How to Ship Oversize & Overweight Loads in Louisiana
Louisiana figures verified against Louisiana DOTD (dotd.la.gov) · 2026-09· Last reviewed September 2026
Moving something big through Louisiana is a solved problem: the state publishes the envelope, sells the permission to exceed it, and expects the load marked, escorted, and timed by its rules.
Louisiana oversize thresholds
- Width
- over 8.5 ft needs a permit
- Height
- over 13.5 ft needs a permit
- Gross weight
- over 80,000 lb needs a permit
- Length
- A 53 ft semitrailer is the standard; overall combination limits are state-set.
- Axles (interstate standard)
- 20,000 lb single · 34,000 lb tandem
Does your load need a permit here?
Skip the reading: enter your real dimensions and weight in the quote engine and it applies the thresholds of every jurisdiction on your actual route, prices permits and escorts where your load crosses the bands, and locks the price for 30 days.

From routine permit to superload in Louisiana
Not every permitted load is the same size of problem. Louisiana tiers them:
Routine permitted
Permits issue in the normal course up to about 12 ft wide, 14 ft 4 in tall, 90 ft long.
Route-surveyed
Louisiana's routine permit window runs to 12 ft wide, 14 ft 4 in high, and 90 ft long (with generous 25 ft overhang allowances); applications past 16 ft wide, 15 ft 6 in high, 125 ft long, or 232,000 lb go to a permit specialist for individual review.
Superload
The biggest Louisiana moves layer supervision: past 18 ft of width a DOTD district representative must be present or authorize the move on the permit before police escorts will run it, on top of the specialist review tier.
Permits in Louisiana: who issues them
Oversize and overweight permits are issued by the Louisiana DOTD Truck Permit Section. Your carrier or its permit service deals with the office directly, and the cost is in your quote when your dimensions require it.
- •Permit shapes include monthly and semi-annual terms alongside single-trip and annual, an unusually flexible menu.
The escalation ladder: from legal load to the move nobody makes
As dimensions grow, requirements stack in the same order everywhere; Louisiana sets the exact trigger points.
1 · Legal load
Inside the envelope above: no permit, no escorts, travels any lawful hour. Typical: a 20 ft container on a flatbed, a pickup on a hotshot, pallets in a van.
2 · Permitted, no escort
Over the envelope but inside the state's first escort band: permit, banner and flags, daylight-type windows. Typical: a 10 ft wide skid-steer-and-attachments load on a step deck.
3 · One escort
From about 12 ft of width in Louisiana: a certified pilot car leads on two-lane roads or follows on divided highways. Typical: a 12 ft wide dozer on an RGN.
4 · Two escorts / pole car
Wider still, and on two-lane routes: escorts front AND rear. Very tall loads add a height-pole car that proves every wire and bridge before the load reaches it. Typical: a 14 ft wide, 15 ft tall excavator on a lowboy.
5 · Police escort / superload
The biggest Louisiana moves layer supervision: past 18 ft of width a DOTD district representative must be present or authorize the move on the permit before police escorts will run it, on top of the specialist review tier. At this scale expect route surveys, possible rolling closures, and utility crews lifting lines ahead of the convoy.
6 · Cannot move as one piece
Past what roads, bridges, and wires physically accept, or whenever the load is DIVISIBLE: authorities expect it reduced, not permitted. Booms come off, counterweights ship separately, buildings split into sections; the truly non-reducible goes to engineered transport, rail, or barge for part of the journey.
Certified escorts join from 12 ft wide or 90 ft long, carrying state-set insurance minimums; the state has also allowed qualified civilian escorts in place of police on state highways under a standing announcement.
Examples are typical industry scenarios for scale, not Louisiana determinations; the permit for your move states the binding requirements.
Permits, escorts, and travel windows in practice
The mechanics in Louisiana follow the continental pattern: a single-trip permit describing the load and its route, escort vehicles from the state's width and length bands upward, marked banners and flags on the load, and travel windows that favour daylight and quiet roads. The details are Louisiana's own, and they are applied to your move at dispatch. For how each piece works everywhere, see the guides on pilot cars & escorts, permits, travel windows.
Permits in Louisiana are issued by the Louisiana DOTD Truck Permit Section; your carrier or its permit service deals with the office directly.
Common questions
When does a load count as oversize in Louisiana?▾
In Louisiana, a load is oversize once it exceeds 8.5 ft in width, 13.5 ft in height; beyond those figures a permit is required before it moves.
Do I need to get the Louisiana permit myself?▾
No. Movement permits attach to the carrier and vehicle, not to the shipper. When your dimensions require a Louisiana permit, the carrier or its permit service obtains it, the cost is priced into your quote, and the paperwork rides in the cab.
Will my load need a pilot car in Louisiana?▾
Escort requirements in Louisiana begin around 12 ft of width; road type changes the count, and the permit states the final requirement.
Can oversize loads travel at night or on holidays in Louisiana?▾
Daylight travel is the working default for oversize loads across North America, with curfews in major urban areas and restrictions on statutory holidays. Louisiana's current windows are applied to your route during dispatch planning, and your pickup and delivery estimates already reflect them.

This guide is provided free, for general information, so shippers can see how oversize and overweight moves work. It is not legal advice and not a permit determination. Limits, escort bands, fees, and seasonal restrictions change regularly; before relying on any figure, verify it with the jurisdiction's transportation department or permit office, or a licensed permit service. When you book with LoadLoom, our dispatch desk and your assigned carrier confirm the current rules for your exact load and route; that confirmation, not this page, governs your shipment.
