You pulled the oversize permit, mapped the route, booked the escorts — and the load still sits because the lowboy's third axle flagged a brake can at the yard. Heavy haul permit software gets the paperwork right, but the permit only covers the load; it never checks whether the rig is legal to carry it. That gap is where oversize moves actually die. Book a demo to see the rig-readiness side handled alongside your permits.
Heavy Haul Permit Software for Oversize Load Carriers
The permit clears the load. HVI makes sure the rig carrying it is inspected, maintained and DOT-legal — so a permitted move never gets killed by a brake can or a flat at the scale.
What the permit covers — and what it doesn'tthe half of an oversize move no permit system touches
Oversize load permit software is built to clear the load and the route: dimensions, weight, bridges, curfews, escorts. None of it looks at the condition of the equipment underneath. On a heavy haul rig, that second half is where roadside enforcement actually bites.
- Dimensions, weight & axle limits per state
- Approved routing around bridges and restrictions
- Travel windows, curfews and escort rules
- Superload engineering review and fees
- Pre-trip eDVIR on the tractor, trailer and dollies
- Brakes, tires and steering at max rated load
- Preventive maintenance so nothing's overdue mid-haul
- A signed, audit-ready record the move was legal
Run both halves and the permit actually gets used. Skip the second and you've paid for a permit, an escort and a crane window to watch a rig get red-tagged at the ramp. The fastest way to see the two run together is to book a heavy haul compliance demo.
Where an oversize rig fails inspectionthe stress points standard fleet checks miss
A heavy haul combination isn't a dry van with more axles. The things that put it out of service are specific to carrying a wide, tall, heavy load — and a generic daily check walks right past them.
HVI lets you build a heavy-haul-specific inspection template so these lines are actually on the walkaround — not assumed. You can set up oversize rig inspection templates once and every operator taps through the same critical points, every move.
The pre-dispatch oversize checklistthree phases that keep a permitted move legal to roll
This is the sequence a heavy haul carrier software workflow should enforce before a permitted load leaves the yard. Each phase is a gate — miss one and the permit is worth nothing at the first scale.
Rig condition verified
- Full eDVIR on tractor, trailer, dollies and jeeps
- Brakes checked and adjusted across every axle
- Tires inspected and inflated for max rated load
Maintenance current
- No preventive maintenance task overdue on this unit
- Any open defect closed or cleared by a work order
- Securement points, deck and lights signed off
Proof on file
- Signed, dated inspection record tied to the load
- Photos attached to any flagged or repaired item
- Record pullable in seconds at a roadside stop
Wire these three gates into your dispatch and a rig physically can't roll on a permit it isn't fit to carry. Start free and build your pre-dispatch gates on your own units.
What a cleared move looks like on filethe record that answers a roadside officer or an auditor
When a DOT officer stops an oversize load, the question isn't just the permit — it's whether the rig was inspected and maintained. This is the record HVI has ready, tied to the exact unit and move.
That's the difference between a stop that lasts ten minutes and one that ends your day. The same records roll up into fleet-wide compliance and inspection reporting you can show an insurer or a shipper on request.
Why a voided permit costs more than a ticketthe real price of skipping the rig-condition half
A brake defect flags on the pre-trip eDVIR. A work order opens, the can is swapped in 40 minutes, the move rolls on schedule with the fix on record.
The same defect gets found roadside. The rig is placed out of service, the permit window lapses, the escort and crane are re-booked, and the load sits under a tarp overnight.
Same defect, two very different days. The only variable is whether the rig was checked before the permit was ever used. See how carriers close that gap — book a demo on your heavy haul lanes.
From an operations lead who runs the permits and the rigswhere the real delays came from
Our permits were never the problem — we had those dialed. What killed us was a steerable dolly or a brake can nobody caught until the scale, and suddenly a permitted superload is sitting on the shoulder burning an escort crew. Now the pre-trip is on a phone, the dollies and jeeps have their own lines, and dispatch won't release a rig with an open defect. We stopped losing moves we'd already paid to permit.
Frequently asked questionsheavy haul permit & oversize load compliance software
Does HVI order or manage the oversize permits themselves?
No — HVI isn't a permit-routing or permit-ordering tool, so it won't replace your state portals or routing software. It owns the other half: the inspection, maintenance and compliance record that keeps the permitted rig DOT-legal. Book a demo to see how the two run side by side.
Can I build inspections specific to heavy haul equipment?
Yes. You can create templates with lines for steerable dollies, jeeps, multi-axle brakes and securement that a standard van checklist doesn't include. Set up oversize rig templates once, or book a demo to see sample heavy haul forms.
How does it help at a roadside inspection?
Your operator pulls up the signed pre-trip eDVIR, brake and tire sign-offs, and PM status for that exact unit in seconds — proof the rig was legal to carry the permitted load. Book a demo to see the roadside record.
Does it track preventive maintenance across multi-axle trailers?
Yes — PM triggers by mileage or engine hours on every unit, including trailers and dollies, so nothing goes overdue mid-haul. See preventive maintenance or book a demo for your rig mix.
How fast can an oversize carrier get started?
Most carriers are running digital pre-trips on day one and layer in PM and reporting over the first weeks. Start free with your unit list, or book a demo for a guided setup on your heavy haul fleet.
Make every oversize rig as ready as its permit
Heavy haul permit software gets the load cleared. HVI makes sure the rig carrying it passes — digital pre-trips built for oversize equipment, preventive maintenance across every axle, and an audit-ready record the move was legal. One platform, mobile in the yard, ready at the roadside.
