You might be right. But, I believe the DOT reg's do not mention job classification. Road or city, when you show up for your given start time you are on duty not driving. If a mechanic @ you barn starts work @ 0700 drives the truck to the dealer & returns to the barn, his 14 hour clock started @ 0700. If he drives more than 100 air miles trying to recover a tractor, he has to log it. No exceptions. He has a CDL just like any one else hitting the street in a CMV. He has to log it on paper or electronically once he reaches the 100 mile air rule. ABF rules changed last year where you had to log all driving regardless of the distance if you drove. Any correction on my post is welcomed. von.
