Sell your semi truck for cash in Jefferson City the easy and convenient way

Two rows sit under Jefferson City and the scale between them is enormous. The Coy Mine works zinc underground with 130 people. The Coy Stone Plant Addition carries two, and Martin Marietta holds it on the approved producer list, matched at 1.12 miles.

The mine is one of five Tennessee rows controlled by Korea Zinc, and it sits in the eastern district with the Young workings and Immel. Between them those five carry 528 people under one foreign parent.

What separates the eastern district from anywhere else is where its trucks go. This town, Mascot and Strawberry Plains all lie within thirty miles of Knoxville, and the mine-to-mill haul roads are roads people live on. It is the only underground mining district on file whose truck traffic runs through suburbs.

That is the fact that shapes the equipment here, and it sits apart from the tonnage. A haul road across private ground is a private problem. A haul road through a neighbourhood is a public one.

So the pattern is short repeated runs at moderate speed, with junctions, traffic, school times and sheeting discipline in the middle of them. Brakes, clutch and suspension take the load. Idle hours accumulate at gates and weighbridges rather than on a highway, and the top end of the engine barely gets stretched.

An ore hauler is heavy work regardless of the road: dense material, full loads, and a body taking the impact of loading every cycle, and that is as true of a Korea Zinc machine as of a contractor’s. If you are selling one out of the Coy Mine, the body and the frame are the first things anybody will want to see.

Those runs cross a county network that restricts a lot of itself. Jefferson County posts 11 of its 39 county-maintained bridges — 28.2 per cent, near the top of the state on that measure.

Note the size of the stock as well as the share. Thirty-nine county-maintained bridges is a small number, and a small stock with a high posted share is the profile of an older network that has not been rebuilt rather than a big one with a few weak links.

Within 10 miles of the Martin Marietta plant there are 123 structures and 25 posted, 12 of them county-maintained, the nearest 0.7 miles out. The lowest raw rating is 2.9 metric tonnes — below an empty tandem, so not a crossing this trade uses — and the cap that binds a loaded truck is 14.6 tonnes, about 16.1 US tons.

FHWA National Bridge Inventory 2025, Tennessee file, items 21, 41, 64 and 70. Operating rating is the gross weight of the rating vehicle.

Those crossings sit on top of a statute that hands the ore side and the stone side the same nothing.

Tenn. Code Ann. § 55-7-203 sets 80,000 lb gross, 20,000 lb on a single axle and 34,000 lb on a tandem, with up to 550 lb more for emissions-reduction equipment. Subsection (b)(7) grants a ten per cent margin of error on the weighing to logging, sand, coal, clay, shale, phosphate, solid waste, recovered materials, farm trucks and machinery trucks — off the interstate system only. Crushed stone is absent, and so are limestone, aggregate and gravel.

Tenn. Code § 47-26-812 adds an axle-citation shield and five hundred pounds for a natural resources load, from a weights-and-measures chapter about certified public weighers rather than the motor vehicle code. Off the interstate again.

And § 55-7-104 is the one that costs a working day: an overweight vehicle may not be moved until the load is reduced into compliance or a permit obtained, and failing to comply is itself a Class C misdemeanour.

Tenn. Code Ann. § 55-7-203 and § 55-7-104, and Tenn. Code § 47-26-812, as summarised by the University of Tennessee County Technical Assistance Service. Information, not legal advice.

Beyond the weight rules, the paperwork is one sentence.

Everything after that sentence is a fix rather than a category. A lost title has a counter replacement. Where none exists there is a bonded route. Neither one stops a sale.

The salvage rule is the one people repeat wrongly. Tennessee’s salvage and rebuilt part is built on the term passenger motor vehicle, and § 55-3-201 defines that as a vehicle ten model years old or less which, if it is a light-duty truck or a multipurpose vehicle, is rated at not more than nine thousand pounds gross.

So the seventy-five per cent threshold does not reach a truck rated above nine thousand pounds at any age, and does not reach a vehicle of any kind over ten model years old. Those limbs describe the class the part governs rather than exceptions inside it. Whether some other provision reaches such a vehicle was not determined and is not claimed here.

Tenn. Code Ann. § 55-3-201 and § 55-3-211, with the Tennessee Department of Revenue’s guidance. Information, not legal advice, and only as current as the day those were read.

All of that iron is iron we buy. Ore haulers and heavy tandem dumps off the Coy Mine. Plant trucks and loader support off the Martin Marietta stone addition, where two people run the whole thing.

Day cabs, road tractors, box trucks, straight trucks, flatbeds, rollbacks, tankers, service bodies, work trucks and pickups too — not a Jefferson County thing in particular, they run everywhere.

Whatever you drive, the offer doesn’t change. We buy all of them.

• Does it have to run?No. It does have to be complete — if the engine, transmission, doors, rear ends, drive shafts, wheels or anything under the hood have been removed, we can’t buy it. Rust is not a disqualifier.
• The engine is out of it. Is that different?Yes, and that is the line. A tired engine is fine; an engine that has been pulled and sold means we can’t buy the truck.
• What about the title?We need one unless the truck is old enough that it never had one. Lost titles have a counter replacement, and where none exists there is a bonded route.
• It ran the mine road through the houses for years.Then expect the wear in the brakes, the clutch and the suspension rather than the top end, whether it worked for Korea Zinc or hauled for them. That is the normal shape of a Coy Mine truck and not a fault.
• There is a posted bridge between it and the highway.Common here, where 11 of 39 county bridges are posted. It is exactly the case where buying it where it stands and arranging the tow beats anyone driving it out.
• How do you pay?Cash or electronic payment, whichever suits you.

Beyond a machine that has simply done its cycles, the reasons here are personal ones. Retiring. A medical that went the wrong way. A contract hauler losing a run to the mill and having one truck too many the week after.

The yards along the Coy Mine road and out across Jefferson County usually have one standing that came off a haul contract and never got another.

Most of those aren’t happy reasons, and we don’t treat them like they are. Somebody wants a straight answer and the truck gone by the end of the week. That’s what we’re here for.
