For intrastate carriers, North Carolina applies 49 CFR Parts 390 to 397 to vehicles of 26,001 pounds or more, vehicles designed or used for 16 or more passengers, and placardable hazmat vehicles (14B NCAC 07C .0101). Intrastate drivers may drive up to 12 hours following 8 consecutive hours off duty and may not drive after 16 hours on duty following 8 consecutive hours off duty, with 70-hour/7-day and 80-hour/8-day limits. The big exception: the federal annual (periodic) inspection rules apply to North Carolina intrastate vehicles over 10,000 pounds GVWR. Intrastate trucks over 26,000 pounds display the owner's name and a USDOT number followed by "NC". Interstate carriers follow federal rules exactly as in any other state.
Who this guide is for
This guide is for North Carolina owner-operators, local and regional fleets, and safety managers sorting out which trucks fall under which rules. North Carolina is home to 22,737 interstate carriers in FMCSA's census (ninth of 51), 88.0% of them running 10 or fewer power units, and the state reported 215,661 roadside inspections in the most recent 24-month window, more than larger states such as Florida, Pennsylvania or Illinois.

North Carolina intrastate rules vs federal rules
| Topic | Federal (interstate) | North Carolina intrastate |
|---|---|---|
| Weight where Parts 390-397 start | 10,001 lb | 26,001 lb (or 16+ passengers, or placardable hazmat) |
| Annual (periodic) inspection, 49 CFR 396.17-396.23 | 10,001 lb | Over 10,000 lb GVWR, for-hire and private |
| Driving limit / window | 11 hours / 14-hour window | 12 hours / no driving after 16 hours on duty |
| Weekly limit | 60/7 or 70/8 | 70 hours in 7 days or 80 hours in 8 days |
| Minimum driver age | 21 | Federal age rule (391.11(b)(1)) does not apply to otherwise qualified intrastate drivers |
| Medical standards | 49 CFR 391.41 | Waivers possible through an Exemption Review Officer, for up to two years |
| Marking | USDOT number | Intrastate trucks over 26,000 lb: owner's name and USDOT number followed by "NC" |
The annual inspection exception carriers miss
The annual inspection exception is the one carriers miss. A 15,000-pound intrastate box truck sits below North Carolina's general 26,001-pound line, so its driver may not need a federal-style DQ file under the state rule, but the truck still needs a documented annual inspection under 49 CFR 396.17. Vehicles that are subject to the federal Part 396 inspection are, in turn, not subject to North Carolina's annual state safety inspection (G.S. 20-183.2). Our guide to annual inspection records covers what to keep, and who can perform the inspection.
North Carolina defines its planting and harvesting season as January 1 through December 31 for the federal agricultural hours-of-service exemption (G.S. 20-381(c)), and covered farm vehicles in intrastate commerce are exempt from federal marking rules. Older guides cite the rule as 19A NCAC 03D .0801; it moved to 14A NCAC 09J .0101 in 2009 and to 14B NCAC 07C .0101 in 2013, and was readopted in 2018.
Who enforces trucking safety in North Carolina
North Carolina law gives the State Highway Patrol authority to enforce the state's motor carrier safety article, the rules adopted under it, and the federal safety and hazardous materials regulations (G.S. 20-381). The Patrol may also determine the safety fitness of intrastate carriers, assign safety ratings under 49 CFR 385.3, and order carriers out of service. Intrastate transportation of passengers or household goods additionally requires a certificate from the North Carolina Utilities Commission (G.S. 62-262).
What North Carolina roadside inspections find
North Carolina's inspection data is equipment- and paperwork-focused in a specific way: tires are the most frequent violation group, followed by lighting, inspection reports and high-severity license-related violations. Out-of-service rates at North Carolina inspections are below national averages (4.0% of driver inspections and 19.0% of vehicle inspections, against 6.2% and 22.5% nationally), and hours-of-service violations appear on only 2.9% of driver inspections. North Carolina records a very high volume of inspections, which tends to include many quick checks of compliant trucks.
| Roadside inspections, September 25, 2024 to September 24, 2026 | North Carolina | 50 states and DC |
|---|---|---|
| Inspections reported by the state (all carriers) | 215,661 | 5,653,653 |

| Vehicle out-of-service rate | 19.0% | 22.5% |
| Driver inspections with at least one HOS violation | 2.9% | 7.8% |
| Vehicle inspections with at least one maintenance violation | 27.6% | 48.9% |
| Most frequent violation groups at North Carolina inspections | Violations | Share of all violations recorded |
|---|---|---|
| Tires | 12,174 | 16.5% |
| Lighting | 11,344 | 15.4% |
| Inspection report violations (FMCSA: Inspection Reports) | 5,367 | 7.3% |

Source: Fleet Regulators analysis of FMCSA Safety Measurement System (SMS) input files, monthly run published October 2026, covering roadside inspections recorded September 25, 2024 to September 24, 2026. "In the state" means the inspection was reported by North Carolina, whatever the carrier's home state. Driver rates use Level 1, 2, 3 and 6 inspections; vehicle rates use Level 1, 2, 5 and 6. Group names are FMCSA's. Same method as our HOS roadside violations study.
North Carolina-based interstate carriers, wherever inspected, had a driver out-of-service rate of 5.8% and a vehicle out-of-service rate of 21.0%. These figures describe what inspectors recorded, not how safe carriers in the state are. Rates move with enforcement priorities, which inspection levels a state favors, where it inspects, and which carriers pass through.
Practical reading: tread depth, inflation and sidewall condition, plus working lamps, account for nearly a third of what North Carolina inspectors write up. Those are pre-trip items. "Inspection reports" violations usually mean missing or incomplete driver vehicle inspection reports, which a daily habit fixes. See our Vehicle Maintenance BASIC guide.
Where North Carolina carriers get caught out
- Skipping annual inspections on 10,001 to 26,000 lb intrastate trucks. The periodic inspection rule reaches below the general threshold.
- Using intrastate hours on interstate loads. The 12/16 limits apply only to intrastate driving.
- Markings. Intrastate trucks over 26,000 pounds need the owner's name and USDOT number with "NC", unless an exception applies.
- Tires and lamps. The most frequent findings in the state's inspection data.
- Outdated citations. Policies that still cite 19A NCAC 03D .0801 were written against a superseded rule.
North Carolina compliance checklist
- Sort vehicles into three groups: over 10,000 lb (annual inspection), 26,001 lb and up (full intrastate rules), interstate (federal rules).
- Keep annual inspection records for every vehicle over 10,000 lb GVWR.
- Mark intrastate trucks over 26,000 lb with the owner's name and USDOT number plus "NC".
- Apply 12/16-hour intrastate limits, after 8 consecutive hours off duty, only to intrastate trips.
- Keep driver qualification files (see the DQ file checklist), including any medical waiver and its expiration.
- Run daily tire and lighting checks; complete DVIRs every day.
- If you haul passengers or household goods intrastate, hold the Utilities Commission certificate.

For most of 49 CFR Parts 390 to 397, 26,001 pounds, or vehicles designed or used for 16 or more passengers, or placardable hazmat vehicles. The federal annual inspection rules apply to intrastate vehicles over 10,000 pounds GVWR.
Up to 12 hours, with no driving after 16 hours on duty, and 70-hour/7-day or 80-hour/8-day limits, under 14B NCAC 07C .0101. Interstate driving stays under the federal 11-hour and 14-hour limits.
Intrastate trucks with a GVWR over 26,000 pounds must display the owner's name and a USDOT number followed by NC, unless they are subject to 49 CFR Part 390, are a type listed in 390.3(f), or are licensed at the farmer rate (G.S. 20-101).
Vehicles subject to the federal Part 396 inspection are not subject to North Carolina's annual state safety inspection under G.S. 20-183.2. Emissions inspection rules are separate and were not part of this review.
The North Carolina State Highway Patrol, which enforces the state motor carrier safety rules and the federal safety and hazardous materials regulations, and can rate intrastate carriers' safety fitness.
In FMCSA SMS data for September 2024 to September 2026, tires were the most frequent violation group at North Carolina inspections, followed by lighting, inspection reports and high-severity license-related violations.
