How to Read an Oversize Load Permit: A Driver’s Review Checklist
Published by JaloPermit. A practical reading guide. Follow the issued permit, its attachments and current instructions from the issuing authority.
Start with the original permit and every attachment. A summary can help you find information, but the issued permit is the sole route authority. If a field is missing, a road name is ambiguous or two pages conflict, keep that question unresolved until the issuing office clarifies it.
This guide gives you a repeatable reading order. It does not promise a particular review time or replace permit-specific instructions.

- Resolve the gapsCompare the summary with the PDF. Ask the issuing office about conflicts.
This is a reading aid, not an issued permit or a clearance approval.
1. Confirm the document belongs to this move
Check the permit number, issuing jurisdiction, vehicle identifiers, load description and validity dates. Look for an amendment or replacement and make sure you are reading the current version. Confirm the dates cover the planned movement, including any delay.
Compare the permitted dimensions and weight information with the actual loaded vehicle. Read units carefully and distinguish overall length, trailer length and overhang. Gross weight alone does not answer an axle-weight or axle-spacing condition.
TxDMV's permitting guidance explicitly requires accurate vehicle and load dimensions and weight before applying. If the document and the actual move differ, contact the issuing office about correction before departure.
2. Trace the roads in sequence
For a routed permit, write down the origin, destination and each named road or junction in order. Check direction, business routes, frontage roads and ramps; roads close together on a map are not interchangeable.
Read exclusions and special instructions as well as the main route. Do not assume a map's shortest path matches the permit, or that a fuel stop has an authorized and physically suitable access route.
The FHWA route-planning training module discusses route surveys and potential obstructions. A map review does not replace a required survey or verification of conditions in the field.
3. Find escort and movement conditions
Read the permit, referenced rules and attachments together. Note the number and placement of escorts, any height-pole requirement, police involvement and segment-specific changes. Do not infer “no escort” from a blank extraction field.
Then record allowed hours, holiday restrictions, weather conditions and any advance notifications. Copy the actual time and location language; do not replace it with a remembered daylight rule from a previous move. For a quick pre-trip pass on just the time limits, see how to check curfews and travel restrictions in an oversize permit fast.
NYSDOT's special-hauling page illustrates why attachments matter: it separately provides escort information, holiday restrictions and supplemental-document requirements. Use the issuing authority's materials for your own permit. Minnesota is a good example: MnDOT’s General Provisions sheet says it is part of the permit, as our guide on how to read a Minnesota oversize permit explains. Michigan permits list numbered special provisions from a separate MDOT sheet, covered in our guide on how to read a Michigan oversize permit. Texas permits come out of TxPROS with turn-by-turn driving directions and published escort thresholds, covered in our guide on how to read a Texas oversize permit. Kansas permits come out of K-TRIPS, allow moves on holidays and set escorts over 14 feet wide or 16 feet high, covered in our guide on how to read a Kansas oversize permit. North Dakota permits come from the Highway Patrol’s E-Permits system and keep loads over 16 feet wide off the road on weekends and holidays, covered in our guide on how to read a North Dakota oversize permit. Wyoming permits come from the Highway Patrol, last no more than four days, and require a stop at the first port of entry, covered in our guide on how to read a Wyoming oversize permit. Pennsylvania permits come from PennDOT’s APRAS system, run five weekdays, and must travel with the Form M-938 conditions and urbanized-area map, covered in our guide on how to read a Pennsylvania oversize permit. Ohio permits come from ODOT’s OHPS system, travel with Form OS-1A, and put loads over 12 feet wide under rush-hour and late-weekend limits, covered in our guide on how to read an Ohio oversize permit. Illinois permits come from IDOT’s ITAP system, travel with Form OPER 993, and step travel times down by size — including a 9 a.m.–3 p.m. CST window for the biggest loads — covered in our guide on how to read an Illinois oversize permit.
4. Read the special instructions
Check for bridge speed or lane instructions, utility coordination, railroad crossings, notification requirements and other move-specific conditions. Where a condition refers to another document, obtain it. Never treat a short app summary as proof that there are no additional conditions.
The FHWA trip-operations manual covers pre-trip coordination and paperwork review. Share the relevant documents and unresolved questions with dispatch and the escort team before the move.
Compare the card with the original PDF
In JaloPermit, upload a supported original PDF with readable text. On a completed card, select Original permit PDF to preview a retained upload, move between pages or open it separately. Compare one category at a time: identity, dimensions, route, escorts, dates and restrictions.
Support varies by layout and available route information. Dashed or unresolved map sections need review. A bridge alert is supplementary; missing alerts do not prove clearance or weight capacity. To check structures against state DOT clearance lists and posted signs, see bridge clearance maps for trucks compared.
Keep your own copy of the issued permit and attachments in the form the authority requires. The preview is convenient access, not a substitute for your document-retention process.

FAQs
Can I follow a different route because a map shows a closure? Do not treat a navigation detour as permit authorization. Follow the permit's instructions and contact the issuing office about an authorized change when needed.
What if the card and PDF disagree? Use the original permit as the route authority. Resolve the discrepancy before relying on the summary; a missing card field is not permission to ignore a condition.
Does every permit have the same sections? No. Layouts and permit types differ, and conditions may be in attachments or incorporated rules. This reading order is a checklist, not a promise about every document's format.
Can I open my original upload again? Completed JaloPermit cards include Original permit PDF when the file is retained. Keep your own copy as well, including any attachments the upload did not contain.
