We Navigate Understanding Superload Requirements on I-80
Freedom Heavy Haul can offer expedited Pickup and Delivery for any size shipment anywhere in the USA. Contact us today for No Hassle, No Pressure Pricing.
We help teams move heavy, oversize loads with confidence. Our process aligns with the Ohio Department of Transportation rules and the state highway system. We explain when a vehicle load crosses into superload territory so planners know when a permit must obtained and route changes are needed.
ODOT marks a superload as any combination exceeding 120,000 lbs., wider than 14′-0″, or taller than 14′-6″. Daylight hours run from one-half hour before sunrise to one-half hour after sunset. The Director issues Special Hauling Permits under ORC 4513.34.
Safety guides every decision. We check legal dimensions, bridge limits, and traffic control plans to avoid delays. Unpermitted movement can trigger penalties under ORC 5577.12 and 5577.99, so documentation and number accuracy must carried through each application.
Our team coordinates with the department transportation and the Central Permit Office at 1980 West Broad Street, Columbus, Ohio 43223. We translate rules into a practical plan for escorts, timing, and compliance so your vehicles loads move on schedule.
Expert service for safe, compliant super loads on I‑80 across Ohio and beyond
We coordinate permits, escorts, and traffic control so heavy loads travel with minimal risk. Our team secures Trip and 90‑Day Continuing permits and plans authorized routes that meet Ohio Department standards. Moves run in daylight and avoid weekends or nights unless explicitly approved for safety.
What we handle
We manage every detail so your vehicles and each vehicle load move smoothly. We build route plans that check geometry, structures, utilities, and traffic control. We document weight, dimensions, and axle groups to ensure a permit must obtained without delays.
- Permit management: Trip and 90‑Day options, plus authorized stops for fuel, food, and rest.
- Routing: Clear plans that reduce impacts and protect infrastructure.
- Escorts & traffic control: Certified escorts and coordination with law enforcement and the state highway patrol for rolling roadblocks.
- On‑day operations: Driver briefings, checklists, and rapid escalation for changing conditions with OSHP support.
Why it matters
Safety guides every decision. We protect communities and assets by avoiding damage and by controlling speeds for oversize overweight moves. The result: on‑time deliveries, fewer surprises, and compliance that keeps projects on schedule.
Understanding Superload Requirements on I-80
C. When gross weight, width, or height exceed set limits, extra approvals follow. ODOT’s Operational Guide defines a superload as any unit with gross weight over 120,000 lbs., width beyond 14′-0″, or height higher than 14′-6″. Daylight moves run from one-half hour before sunrise to one-half hour after sunset.
How Ohio defines a “superload” under ODOT guidance
We apply those thresholds early to see if a load triggers added reviews. We verify size and weight data before filing. This prevents delays and keeps your vehicles compliant.
State highway context and interstate movements
The state highway system covers Interstate, U.S., and State Routes. Applications must list exact origin and destination that connect to that network. We check routing options for interstates and note when extra district coordination is required.
“Accurate axle and tire number entries are essential for structural review and safe routing.”
- We confirm escort needs and equipment requirements.
- We plan staging within daylight hours.
- We give drivers clear go/no‑go criteria before submission.

Legal dimensions, size and weight thresholds that trigger a permit
Early verification of width, height, and axle groups prevents costly rework. We measure each vehicle and load against ODOT guide lines to see if a special permit is needed. This saves time and avoids rejected filings.
Width, height, length, and overhang checks
ODOT sets width over 14′-0″ and height over 14′-6″ as trigger points. We confirm legal dimensions for length and front rear overhang. Deck height and length choices reduce clearance risk and keep stability during travel.
Axles and weight considerations
Axle groups matter. Single, tandem (≤16′), tri‑axle (≤16′), and quad‑axle (≤16′) spacing affects permitted loads. We compute gross weight and individual axle weights and check inner and outer bridge spans for structural limits.
- We translate legal dimensions into actionable specs for permit filings.
- We configure combination vehicles to spread weight and protect structures.
- We prepare a dimension and weight dossier for ohio department transportation review.
Parameter | Threshold / Note | Action |
---|---|---|
Width | > 14′-0″ | Flag for special permit; document side clearances |
Height | > 14′-6″ | Survey vertical clearances and plan escorts |
Axle Group | Single, Tandem, Tri, Quad (≤16′) | Calculate per-group weight and bridge spacing |
Gross Weight | Measured against spans and route limits | Adjust configuration or request permits issued above limits |
Permits must be obtained and carried: how ODOT issues Special Hauling Permits
Permits control timing, scope, and liability for every oversize overweight move. We verify whether a single trip, single trip & return, or a 90‑day continuing permit applies. This starts permit must obtained early so filings meet process windows.
Permit types and duration
Trip permits cover one-way moves. Single trip & return lets a unit go out and back. Ninety‑day continuing permits handle repeated movements over a set period.
Office hours, transmission, and format
The Central Permit Office accepts applications Monday-Friday during office hours. Permits may be issued as paper or electronic records. Applicants receive originals, mail, or facsimile and permit services can expedite processing.
What law enforcement inspects
Law enforcement will check that the permit is must carried and valid before movement. We keep paper and electronic copies in the cab. We also verify OS‑32 insurance so the permit duration never lapses mid‑route.
“Valid permits must obtained and kept available for roadside inspection.”
- We confirm which permit must obtained for each vehicle and vehicle load.
- We list any intermediate stops for food, fuel, and rest on the application.
- We provide a concise packet so law enforcement can verify compliance quickly.
What ODOT and law enforcement expect from drivers and carriers
Before any movement, we confirm licensing, endorsements, and duty-time plans that fit agency windows. Drivers must comply with Federal Motor Carrier Safety Regulations (49 CFR Parts 382–399). We verify CDL class, medical certificates, and necessary endorsements.
Driver licensing, endorsements, and hours-of-service limits
We build duty schedules that respect hours-of-service limits. Short staging, clear rest plans, and documented driver logs reduce risk. We brief drivers on permit conditions and roadside inspections so documents are ready.
Coordination with Ohio State Highway Patrol for rolling roadblocks
ODOT collaborates with the Ohio State Highway Patrol for controlled moves that need lane reversals or low-speed crossings. We request OSHP support when a vehicle load requires managed intersections.
- We confirm CDL and endorsements before scheduling.
- We align staging and escorts within weekday office windows to support monday friday staffing.
- We submit contact rosters and comms channels to law enforcement.
- We certify lighting, markings, and signs so vehicles meet safety visibility standards.
- We monitor in-route execution and contact the department transportation for single trip timing or route changes.
“Clear documentation and ready equipment keep moves predictable and safe.”
Required information when applying: vehicles, loads, and company details
Provide exact company and route facts up front so permit reviewers can act quickly. We collect core carrier data and verify every field before submission. This reduces follow‑up and keeps moves on schedule.
What we gather:
- USDOT number, company address, main phone, and 24/7 contact so the application lists a reliable point of contact.
- Vehicle details: license plate, VIN, make/year, registered weight, and unit number to match enforcement records.
- Load specifics: length, width, height, and front rear overhang plus gross weight and axle spacing for structural checks.
- Exact origin and destination tied to the State Highway System, county names, and every requested route and authorized stop.
Why accuracy matters. Consistent entries across forms help permits issued with fewer questions. We validate axle counts, tire configs, and staging needs. We also attach maps and structure notes to show route viability.
Field | Example / Note | Why we collect it |
---|---|---|
USDOT number | 1234567 | Links carrier to safety records and insurance filings |
Vehicle & VIN | CA 9ABC123 / 1HTMKAAL0KH123456 | Matches plate to unit for roadside verification |
Load dimensions | Length 85′, Width 14’6″, Height 15’2″, front rear overhang 6′ | Determines clearances, escort needs, and permit may require special devices |
Origin / Destination | County: Franklin; Route: SR 315 to State Highway | Defines legal routing and intermediate stops for fuel/rest |
Financial responsibility and damage prevention obligations
Proof of insurance and bond coverage is the first line of defense against costly roadway claims. ODOT requires an OS‑32 endorsement or a surety bond with a minimum of $500,000. Higher amounts may be required for higher‑risk routes.
We coordinate OS‑32 filing with your insurer and the ohio department transportation. The OS‑32 may be submitted by email to hauling.permits@dot.ohio.gov, or by fax or mail. We keep endorsement numbers and effective dates at hand.
Permit duration will not extend beyond the insurance expiration date. We align permit timing to your policy term so coverage never lapses mid‑move.
- We verify minimum liability and recommend higher limits for risky structures or traffic conditions.
- We document vehicle load distribution and securement steps to reduce strain on pavements and bridges.
- We build a damage prevention plan with slow‑approach protocols at known risk locations.
- We keep copies of the OS‑32 with the permit packet for quick inspection.
ODOT holds permit holders responsible for any damage caused by negligent moves. We engage department transportation early when extra protections are needed. Post‑move, we provide reporting templates to address any findings quickly and transparently.
“Accurate insurance and clear procedures keep moves predictable and protect public assets.”
Route planning on I‑80: structures, utilities, and traffic impacts
We map every clearance and structure to prevent surprises during a heavy-haul operation. Early field checks reduce risk. They make permit review and execution smoother.
We pre-survey bridges and under‑clearance points along routes and adjacent state highway segments. Inspecting deck heights and girder spacing lets us verify safe passage for each vehicle load.
We coordinate with ODOT districts and county agencies to plan rolling traffic control, intersection holds, and staging areas. OSHP rolling roadblocks are arranged when needed to protect crews and other vehicles.
Temporary works may include raising overhead lines or the short-term replacement of signs and signals. We secure approvals and schedule minimal closures. Utilities get contacted to add slack or relocate poles as required.
- We simulate swept paths to confirm lane use and shoulder needs for the load.
- We set slow zones near sensitive structures to limit dynamic damage.
- We publish concise route briefs so crews know pinch points and recovery areas for a vehicle load.
We keep the department transportation informed and obtain approvals for temporary measures and their safe replacement after the move. For related timing and curfew guidance, see state-specific curfew rules.
Safety operations: escorts, rolling roadblocks, and communication
We lead coordinated traffic control plans that keep each heavy move predictable and safe. Daylight operations remain standard to maximize visibility and reduce risk.
OSHP and ohio department transportation work together to manage rolling roadblocks and controlled intersections. The state highway patrol or local law enforcement may assume traffic control at critical points. We brief both agencies on timing, speeds, and critical maneuvers before any move.
Height sensing devices and escort protocols
Height Sensing Device means a pole or electromechanical unit mounted on the lead escort. It detects low vertical clearance early so the permitted vehicle can stop safely.
- We assign certified front and rear escorts and fit the lead with a height sensor sized for route clearances.
- We set radio channels, call signs, and check-in points to keep continuous comms among vehicles and crews.
- We train teams to keep safe following distances and maintain sight lines around the vehicle load.
- We brief law enforcement and highway patrol on contingency steps if the height pole contacts overhead features.
- We verify lighting, flags, banners, and pilot car signage before departure.
“Clear roles and tested devices reduce surprises and speed resolution.”
Protocol | Who | When | Outcome |
---|---|---|---|
Lead escort with height sensor | Escort team | Pre-run and during move | Early vertical clearance alerts |
Rolling roadblock coordination | ODOT & state highway patrol | At complex intersections | Managed traffic flow and protected crews |
Radio and check-in plan | Drivers, escorts, dispatch | Every staging point | Continuous situational awareness |
Disabled equipment recovery | Carrier & OSHP liaison | As needed | Rapid tow and off-line staging |
Timing windows: a.m. departures, daylight hours, and overnight staging
Scheduling begins with sunrise rules and practical a.m. departure targets. ODOT defines daylight as one-half hour before sunrise to one-half hour after sunset. District advisories commonly list 7:30 a.m. or 8:15 a.m. as preferred starts.
Why we run moves monday friday in daylight. Daytime starts give better visibility and keep law enforcement and escort resources available. Weekend or night moves extend timelines and raise safety risks. We prefer weekday windows to keep staffing predictable.
Driver limits and overnight parking
We build duty plans that respect hours‑of‑service. Drivers get staged breaks and preapproved overnight stops that fit the vehicle load size.
- We set a.m. departures to meet daylight and escort staffing needs.
- We verify that must obtained permits list intermediate stops and staging details.
- We plan segment length and speed so the load arrives before darkness, considering weight and length limits.
- We reserve parking areas sized for vehicles, escorts, and support trucks.
- We coordinate with ohio state and local partners so contacts are ready at arrival.
- We monitor weather and shift a.m. departure times if visibility or safety falls short.
- We keep permit duration aligned with scheduled moves to avoid validity gaps during staging or delays.
“Early, planned departures simplify enforcement support and reduce risk.”
Real‑world Ohio super load routing practices that inform I‑80 moves
Field advisories describe slow, deliberate progress through tight interchanges. Lane reversals and temporary lane use solve geometry conflicts. We rely on OSHP and ODOT rolling roadblocks for complex ramp moves.
Slow speeds, lane reversals, and temporary lane use
We plan slow travel speeds so a vehicle can clear pinch points without sudden maneuvers. Pilot cars hold safe spacing. Lead escorts monitor vertical clearance and warn of hazards.
Where ramps lack room, crews may run the wrong way on a ramp under controlled conditions. Approvals come from the ohio department and local districts. Temporary sign removal or replacement follows when needed to preserve clearances.
Minimizing community impacts and coordinating around events
We coordinate with each county and local agencies. Moves avoid nights and weekends when possible. We pick preapproved a.m. starts and designated overnight parking to limit neighborhood disruption.
- We schedule rolling traffic control and pilot sequences to protect crews and other drivers.
- We work with utilities to lift lines and arrange safe overhead sign replacement.
- We track pavement and structure conditions to reduce damage and adapt plans when needed.
“Clear public notices and tight timing reduce surprises and keep routes open.”
Mobile/manufactured homes and modular units: special considerations
Crossing county lines with a mobile manufactured home needs visible tax clearance and proof kept inside the unit. Utah Administrative Rule R909‑2‑9 allows moves of mobile and manufactured homes on semi‑trailer lowboys in certain cases. For loads beginning in Utah, carriers must obtain a Tax Commission Movable Structure Tax Clearance/Moving Permit (TC‑138).
We ensure the TC‑138 or equivalent county sticker is affixed to the rear and that proof is carried inside the home for inspection. Ohio and other states differ, so we confirm county tax clearances and display rules before departure.
When a lowboy is appropriate and what to carry
We decide whether a modular, manufactured home, or mobile home should ride a lowboy or a specialized frame carrier. That choice protects structure integrity and meets permit conditions.
- Documentation: TC‑138 or county clearance, route approvals, and tie‑down specs carried inside the home for law enforcement review.
- Load protection: Padding, cribbing, and support to reduce stress at joints and roof eaves.
- Rigging & assessment: Lifting plans and structural checks to avoid damage during load and set‑down.
- Operational limits: Speed caps, weather thresholds, and escort plans matched to unit footprint and sight lines.
- Route checks: Overhead clearances, tight turns, and staging coordinated with site crews to ensure safe unloading.
“Visible tax clearance and complete in‑unit documentation speed inspections and reduce delays.”
Oversize/overweight vehicles and loads crossing state lines on I‑80
Cross-border heavy-haul moves need extra planning to match differing state review windows and escort rules. We start early. That prevents last-minute holds at a border.
Comparative benchmarks: Utah processes extreme moves (over 17’6″ high, 17′ wide, or 300,000 lbs.) Monday–Friday 8 a.m.–5 p.m. and may take up to 14 days to approve. Ohio’s Director issues Special Hauling Permits, so we align filings to both agencies.
How multi‑state coordination affects lead times
Different states set different thresholds and timelines. We track each jurisdiction so permits may be ready before departure.
Our checklist:
- Coordinate permits issued across states so a single trip doesn’t stall at a border.
- Benchmark extreme height or mass thresholds to set realistic lead times.
- Harmonize escort, signage, and lighting rules so vehicles loads stay compliant end‑to‑end.
- Align size weight declarations and structural analyses with each state highway authority.
- Confirm whether permits may include intermediate stops and list them per state.
“Early, harmonized filings prevent border delays and keep convoys moving.”
Challenge | Example | Impact | Our action |
---|---|---|---|
Processing window | Utah: M–F, 8–5; up to 14 days | Longer lead times | File early and track status |
Escort differences | State A needs front/rear escorts; State B adds OSHP support | Extra crews, gear | Match escort specs and certs across states |
Permit duration | Varying valid periods per state | Risk of lapse mid‑route | Plan overlapping permit windows |
Combination vehicles | Different bridge formulas | Reconfiguration needs | Sequence swaps and declare axle groups |
How we streamline your permit application and routing
We make permit filings precise and effective. Our process reduces back-and-forth with reviewers. That saves time and keeps your project on schedule.
Collecting precise length, width, height, and axle groupings
We measure length, width, height, and deck height to the inch. We log axle group spacings for tandem, tri, and quad definitions so weight spreads correctly.
We validate VINs, plate numbers, unit IDs, and contact numbers before submission. Clean data prevents rejected filings.
Optimizing requested routes and intermediate stops for food, fuel, rest
We design routes that limit structure risk and match escort windows. ODOT allows intermediate stops when listed on the permit, so we place fuel and rest points strategically.
- We model combination vehicles to distribute weight and simplify reviews.
- We align trailer choice, bolster height, and tire pressures to fit preferred corridors.
- We produce clear maps and turn-by-turns for crews, escorts, and enforcement.
- We pre-clear staging areas for inspections and equipment checks.
“Complete, consistent applications move faster and cut revisions.”

What to have in the cab on the day of the move
Bring a concise document pack to the cab so crews and officials verify compliance quickly. We keep paper and electronic files ready. This avoids delays during roadside checks.
Permit documents, insurance filings, contact sheet, and traffic control plan
Permits must carried and shown on demand. ODOT permits may be paper or electronic, but the signed packet should be accessible in the cab before departure.
- Signed permit packet: paper and digital copies so documents are must carried and quick to present.
- OS‑32 insurance endorsement: include the policy number and effective dates. Permit duration cannot exceed insurance expiration.
- Contact sheet: dispatch, escorts, OSHP and ohio department points, wrecker service, and utility liaisons with address notes for each contact.
- Traffic control plan: staging notes and check points so law enforcement can verify conditions instantly.
- Dimension & weight summary: length, width, height, gross weight, axle spacings, and front rear overhang details for quick structural checks.
- Route maps & contingencies: strip maps, detour options, and known closure workarounds.
- Permit may conditions: listed intermediate stops, curfew windows, and required escort devices so crews follow the permit exactly.
- Pre‑trip checklists: driver and supervisor signatures proving inspections were completed.
- Binder & digital folder: organized for fast retrieval during roadside inspections.
- Seals and placards: verify they match the permit so the vehicle load passes inspection without delay.
“Carry clear, complete records in the cab so reviews go smoothly and moves stay on schedule.”
We train drivers to produce the packet immediately when requested by law enforcement. That simple habit keeps inspections brief and operations predictable.
