Broken Down Right Now? Do This First

1. Get to the safest spot you can. The shoulder, an exit ramp or a rest area if the truck will still roll.
2. Turn on your hazard flashers right away.
3. Set out warning triangles. Federal rules require them within 10 minutes of stopping on the road.
4. Call 608-756-2916 and tell us where you are.
5. Wait somewhere safe, away from the traffic lanes and the driver's side of the truck if you can.

What to Tell Us When You Call

• Where you are: highway, direction of travel and the nearest mile marker, exit or cross street
• Your truck and trailer: year, make, model and unit number
• What happened: noises, warning lights, fault codes, smoke or leaks
• Your situation: whether you're loaded and whether the truck is blocking a lane
• Who you drive for: carrier or fleet name, and a PO number if you have one

Don't have every detail? Call anyway. We'll work with what you know.

24/7 Semi Truck Roadside Assistance That Comes to You

Breakdowns don't wait for business hours, and neither do we. Our roadside team runs around the clock, nights and weekends included. When you call, you get an ETA, location tracking and status updates, so you know help is coming instead of wondering.

Every hour on the shoulder costs you: a missed delivery window, a waiting customer, drive time burning away. Our job is to get you rolling again as fast as safely possible, or get you and your load to a plan that works.

How a Roadside Call Works

1. You call 608-756-2916. A service advisor takes your location, truck details and what's going wrong.
2. We dispatch the nearest service truck. One of our 6 mobile units heads your way and you get an ETA, typically 60 to 90 minutes in our service area.
3. Your technician diagnoses on the spot. Professional diagnostic tools find the actual problem instead of guessing at parts.
4. Most fixes happen right there. Our trucks carry commonly needed parts, so many breakdowns are repaired in one visit.
5. Shop backup if it needs a bay. If the repair can't be done roadside, your truck goes to our Janesville shop and the same team finishes the job.

Common Breakdowns We Fix on the Roadside

These are the calls we get most from drivers stranded on the road. Air and brake problems are a priority because they can leave you unable to move or out of service.

• Air leaks and brake problems: low air warnings, leaking air lines and brakes that won't release or adjust
• Flat and blown tires: steer, drive and trailer tire repair or replacement on the shoulder
• Overheating and coolant leaks: burst hoses, radiator leaks and overheating warnings before they turn into engine damage
• Loss of power and derates: aftertreatment, EGR and DPF faults that drop the truck into limp mode
• No-starts: dead batteries, failed starters and alternators that leave you sitting
• Electrical and lighting failures: wiring faults, dash warnings and trailer lights that can get you written up
• Transmission and clutch trouble: slipping, grinding or a truck that won't go into gear
• Trailer breakdowns: trailer air lines, brakes, lights and tires

If a repair needs a shop bay, we'll get your truck to our Janesville shop at 3248 S Tower Drive and keep working on it there. You won't start over with a stranger's shop. We use factory-grade OEM parts, backed by a 12-month parts warranty per manufacturer terms.

Winter Breakdowns in Wisconsin

Cold snaps bring their own roadside calls: batteries that won't crank, frozen air lines, gelled fuel and DEF problems. Our techs work through Wisconsin winters day and night. We'll diagnose the problem where you sit and either fix it there or get the truck to our shop to thaw out and repair.

A little prep prevents a lot of winter breakdowns. See our winter preventive maintenance checklist and common winter brake mistakes.

RV Roadside Assistance

A breakdown on the way to the campground or the Dells is no fun. Our technicians handle many of the same problems on diesel RVs and motorhomes that they fix on trucks: tires, brakes, cooling systems, batteries and electrical faults. Call 608-756-2916 and we'll send a tech to you. Learn more about our RV repair.

Roadside Help for Fleets

When one of your units goes down, you need one number that answers at 2 a.m. Fleet accounts get priority scheduling and preferred pricing on roadside and shop work, so your trucks come first. Save 608-756-2916 in every driver's phone and the first call after a breakdown comes straight to us.

For scheduled work like preventive maintenance and DOT inspections in your yard, see our mobile truck repair and fleet services.

• A real shop behind every call. If it can't be fixed roadside, our own shop finishes the job.
• 12-month parts warranty on parts we install, per manufacturer terms.

Truck Roadside Assistance FAQ

How fast can you get to my breakdown?

Is roadside assistance really available 24/7?

Yes. Roadside service runs 24 hours a day, 7 days a week, including nights and weekends. Our Janesville shop is open Monday to Friday, 7 a.m. to midnight.

Where do you provide roadside service?

Along I-39/90, I-43 and the main highways around Janesville, Beloit, Madison, Monroe and Rockford. We take occasional calls as far north as Wisconsin Dells. Call and we'll confirm.

What can you fix on the roadside?

Most common breakdowns: air leaks and brakes, tires, overheating, no-starts, electrical faults, derates and trailer problems. If the truck needs a shop bay, we'll get it to our Janesville shop.

Do you tow semi trucks?

If your truck can't be repaired roadside, we'll get it to our Janesville shop for repair. Tell us when you call and we'll plan it.
