Safety rules for in-state trucks

North Carolina applies 49 CFR Parts 390-397 to for-hire and private intrastate carriers at 26,001 lb and up. It applies the annual-inspection sections of Part 396 to intrastate vehicles over 10,000 lb GVWR. (14B NCAC 07C .0101(b) and (d))

Intrastate hours of service: 12 hours of driving after 8 hours off, no driving after 16 hours on duty, and a 70-hour/7-day or 80-hour/8-day limit.
Annual (periodic) inspection rules apply to intrastate vehicles over 10,000 lb GVWR, a lower line than the rest of the intrastate safety rules.
Intrastate drivers can be exempted from the age (391.11(b)(1)) and some medical standards if approved by a DMV Exemption Review Officer.
The intrastate marking must end with the letters NC after the USDOT number.

The federal lines, which apply in North Carolina too

10,001 lb and interstate commerce: a USDOT number, a medical card, a driver qualification file, the hours-of-service rules and daily inspections (49 CFR 390.5).
26,001 lb: a CDL, for a single vehicle or a combination towing more than 10,000 lb (383.5). The CDL rules cover in-state driving as well (383.3), and drug and alcohol testing follows the CDL (382.103).
