Broken Down on the Interstate at 2 AM

The shoulder of I-75 at night is one of the worst places to be. Cars pass at 70 mph. You've got a blown steer tire, your air system just dumped, or the engine won't restart after a fuel stop. You dial three numbers — two go to voicemail. You need the one that answers.

We built our roadside operation around this exact moment. A real person picks up within rings, not minutes. A mobile mechanic truck that's actually stocked with parts, not just a tow hook, rolls to your mile marker. And if we can fix it right there — and most of the time we can — you're back rolling without ever seeing a shop.

How Our Roadside Assistance Works

From your first call to wheels rolling again — here's exactly what to expect.

1
Call Dispatch
Immediate

Call (423) 255-0896. A live dispatcher answers — no phone tree, no voicemail at 3 AM. Tell us what happened, where you are (mile marker, exit, truck stop), and what the truck is doing.

2
Location & Symptom Assessment
~3 minutes

We pinpoint your exact location, assess the symptoms over the phone, and determine which mobile unit to send. If it sounds like something our roadside trucks can handle, we dispatch immediately.

3
Mobile Unit Dispatched
Immediate

Your assigned mobile mechanic truck is rolling. We send a text with your tech's name, truck description, and estimated arrival time. Average response across our coverage area: 20-35 minutes.

4
On-Site Diagnosis
15-30 minutes

Tech arrives, secures the scene with cones and lights, and diagnoses the issue. No guessing — we use the same diagnostic tools our shop uses, just in a truck.

5
Roadside Repair or Tow Decision
Varies

If we can fix it safely on the shoulder, we do. Tire change, air leak, electrical issue, belt, hose, sensor — most common breakdowns are roadside-fixable. If it needs shop work, we tow it and you skip the wait for a second truck.

6
Back on the Road
Total: 1-3 hours

Once repaired, we verify the fix, you sign off, and you're rolling. Fleet card or direct pay accepted on the spot.

What We Fix Roadside

Our mobile mechanic trucks carry parts and tools for the most common diesel breakdowns. Roughly 70% of our roadside calls are resolved without a tow.

Tire Changes & Blowouts

Steer, drive, and trailer tire changes on the side of the road. We carry common sizes for quick swaps and can source others fast. Blowout cleanup and rim inspection included.

Air System Leaks & Repair

Air dryer failures, glad hand leaks, air line damage, governor issues, and brake chamber problems. Air system failures are one of the most common roadside calls — they ground you instantly.

Electrical & Starting Issues

Dead batteries, alternator failure, starter motor replacement, parasitic drains, and no-crank conditions. We carry batteries and test alternator output on-site.

Coolant Leaks & Overheating

Burst hoses, water pump leaks, thermostat failures. If you're overheating on a Georgia summer day, we stop the damage before it turns a hose replacement into an engine replacement.

Belt & Hose Replacement

Serpentine belts, fan belts, coolant hoses, turbo boots, and charge air cooler connections. We stock the most common sizes and can usually replace on-site.

Fuel System Problems

Bad fuel, gelling in winter, fuel filter clogs, primer pump issues, and air in the fuel system. We carry fuel filters and can bleed fuel systems roadside.

Brake Adjustment & Emergency Repair

Out-of-adjustment brakes are the #1 DOT violation. We adjust brakes roadside and handle emergency slack adjuster or air chamber replacement to get you past the scale house.

APU & Reefer Troubleshooting

Carrier, Thermo King, and aftermarket APU issues. Reefer failures on perishable loads are emergencies — we prioritize these calls to save your cargo.

What's on Our Mobile Units

Every truck we send is built to fix — not just diagnose and tow.

Fully Stocked Mobile Mechanic Trucks

Each mobile unit carries diagnostic scanners, air system components, electrical testing equipment, common filters and belts, tire changing equipment, batteries, coolant, and hand tools for most roadside repairs.

On-Board Tire Inventory

We carry a rolling inventory of common semi tire sizes — steer, drive, and trailer. For less common sizes, we coordinate with local tire shops for rapid delivery to your location.

Diagnostic Equipment

Same multi-protocol diagnostic scanners we use in the shop. We pull codes, run active tests, and make data-driven decisions roadside rather than guessing.

Real Roadside Calls We've Handled

Every breakdown is different. Here's how we've handled three common ones.

Interstate Emergency

Blown Steer Tire on I-75 at 3 AM

A driver blew a steer tire on I-75 near Exit 336 at 3:15 AM. Called us, our mobile unit was on scene in 22 minutes. Tire changed, rim inspected for cracks, torque verified. Driver was rolling by 4:10 AM.

Rolling in under an hour
Air System Failure

Air Dryer Failure Causing Brake Lockup on I-24

Truck pulled off I-24 near Lookout Mountain with brakes locked. Air dryer had failed, allowing moisture into the system and freezing the valves in cold weather. Our tech replaced the air dryer cartridge, purged the system, and tested all brake circuits roadside.

Truck Stop Breakdown

Engine Won't Start at a Truck Stop near Dalton

Driver at Love's Travel Stop near Exit 333 — truck cranked but wouldn't start after fueling. Our mobile unit diagnosed a faulty fuel pressure regulator. Had the part on the truck. Replaced it in the parking lot and verified fuel pressure was within spec.

Roadside Assistance FAQ

Most common breakdown causes: tire changes, air system leaks, electrical issues, belt and hose replacement, fuel system problems, brake adjustments, and minor coolant repairs. Our mobile trucks carry parts and tools for all of these. Roughly 70% of our roadside calls are resolved without a tow.
Depends on where you are relative to our dispatch position. For the Ringgold to Dalton stretch (Exits 326-350), typical response is 15-25 minutes. Calhoun area (Exit 312-317) is 25-35 minutes. Chattanooga metro (I-24/I-75 interchange) is 15-20 minutes. We give you an honest ETA when you call — not a fantasy number.
If the issue requires shop equipment or more extensive repair, we tow your truck to our Ringgold shop without needing a separate tow dispatch. You pay one bill. If you prefer a different shop, we'll tow you there. See our heavy duty towing page for towing details.
We maintain a rolling inventory of common steer, drive, and trailer tire sizes. For less common sizes, we coordinate with local tire distributors for rapid delivery — usually within an hour to your location. We also mount and balance on-site.
Pricing depends on the service needed, time of day, and location. We provide a clear estimate before any work begins. There are no hidden fees. Fleet card customers typically have pre-negotiated rates. Call us for a quote — (423) 255-0896.
Yes. Reefer failures on perishable loads are treated as priority calls. We troubleshoot Carrier, Thermo King, and most aftermarket APU and reefer systems. Temperature-sensitive cargo doesn't wait, and neither do we.
