How to Ship Oversize & Overweight Loads in Kentucky
Kentucky figures verified against Kentucky Transportation Cabinet (drive.ky.gov) · 2026-09· Last reviewed September 2026
Freight is legal in Kentucky until it outgrows the state's size and weight envelope; from that point, movement runs on permits, marked vehicles, and rules about when and where the load may travel.
Kentucky 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 Kentucky
Not every permitted load is the same size of problem. Kentucky tiers them:
Routine permitted
Permits issue in the normal course up to about 13.9 ft wide, 13 ft 6 in tall, 120 ft long.
Route-surveyed
Kentucky's workhorse annual class carries non-divisible loads just under 14 ft wide, to 120 ft long and 160,000 lb; a proposed-route survey form supports the bigger applications.
Superload
Past the annual class, moves clear individually with route survey; overweight permits presuppose a declared gross of at least 80,000 lb, i.e. the permit begins where legal weight ends.
Permits in Kentucky: who issues them
Oversize and overweight permits are issued by the Kentucky Transportation Cabinet, Division of Motor Carriers (DRIVE). Your carrier or its permit service deals with the office directly, and the cost is in your quote when your dimensions require it.
The escalation ladder: from legal load to the move nobody makes
As dimensions grow, requirements stack in the same order everywhere; Kentucky 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 the state's first width band (commonly in the 12 ft range): 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
Past the annual class, moves clear individually with route survey; overweight permits presuppose a declared gross of at least 80,000 lb, i.e. the permit begins where legal weight ends. 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.
Kentucky writes escort practice in detail: escorts hold roughly 300 ft on open highway (closer or farther as safety demands), a rear escort joins whenever overhang passes 10 ft, and the oversize banner spec (size, letter height, stroke) is codified to the inch.
Examples are typical industry scenarios for scale, not Kentucky determinations; the permit for your move states the binding requirements.
Permits, escorts, and travel windows in practice
Above the envelope, Kentucky issues single-trip permits against your exact declared dimensions, often with a prescribed route, and escort vehicles attach as width and length grow: one pilot car at the first band, two beyond it, and a height-pole car for the tallest loads. Daylight travel is the working default, with tighter windows in cities and on holidays. For how each piece works everywhere, see the guides on pilot cars & escorts, permits, travel windows.

Common questions
When does a load count as oversize in Kentucky?▾
In Kentucky, 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 Kentucky permit myself?▾
No. Movement permits attach to the carrier and vehicle, not to the shipper. When your dimensions require a Kentucky 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 Kentucky?▾
Escorts are triggered by width, length, and height bands that Kentucky sets itself, and the count changes with road type. Your quote prices escort bands from your declared dimensions, and the permit for the move states the binding requirement.
Can oversize loads travel at night or on holidays in Kentucky?▾
Daylight travel is the working default for oversize loads across North America, with curfews in major urban areas and restrictions on statutory holidays. Kentucky'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.
