Hauling logs and timber in NC: rules for log truck drivers

The short version

North Carolina lets trucks hauling raw logs, wood chips and other forest products run up to 90,000 pounds gross. The catch: only inside the state, off interstates and within posted bridge limits. [1]

Overweight fines for forest products are half the normal rate, but they still add up. Officers can send you to a scale up to five miles away. [1][4]

Logs have their own federal securement rule, 49 CFR 393.116. A load hanging more than 4 feet past the rear needs a flag, and a light at night. [2][8]

The federal farm hours-of-service exemption does not cover timber or wood pulp. Most log haulers who skip the log book do it under the 150 air-mile short-haul exception. [11][12]

Everything here is as of October 2026. Statutes change, so read the current text on ncleg.gov before you load heavy. [1]

How big the wood business is

NC State Extension says the forest sector, including logging, sawmills, furniture and pulp and paper, directly employed about 66,500 people in 2024. [13][14]

Counting spending that ripples out, it put the sector's total at about $41.7 billion in output and about 140,900 jobs. That makes it the state's second-largest manufacturing sector, just behind food. [13]

Not every part grew. Total jobs fell about 1.9% from 2023, with most losses in solid wood products. Forestry and some paper lines gained slightly. [14]

Big mills set the hauling pattern. Domtar's Plymouth mill on the Roanoke River makes fluff pulp, with capacity of 390,000 metric tons a year and about 362 workers as of late 2025. [18]

Markets also close. The Canton paper mill in Haywood County shut in June 2023 after 115 years, and the loss reached loggers and foresters across the region. [20]

In January 2026, International Paper finished selling its pulp business, nine plants in all, to funds tied to American Industrial Partners. Our tip: if you haul to one of those pulp mills, confirm the receiving rules haven't changed. [19]

The 90,000-pound forest products exception

G.S. 20-118(c)(12) sets aside the normal weight limits for certain loads hauled within NC. The list includes forest products from a farm or woodlands to market, wood residuals like chips, sawdust and bark, and raw logs to market. [1]

The truck must also stay off interstate highways and must not exceed any posted bridge weight limit. [1]

It must match one of three setups. The first allows 22,000 pounds on a single axle, 42,000 on a tandem and 90,000 gross. [1]

The second is for combinations with five or more axles: 26,000 single, 44,000 tandem and 90,000 gross. You need at least 48 feet from the first axle to the last, and 11 feet between the first two. [1]

The third is a two-axle truck at up to 37,000 pounds gross, with no more than 27,000 on one axle and at least 14 feet between the axles. [1]

Under the normal rules, the limits are 20,000 pounds on a single axle and 38,000 on a tandem, with gross set by the bridge table. The exception is a real gain, but only on the right roads. [1]

Where the exception ends

The interstate is the hard line. Once you get on I-40, I-95 or any other interstate, normal federal and state limits apply, so plan a route that reaches the mill on US, NC and secondary roads. [1]

Posted bridges still rule. G.S. 20-118(g) says nothing in the statute allows gross weight over a bridge's posted safe capacity. [1]

Light-traffic roads are the small state roads posted below normal axle limits. Under (c)(5), forest products may exceed those posted limits from where the load starts to either of the two nearest roads that aren't light-traffic roads. [1]

NCDOT can revoke that light-traffic exception on a road it finds is being damaged. It then posts the road "no exemptions." Our tip: watch for those signs near the deck. [1]

The normal 10% tolerance doesn't help here. It never goes above single or tandem limits or 80,000 pounds gross, and we found nothing that adds tolerance above 90,000. [1]

A federal bill, the Safe Routes Act (H.R. 2166), would let log trucks use interstates for up to 150 air miles at state forest-products weights. It was introduced in March 2025 and isn't law as of October 2026. [23]

Overweight fines and plates

For a single or tandem axle over the limit, NC charges 4 cents a pound for the first 1,000 pounds, 6 cents for the next 1,000 and 10 cents for each pound after that. [1]

For gross or axle-group overweight, it's 2 cents a pound for the first 2,000, 4 cents for the next 3,000 and 10 cents over 5,000. Forest products listed in (c)(5) pay half. [1]

Our math as an example: 3,000 pounds over on a tandem is $200 at the normal rate, or $100 for a forest products load. [1]

An officer can weigh you on the spot or send you to a scale within five miles. The officer can hold the truck until the extra weight comes off, and that wood is the owner's problem. [4]

Farmer-rate plates cost $1.25 per 100 pounds for trucks over 17,000 pounds, against $2.75 at the general rate. They can cover a farmer's own logs and pulpwood. [5]

Farmer plates can't be used for hire. If you haul other people's wood for pay, you need the general rate. We found no separate log truck plate in G.S. 20-88. [5]

Overhang, flags and length

Under G.S. 20-117, a load sticking out more than 4 feet past the rear needs a red or orange flag at least 18 inches square. From sunset to sunrise, it needs a red or amber light seen from 200 feet. [2]

NC caps rear overhang at 14 feet, but that cap does not apply to vehicles hauling forestry products or utility poles. [2]

Commercial trucks must also meet 49 CFR 393.87. A rear load 2 feet wide or less needs one flag, and a wider load needs two. Side projections over 4 inches need flags too. [2][9]

Normal length rules still apply: 40 feet for a single truck and 60 feet for a combination, though a tractor with a semitrailer up to 53 feet may run longer. Height is capped at 14 feet. [3]

Securing logs under 393.116

The log rule covers most log loads. Banded logs and loads of four or fewer processed logs may use the general rules, while firewood, stumps, debris and short logs must ride in a box closed on all sides. [8]

The truck must be built or adapted for logs, with bunks, bolsters, stakes or standards that cradle the load and keep logs from rolling. [8]

Logs must be solidly packed. Each outside log touches at least two stakes, bunks or standards, and the middle of the top outside log must sit below the top of each stake. [8]

On a frame or flatbed truck, the tiedowns on a stack must have a combined working load limit of at least one-sixth of that stack's weight. Add tiedowns when the wood is slick. [8]

Shortwood loaded crosswise needs at least two tiedowns per stack, near one-third and two-thirds of the log length. Lengthwise longwood sits in two or more bunks with at least two tiedowns or wrappers. [8]

Pole trailers need a tiedown per bunk or two wrappers, with front and rear wrappers at least 10 feet apart. Big logs that ride above the bunks need two more wrappers. [8]

Hours of service: no farm exemption for timber

The federal farm exemption in 395.1(k) covers agricultural commodities. FMCSA's 2020 rule says that does not include timber cut for lumber, wood pulp or related products. [10][12]

FMCSA noted that some states had treated timber or wood chips as farm products. Those haulers lost the farm hours exemption. Don't mix this up with NC's weight rule, which does cover forest products. [1][12]

Your main relief is the short-haul exception in 395.1(e)(1). You need no log if you stay within 150 air miles of your work reporting location and get released within 14 hours. [11]

You also need 10 hours off between shifts, and the carrier must keep your time records for 6 months. Go past 150 air miles and the normal log and hour limits apply. [11]

At the deck and on the road

NC's Forest Practices Guidelines say a logging road entrance onto a paved road must be built and kept up so sediment and debris don't end up on the road and wash into a stream. [17]

That duty falls on the logging job. Still, a driver pulling out of a muddy deck should know the rule exists. The same guidelines bar using a stream channel as a road. [17]

On the highway, G.S. 20-116(g) says a load must not fall, blow, sift or leak off the truck. Bark and chips count, so check for gaps before you roll. [3]

Western NC still feels Helene. The NC Forest Service counted about 822,000 acres of damaged timberland worth an estimated $214 million, heaviest around Buncombe and McDowell counties. [15][16]

In spring 2025, western NC mill and logging sources described quotas at mills, too few loggers and tangled salvage wood that calls for extra care on the road. Our tip: ask the mill about quotas before you haul. [21]

The North Carolina Forestry Association's ProLogger course trains logging businesses, with instructors from the Highway Patrol's motor carrier unit. NCFA says some companies check its ProLogger list before a logger delivers wood. [22]
