We have a guy at work that has 1 million safe miles in the past 14 years. He has the company jacket to prove it. And he is a city driver that never leaves our state.
We have road drivers that get over 3200 miles in a 5 day week. At 47 weeks a year they can get 2.5 million in 15 years but few if any at all run that hard for that many years.
I have over 3 million and worked as a equiptment operator for several years.
