Dump Trucks, Gravel and Construction Traffic on Highway 418 in Fountain Inn

By Tom Conits · Greenville personal injury attorney · September 21, 2026

This post is about the trucks that come with construction traffic, the dump truck with a load of gravel, the roll-off, the lowboy with an excavator on it, and one road: Highway 418 through Exit 23 in Fountain Inn, which the city's 2017 plan lines with industrial and commercial land. A wreck with one of those trucks can turn on a South Carolina load statute, on who loaded the truck, and on evidence the same statute tells the driver to have cleaned off the road. If gravel cracked your windshield, start with the load statute; if you were hit, start with what to do. I serve Fountain Inn personally.

What the City and SCDOT Say About Highway 418

Highway 418 changes names as it crosses Fountain Inn. SCDOT's sheets and the Census Bureau's road files carry it as Milacron Drive west of the interstate, McCarter Road through Exit 23 to South Main Street, then Knight Street and Gulliver Street. The junction residents described to the city in 2023 as a four-way stop is on the west side, where the highway meets Fairview Street Extension and Greenpond Road. I've been through that junction, and it was busy every time. I drove through it in September 2026, and the light was working. The business park in my first Fountain Inn truck post has a Milacron Drive address, between that junction and the ramps, and the sentence I wrote about it there stands: I've driven Milacron Drive at shift change; the trucks are no joke. Those three things I can say first-hand; McCarter Road and everything else about this road come from public documents, named as I go, or are marked as a general statement.

SCDOT's count sheets carry the stretch from Fairview Street Extension to South Main Street, the Exit 23 interchange included, as one station, at an estimated 17,200 vehicles a day in 2025, up from 12,600 in 2020, against 7,600 at the next station west, between Highway 651 and Fairview Street Extension. The city's 2017 Master Plan said two-lane rural roads are built for "around 10,000 trips per day," called Highway 418 "chief among the violators," said the highway east of I-385 was then "operating at approximately one-hundred percent" of its designed volume, and reported the Highway 418 project thirty-first on the regional list, which staff estimated at the time meant completion "fifty (50) years in the future."

In the city's 2023 comprehensive-plan survey, "Highway 418 and intersections" was the first transportation priority. One written answer, dated May 1, 2023, says the four-way stop "is sometimes busier than mere stop signs can handle"; another, from March 25, writes of "Tons of traffic with large trucks" on Highway 418. City planning staff still called the junction "the four-way stop at Milacron Dr. and Fairview Street Extension" in an October 2024 report to City Council. The Fountain Inn Police Department's year-end collision maps, in the council's January 2025 and January 2026 packets, list "Fairview St Ext & Milacron Dr" among the city's collision hot spots for 2024 and again for 2025. The mayor's January 2026 column reports one fix: the signal at the southbound Exit 23 ramps "turned on in 2025." The federal rail-crossing inventory estimates 8 percent trucks on McCarter Road at the tracks, without dating the estimate.

What Is Being Built Along Highway 418

The city's 2017 plan designated 161 acres between I-385 and Greenpond Road for industry and, with two named exceptions, both sides of the highway from I-385 to just past South Main Street for commercial use, and said the property around the intersection of Milacron Drive and Fairview Street Extension was suited to "any sort of commercial travel center or truck stop." The mayor's August 2026 column reports that a new store had broken ground on Highway 418 near I-385.

Building and paving move by truck: dump trucks, roll-offs hauling debris out, lowboys bringing excavators in, concrete mixers. That is a general statement about construction, not about any site: no source named here says which trucks serve which site or ties any crash on this road to any project, and neither do I.

One project on McCarter Road is public record, and it is here for the ambulance route, not for its trucks. The Greenville Journal reported that Prisma Health broke ground on June 30, 2026 on a $180 million, 50-acre medical campus at 351 McCarter Road, expected to be complete by December 2027; Greenville Business Magazine reported the next day that site preparation was under way. Neither report mentions an emergency department, so ER routing is still what my Fountain Inn page says.

Gravel, Stone and South Carolina's Load Statute

My single-vehicle crash post covers the general rule in S.C. Code § 56-5-4100(A): a vehicle must be built or loaded so nothing escapes. Subsections (B) and (C) are written for loads like the ones in this post.

The load rule. A truck or trailer loaded with "rock, gravel, stone, or other similar substances which could blow, leak, sift, or drop" may not move on a highway unless the load, measured "against all four walls," sits at least six inches below their tops "when loaded at the loading point" (a load that is not level may peak as high as the tops, no higher), or is "securely covered by tarpaulin or some other suitable covering," or the vehicle is built so nothing can escape (subsection (B)); the same subsection takes in "garbage or waste materials" headed to a refuse site.

The sweep duty. "The loader of the vehicle and the driver of the vehicle" must sweep or otherwise remove loose gravel from the running boards, fenders, bumpers and similar exterior parts "before it is moved on a public highway" (subsection (C)). Two roles are named, and only one of them rides in the cab, so the statute points at whoever loaded the truck as well as whoever drove it; the hub explains why a second responsible party matters.

What the statute does not say. Subsection (B) does not list sand, dirt or asphalt as loads; they come in, if at all, as "similar substances." Its penalty is a fine of one hundred dollars, and nothing in it says a violation proves a civil case; what it does say is "Nothing in this section bars a claim for damages." Forest products are exempt, one reason log trucks are a different case. Rock and gravel are not.

Equipment Moves and the Rail Crossing on McCarter Road

The tracks at Main Street. The Federal Railroad Administration's inventory lists a gated, single-track crossing on McCarter Road (SC-418), interconnected with the traffic signal at a nearby intersection, and puts the intersecting road about 25 feet away; the maps show that road is South Main Street. A commercial driver may not enter a crossing "without having sufficient space to drive completely through the crossing without stopping" (49 C.F.R. § 392.12), and S.C. Code § 56-5-2725 requires notice to the railroad and a full stop before slow or low-clearance equipment crosses tracks. The FRA has one collision on file there, from 1991, when its record lists only crossbucks at the crossing: a truck-trailer stopped on the tracks, no one hurt.

When the Truck Belongs to the County, the City or SCDOT

The mayor's January 2026 column credits SCDOT with repaving "much of Highway 418" in 2025. Two things change when the dump truck is the government's own. Unless a rule specifically says otherwise (the commercial driver's license rules do, § 390.3T(b)), the federal safety rules "do not apply to" transportation "performed by the Federal government, a State, or any political subdivision of a State" (49 C.F.R. § 390.3T(f)(2)); South Carolina's load statute, with its listed exceptions, and ordinary negligence still do. And the clock is shorter: the South Carolina Tort Claims Act generally gives two years to sue, not three (S.C. Code § 15-78-110); my injury deadline traps post has the rest.

Here "the government" can mean SCDOT, the City of Fountain Inn (the Census Bureau's boundary puts this stretch inside the city limits), Greenville County or, past the county line, Laurens County. A private contractor on a public job is different: the Act's definition of a government employee "does not include an independent contractor" (§ 15-78-30(c)), so that company is generally sued like any other.

What To Do After a Dump Truck Wreck on Highway 418

The hub's general truck-crash steps and my first post's Fountain Inn steps apply. This kind of wreck adds its own; the first two are urgent.

• Photograph the load before the truck leaves, from a safe spot off the road. How high it sits against the walls, the tarp, the tailgate, and the running boards, fenders and bumpers, where subsection (C) says loose gravel should not be.
• Photograph the pavement before it is swept, if you can do it safely. Subsection (E) orders the operator to make "every reasonable effort to immediately cause the public highway to be cleaned," and lets SCDOT or any law enforcement officer clear it, if he does not, when it blocks the road or endangers safety. A driver who does what the statute orders also clears away the evidence.
• Get the door, and the box. My first post lists what to photograph on the truck and what to do with the USDOT number. New here: a roll-off container can carry a different company's name than the truck under it, so photograph both; and county, city or SCDOT markings generally mean the shorter clock above.
• Ask where it was loaded. The load rule is measured "at the loading point" and the sweep duty names the loader, so the pit, plant or job site that filled the truck can matter as much as the driver. If the driver hands the officer a load or scale ticket, ask to photograph it; a load ticket usually names the pit or plant that filled the truck. After a gravel wreck a preservation letter should go to two addresses: the company on the door and whoever loaded the truck.
• If it is the day after, or the truck never stopped, write down where and when, save the dashcam file before it overwrites, photograph the glass and any stone still in the car, get witnesses' names and numbers, and report it to police if no officer came; the second question below explains why.
• Get checked, then call me. Where the ambulance goes is on my Fountain Inn page. Fountain Inn is about 20 minutes from my office down I-385, and I make that drive for clients: kitchen table, front porch, hospital room. If home is out past Fairview Street Extension or off McCarter Road, I'll come to you there.

The interstate itself has its own guide, Wrecked on I-385?, and the hub's corridor guides link every local truck-road post on this site.
