These questions are directly from The FMCSA website (giving credit where due)
Question 1: A company told all of its drivers that it would no longer pay for driving from the last stop to home and that this time should not be shown on the time cards. Is it a violation of the FMCSRs to operate a CMV from the last stop to home and not show that time on the time cards?
Guidance: The FMCSRs do not address questions of pay. All the time spent operating a CMV for, or at the direction of, a motor carrier must be recorded as driving time.
Question 14: How must a CMV driver driving a non-CMV at the direction of a motor carrier record this time?
Guidance: If CMV drivers operate motor vehicles with GVWRs of 10,000 pounds or less at the direction of a motor carrier, the FHWA requires those drivers to maintain records of duty status and record such time operating as on-duty (not driving).
Ok by question 1 & 2 you must log if you are driving towards work (which is really what I thought). The only thing that relates to driving home is the personal use, so read that and take it how you want. Again for you non local drivers make sure the time bobtailing is resonable.
I am going to e-mail DOT today the 2 main specific questions I get all the time and get it in writting from them. I did ask the one officer and he feels the same as me the DOT book is very vague when stating within reasonable miles. The canadian book tells you 46.6 miles is acceptable any thing over that needs to be shown as driving.
To the original poster of this question I say you can log it as off duty going home, but going to work it should be logged as on-duty (that's the way I read it anyhow)
Grr not sure if I am posting this 2x's. Sorry mods if I did.
