I was wondering when a for-hire freight hauler running interstate has to run in accordance with HOS and logbooks. I understand a cargo van doesn't require it unless hauling hazmat, and some carriers may require a maximum mileage per day. Aside form that is a logbook required for vehicles of a certain weight, say over 10,000# gvwr. Or can a vehicle under 26,000# run without logs or HOS since they don't require a CDL (unless Hazmat) Been online at FMCSA, but have trouble navigating site.
