IF you are Non-Exempt then all time from when you pick up the company vehicle at the office to when you return the company vehicle to the office except for a bona fide lunch break would be time worked. The related rules are in the 29 CFR 785.33 (http://www.dol.gov/dol/allcfr/ESA/Title_29/Part_785/29CFR785.33.htm) - 29 CFR 785.41.

IF you are instead Exempt Salary, then you never have a right to paid more then your salary.
