Obama is coming for ya!
Beginning July 1, the Obama administration's Federal Motor Carrier Safety Administration (FMCSA) wants truckers limited to driving 70 hours a week with mandatory "restart" periods--which would "include the predawn hours of two consecutive days" for rest.
Currently, commercial drivers are allowed to drive 82 hours a week.
