Full detailsWhere we run
From the bridges to the checkpoint and beyond
Laredo is one of the busiest trade gateways in the country, and nearly all of that freight funnels through a handful of roads. Commercial trucks cross at the World Trade Bridge and the Colombia Solidarity Bridge, stage and drop in the yards along Mines Road, and head north on I-35 toward San Antonio or east on US-59.
We work those roads every day of the year: the truck stops at I-35’s Uniroyal Drive exit, Love’s and Pilot on Mines Road, the warehouse districts off Killam Industrial Boulevard and Port Laredo, and the long rural stretches of US-83 and SH-359.

- FM 1472Mines Road (FM 1472)Laredo’s drayage spine: yards, warehouses, Love’s and Pilot, and the route to the Colombia bridge.

Questions drivers ask
Mobile diesel mechanic FAQ
Do you come to me, or do I need to get the truck towed?
We come to you. A mobile diesel mechanic drives to the truck — highway shoulder, truck stop, yard, dock, or customs lot — and repairs it there whenever the job can be done on site. If it truly needs a shop, we tell you up front so you can arrange a tow without losing more time.
Are you really open 24 hours?
Yes. Dispatch is open 24 hours a day, 7 days a week, 365 days a year — nights, weekends, and holidays.
What kinds of trucks do you work on?
Class 6 through Class 8 diesel trucks — semi trucks, 18-wheelers, and heavy work trucks — plus the trailers behind them: Freightliner, Peterbilt, Kenworth, Volvo, Mack, International, and Western Star tractors, day cabs, terminal (yard) tractors, box trucks, dump trucks, reefer trailers, and dry vans.
How much does a mobile diesel mechanic cost?
It depends on the repair, the parts, how far the mechanic has to travel, and the time of day. Describe the problem and your location when you call and ask for pricing up front.
How fast can a mechanic get to me?
That depends on where the truck is and what traffic looks like — bridge traffic on Mines Road and Loop 20 can change drive times quickly. Dispatch gives you an estimated arrival time on the phone.
Can you work inside a trucking yard or customs lot?
Yes, as long as the facility allows a service truck inside. Have your gate, guard shack, or yard contact ready when you call so the mechanic isn’t held up at the entrance.
Do you handle DOT inspections and fleet maintenance too?
Yes. Along with breakdowns, we perform DOT inspections and preventive maintenance at your yard so trucks stay out of the shop and on the road.
Not an emergency?
Schedule a repair or inspection
Need a DOT inspection, a PM service, or a repair on a truck that’s parked in the yard? Send a request and dispatch will call you back to set it up.
