Makes perfect sense to me. Are most able to do that or would it depend on the company they work for or the particular load type?
I mostly haul meat or candy over the mountains, so that grants me leeway. An owner-operator or someone who lives in the area may feel a bit of pressure.
The truth is that I've been out here about eleven years now and I have never been faulted for an accident and so these companies need a few drivers like me to offset those that are real good runners, but burning up their license.
A speeding ticket and a few overweights are all that I have on my record(they may have been removed by now) - so I can go anywhere to work - and my company knows it - so they leave me to my own judgement.
