Best Route Planning Software for Oversize and Overweight Trucking (2026 Comparison: JaloPermit, oversize.io, ProMiles, Trimble PC-MILER, AASHTOWare)

You have an issued permit. You need to roll in four hours. The last thing you want is 30 minutes of cross-referencing a PDF against a state DOT map, a separate escort chart, and a bridge database you found on a forum three months ago.

The right software handles that work before you leave the yard. The wrong one makes you think it did—then leaves you guessing at a low bridge on a state highway at 5 AM.

This comparison covers the tools that come up most when drivers and dispatchers search for oversize and overweight route planning: JaloPermit, oversize.io, ProMiles (AASHTOWare PermitRoute), and Trimble PC-MILER. Each one solves a different problem for a different person. Knowing which is which saves time and, more importantly, keeps you legal.

What "Route Planning" Actually Means for OS/OW Moves

Generic GPS finds the fastest path. OS/OW route planning finds the legally cleared corridor—then checks what's on it.

Not the same thing. A standard navigation app does not know your load is 14 feet 6 inches tall, that your permit restricts you to specific highway segments, or that the state requires a pilot car when width exceeds 14 feet. The FHWA's guidance on permitting oversize and overweight vehicles is clear on this: the permitted route is a legal document, not a routing suggestion.

Good OS/OW route planning software starts with that legal document and builds outward from it.

The Tools, Head to Head

JaloPermit

Best for: independent owner-operators and small dispatchers (1–10 trucks) running OS/OW loads

JaloPermit is built for the permit-in-hand moment. Drop the permit PDF into a browser tab. Seconds later, you get a structured route card: permitted corridor, load dimensions, escort requirements, curfews, turn-by-turn directions. No account. No install. No subscription.

What separates it from everything else on this list is the infrastructure overlay tied to your specific route—not a generic truck map. The card shows:

• 870-plus weigh stations, with highway and milepost detail where the state publishes it
• 1,732-plus major-brand truck stops along the permitted corridor
• Low-bridge clearance alerts checked against your load's actual height
• Escort requirements cross-referenced against state thresholds for your dimensions

It handles any US state's permit format, as long as the PDF has a text layer. The route opens directly in Google Maps from the card. Share it by link or text it to a group chat in one tap.

Pricing is freemium. Three free decodes per day, no card required. Beyond that, $3.50 per decode. No subscription tier.

The Atlas—JaloPermit's built-in reference covering legal limits and escort rules for all 48 lower states in plain English—is accessible without uploading a permit. Useful for pre-move research before the permit even arrives.

What it does not do: JaloPermit does not generate a permit. It decodes the one you already have. If you need pre-move quoting or permit acquisition, that is a different tool.

oversize.io

Best for: brokers and carriers doing pre-move cost estimation and route feasibility before a permit is issued

oversize.io is a quoting and routing platform aimed at the broker and carrier side of the transaction. It answers "can we move this load on this corridor and what will it cost?"—before the permit exists.

It does not accept an issued permit PDF and does not produce a driver route card from one. It's account-based, with plans starting at $29/month. If you are standing at the yard gate with a permit in hand, oversize.io is not the tool for that moment.

Where it earns its place is earlier in the workflow: load planning, lane pricing, carrier-side feasibility. For brokers managing high volumes of OS/OW quotes, it is purpose-built. For an owner-operator who just received a permit from dispatch, it is the wrong tool entirely.

ProMiles / AASHTOWare PermitRoute

Best for: drivers in states with full PSDC integration, or state DOT agencies managing permit workflows

AASHTOWare PermitRoute—often surfaced through ProMiles on the driver side—provides free, turn-by-turn OS/OW navigation. That "free" is real. No cost to the driver.

The hard constraint is coverage, and it is a hand-off rather than a routing engine: the driver app needs a permit ID issued by a partner agency, so if the state that issued your permit is not integrated, there is no route to replay for that leg. Treat any specific deployment percentage with caution — the published figures describe a share of permits issued rather than a share of states, they are several years old, and different vendor pages give different numbers.

There is no PDF upload workflow. You cannot drop your issued permit in and get a route card out. No weigh station overlay, no truck stop mapping, no low-bridge alert tied to your load's dimensions. App installation required.

For drivers running loads entirely within a PSDC-integrated state, it is a solid free option. For multi-state loads or any state outside that network, the coverage gap is a real operational risk.

Trimble PC-MILER

Best for: large carriers, TMS vendors, and enterprise fleet operations

PC-MILER is the routing standard for large-scale trucking operations. It is embedded in most major TMS platforms, handles complex routing at scale, and the data quality is high.

It is also priced for operations, not individual moves. PC-MILER is licensed per seat — the browser-based PC*Miler Web starts around $85 per user per month, with no free tier — and it has no issued-permit PDF parsing. It is built for a fleet operations team—not a driver at 6 AM with a permit on their phone.

If you run 50-plus trucks with a dedicated routing team, PC-MILER belongs in your stack. If you are an owner-operator or a dispatcher managing five trucks, the per-seat pricing is hard to justify for occasional OS/OW moves.

Side-by-Side Comparison

Verdict: Which Tool for Which Persona

Owner-operator running OS/OW loads: JaloPermit. You have the permit. You need the route card, the escort check, and the infrastructure overlay before you roll. Three free decodes a day covers most single-truck operations at no cost.

Small dispatcher managing 1–10 OS/OW trucks: JaloPermit. The shareable route card goes straight to a group chat. One decode covers the driver brief. At $3.50 per decode beyond the free tier, the math works even on busy days.

Broker or carrier doing pre-move feasibility: oversize.io. Built for that workflow. Do not try to use it at the yard gate.

Driver in a PSDC-integrated state, no permit PDF to parse: ProMiles / PermitRoute. Free, functional, and purpose-built for turn-by-turn OS/OW navigation where it works.

Large carrier or TMS-integrated fleet: PC-MILER. The enterprise standard for a reason—if you have the team and budget to run it.

The Gap Nobody Else Fills

Three things sit in a gap that none of the other tools on this list address together: the permit-in-hand moment at the yard gate for any state's issued permit, infrastructure overlay tied specifically to the permitted route rather than a general truck map, and no-account browser-native access for independent and infrequent OS/OW operators.

That gap is exactly what JaloPermit was built for.
