in and half on the loaded trailer were bald. The Hwy patrol put both trailers out of service and 4 skids of premiums missed service.
Would I turn in these guys if I did not know an enforcement guy??? More than likely not, it was very, very easy, so why not?
