Schedules to conform with speed limits.
49 C.F.R. § 392.6 mandates that:
"[n]o motor carrier shall schedule a run nor permit nor require the operation of any commercial motor vehicle between points in such period of time as would necessitate the commercial vehicle being operated at speeds greater than those prescribed by the jurisdictions in or through which the commercial motor vehicle is being operated."
The official regulatory guidance states daily driving distances that are questionable or presumed excessive in areas with speed limits of 55 mph and 65 mph.
