ProMiles for Oversize and Overweight Routing: Features, Pricing, and Honest Trade-offs
ProMiles Permit Route Guidance comes up often when drivers and dispatchers search for heavy haul trucking software. (For the underlying rules these tools are all working against, the FHWA keeps a state-by-state compilation of truck size and weight limits.) It's free, it's been around, and it handles OS/OW routing. Those are legitimate points in its favor.
But before you build your pre-trip process around it, you should know exactly what it does, where it stops, and what it leaves uncovered. Here's the full picture.
What ProMiles Permit Route Guidance Actually Does
ProMiles offers a permit route guidance product aimed at oversize and overweight moves. The core function is turn-by-turn navigation for OS/OW corridors, with routing that accounts for weight, height, and width restrictions.
It connects to state DOT permitting systems through PSDC (Permit System Data Collection) infrastructure. When a state is integrated and your permit was issued through a compatible system, ProMiles can pull route data and provide navigation guidance for that move.
That's a real capability. For drivers running corridors in states with strong PSDC integration, it can surface a legally appropriate route.
The App Requirement
ProMiles Permit Route Guidance requires installation. It's not a browser tab you open on the road — you download the app, set it up, and then use it. That's a friction point worth naming, especially for owner-operators who aren't managing a fleet of devices.
Pricing
The permit route guidance component has been positioned as free, and that's accurate for the basic guidance function. ProMiles also sells broader trucking software products — mileage and routing tools aimed at carriers and fleets — which carry licensing costs. The free guidance piece is separate from those paid products.
Where ProMiles Runs Into Limits
Coverage Is Incomplete
The PSDC integration model means ProMiles only works well where state DOT systems are connected. Not every state is. If your permit came from a state with limited or no PSDC integration, ProMiles may not have the route data to work with. You're not getting guidance — you're hitting a gap.
For a driver running an unfamiliar state corridor, "it depends on integration" isn't a reliable answer.
No PDF Upload Workflow
This is the biggest practical gap. If you have a permit PDF in hand, ProMiles doesn't let you drop it in and extract the route. There's no upload workflow. The tool depends on pulling data through state systems, not reading the document the state already sent you.
That matters because the permit PDF is what you actually have. It's the legal document. It has the route, the curfews, the escort requirements, the load dimensions. ProMiles can't read it.
No Infrastructure Overlay
ProMiles Permit Route Guidance doesn't show weigh stations on the permitted route. It doesn't show truck stops. It doesn't flag low-bridge clearances against your load height. You get navigation. You don't get the full picture of what's between origin and destination.
For a heavy haul move, those gaps add up. A weigh station you didn't know about. A bridge clearance that's close to your height. A truck stop that's off the permitted corridor. These aren't minor details.
ProMiles vs. Other Heavy Haul Trucking Software
Here's how ProMiles stacks up against the other tools that come up in this category.
Trimble PC-MILER
PC-MILER is the enterprise routing standard — precise, deeply adopted by carriers, and built for commercial truck routing. It is a paid product, though not an unreachable one: PC*Miler Web is browser-based and sold online at roughly $85 per user per month, alongside the licensed desktop and TMS editions. What it does not do is parse an issued permit PDF — it builds a route from dimensions you type in.
Oversize.io
Oversize.io is built for brokers and carriers in the quoting and planning phase, before a permit is issued. It's a pre-move tool that requires an account and subscription. If you already have the permit and need to understand what it requires, Oversize.io isn't the right tool for that moment.
Digital Permit Book
Digital Permit Book stores compliance documents for fleet managers. It's document management, not route extraction. It won't read your permit and tell you where the escorts kick in.
The Gap None of These Tools Fill
There's a specific moment in every oversize move that none of these tools own: the permit just arrived, the truck is in the yard, and the driver or dispatcher needs to understand what the permit actually requires before the wheels turn.
Not before the permit was issued. After.
ProMiles gets close to this moment but can't reach it without state system integration. The other tools don't try to reach it at all.
JaloPermit was built specifically for this moment. Drop the permit PDF in, get back a structured route card with the permitted corridor, load dimensions, escort requirements, curfews, and turn-by-turn directions. It reads the original permit PDF the state issued — any state's format — with no state-system integration required. It needs that original PDF rather than a photo or a scan of a printout.
The route card also overlays 870-plus weigh stations with highway, exit, and milepost data, 1,732-plus major-brand truck stops with exits and parking, and low-bridge clearance alerts checked against your load's height. Everything that can ground you, on one card, before you leave the yard.
No account. No install. Open a browser tab and go. Three free decodes per day, $3.50 per decode after that.
Working it out by hand takes 25 to 30 minutes. JaloPermit does it in seconds.

When ProMiles Makes Sense
ProMiles Permit Route Guidance is a reasonable option if you're running corridors in states with strong PSDC integration, you're comfortable installing and managing an app, and you don't need weigh station, truck stop, or bridge clearance data overlaid on the route. For drivers who run the same familiar corridors repeatedly and already know the infrastructure, the free navigation guidance has real value.
When It Doesn't
If you're running an unfamiliar state route, if your permit came from a state with incomplete integration, if you need to verify escort triggers against your load dimensions, or if you want to see every weigh station and low bridge before you roll — ProMiles leaves you with work to do.
The permit PDF in your hand already has the answers. The question is which tool can read it.
FAQs
Does ProMiles Permit Route Guidance work for all 48 states? No. ProMiles depends on PSDC state DOT integration, which isn't complete across all states. Coverage varies, and for states with limited integration, route guidance may not be available.
Can I upload a permit PDF to ProMiles? No. ProMiles doesn't have a PDF upload workflow. It pulls route data through state permitting systems, not from the document you have in hand.
Is ProMiles Permit Route Guidance free? The permit route guidance component has been offered at no cost. ProMiles also sells separate commercial routing and mileage products that carry licensing fees. The two are distinct.
Does ProMiles show weigh stations or truck stops on the permitted route? No. ProMiles Permit Route Guidance provides navigation for the permitted corridor but doesn't overlay weigh station locations, truck stop data, or low-bridge clearances.
What heavy haul trucking software reads an issued permit PDF directly? JaloPermit reads any state's OS/OW permit PDF — the original document, not a photo of one — and returns a structured route card with the corridor, escorts, curfews, weigh stations, truck stops, and low-bridge alerts. No account or installation required.
How does JaloPermit handle escort requirements? The escort checker runs your load dimensions against each state's escort thresholds automatically. You see whether escorts are required and under what conditions, based on what the permit already specifies.
What does it cost to use JaloPermit compared to ProMiles? ProMiles permit route guidance is free but requires app installation and state system integration. JaloPermit offers 3 free decodes per day with no account and no install. After the free tier, each decode is $3.50 — no subscription, no commitment.
The Bottom Line
ProMiles does one thing reasonably well: navigation guidance for OS/OW routes in states where it's integrated. That's a narrower use case than most drivers realize when they first hear about it.
If you have a permit in hand for an unfamiliar route and need to know escorts, curfews, weigh stations, and clearances before you leave the yard, ProMiles isn't built for that moment. Neither are the tools that handle the pre-permit phase.
That's the gap. JaloPermit fills it. Drop the permit. Roll legal.
