UST Roadside

24/7 Mobile Semi Truck Repair

A fully staffed mechanic truck, ready to come to you — day or night. Can't fix it roadside? We'll tow you straight to our yard for full-service repair.

What We Fix On-Site

Our Truck Shows Up Stocked And Ready.

If it's a semi-truck problem, our mechanics have run into it before.

Tires & Blowouts

Roadside tire repair and replacement, day or night.

Jump Starts & Batteries

Dead battery, bad alternator — we get you running again.

Brakes

Brake issues fixed on-site so you're not sitting out of service.

Fuel Delivery

Ran out on the shoulder? We bring fuel straight to you.

Belts & Hoses

Worn or snapped belts and hoses, replaced in the field.

Lockouts

Locked out of the cab? We'll get you back in and moving.

Electrical

Lights, wiring, and electrical faults diagnosed and fixed roadside.

Air Lines & Couplers

Air system and coupler repair to keep your rig DOT-legal.

And Everything Else

Our mechanics handle general semi-truck repair issues beyond this list — if it's keeping your truck off the road, call it in.

When It's Bigger Than Roadside

We Tow You Straight To Our Yard.

Some jobs need a shop, not a shoulder. When that's the case, we don't leave you to find someone else once you're already stuck — we tow your truck straight to our Hesperia fleet yard and get it handled there.

● No scrambling for a second shop once you're already broken down
● One team, start to finish — roadside triage through full repair
● Same mechanics who know semi trucks, not a general auto shop
