Fast 24/7 emergency response to get you back on the road quickly and safely.

Every CDL driver and owner-operator knows the dread of an unexpected breakdown on a remote stretch of highway. Whether you are hauling freight on I-40 through the Mojave Desert, running US-95 toward Las Vegas, or climbing the grades along US-93 toward Flagstaff, a mechanical failure can derail your schedule and threaten your CSA score. Weldon's Truck & Trailer provides 24/7 emergency roadside truck and trailer repair from our base in Kingman, AZ, with a 200-mile service radius covering Arizona, Nevada, and California. Our ASE certified diesel mechanics respond in fully equipped mobile service trucks, ready to diagnose and repair Class 8 semi trucks, trailers, and commercial motor vehicles on the spot — delivering fast roadside truck repair so you avoid towing costs, impound fees, and extended downtime.
Detailed Emergency Roadside Services
Our emergency response covers the full spectrum of roadside breakdowns. We perform on-site diesel engine diagnostics using factory-level scan tools for Cummins, Detroit Diesel, and PACCAR engines, allowing us to read fault codes, clear derates, and get your truck running without a tow to the shop. Our roadside capabilities include air brake repair, DOT roadside inspection preparation, electrical troubleshooting, cooling system repairs, and fuel system service. We provide fuel delivery for both diesel and DEF fluid, so you never sit empty waiting for a fuel truck. If your load has shifted in transit, our crew handles load shift correction and full cargo securement to get you back in compliance. For drivers facing an ELD clock crunch, we prioritize fast turnaround so you can avoid an out-of-service order and keep your CSA score clean. We also coordinate towing for vehicles that cannot be repaired roadside, working with trusted heavy-haul tow operators throughout our service area.
What's Included
Common Emergency Breakdowns We Handle
The most frequent emergency calls we receive involve tire blowouts on hot Arizona pavement, air brake system failures on mountain grades, overheating engines caused by coolant leaks or failed water pumps, and electrical failures that trigger engine derates or limp mode. We also see a high volume of aftertreatment system faults—DPF regeneration failures, SCR catalyst codes, and DEF quality warnings—that can put a truck into a forced idle. Transmission and driveline failures, broken fan belts, fuel filter restrictions, and turbocharger issues round out the most common roadside repairs our team handles along I-40 and US-93. Our technicians arrive prepared with the diagnostic tools and replacement parts needed to resolve these issues on-site.

Breakdown Service — Immediate Response for Any Truck Emergency
Our breakdown service covers the full range of mechanical failures that stop commercial trucks on Arizona, Nevada, and California highways. When a truck breakdown occurs — a blown tire, a failed air brake, an engine derate, or an electrical fault — a live dispatcher takes your call immediately and routes the nearest certified technician to your exact milepost. We do not use automated answering systems or callback queues. Every truck breakdown call is treated as urgent, and our goal is to have a technician on scene within 60 minutes for locations in our core service area. No hold music, no voicemail, no dispatch delays.
Mobile Mechanic — Onsite Truck Repair Without the Tow
Our mobile mechanic team operates from fully equipped service trucks carrying diagnostic scanners, common replacement parts, welding equipment, tire inventory, and brake components. The goal on every call is onsite truck repair — fixing the vehicle where it sits, without a tow to a shop. Our technicians are ASE certified and factory-trained on all major engine platforms, giving them the diagnostic capability to resolve most failures in the field. When onsite truck repair is completed, we verify the fix with a post-repair test and walk-around before releasing the vehicle to traffic.
Fleet Emergency Support & Driver Assist Programs
Fleet managers who dispatch drivers on I-40 and US-93 can establish a Weldon's account for priority response and simplified invoicing. When one of your drivers calls with a breakdown, our dispatch communicates directly with your operations team — providing ETAs, repair status updates, and documentation for your safety records. We accept Comdata, EFS, and all major fleet cards at roadside, and our digital work orders are formatted for carrier maintenance records and DOT file documentation.
