Arkansas Oversize Permits: Types, Costs, and Road Rules

Arkansas oversize permits are issued by the Arkansas Department of Transportation (ARDOT) and are required before any commercial vehicle or non-divisible load that exceeds the state’s standard size or weight limits travels on a state highway. The base permit fee is $17, with additional charges that scale by the amount of excess weight and the distance you plan to haul it. Get the application in before you move, because operating without a permit is a misdemeanor and overweight violations carry per-pound penalties on top of the criminal fine.¹

When You Need a Permit

A special permit is required any time your vehicle or loaded configuration exceeds one of these standard maximums:

Width over 102 inches (8 feet, 6 inches), excluding approved safety devices.²
Height over 13 feet, 6 inches, loaded or unloaded.³
Semi-trailer longer than 53 feet, 6 inches. If the trailer is over that length but the overall combination stays under 60 feet, no length permit is required.⁴
Gross vehicle weight over 80,000 pounds on five or more axles.
Single axle weight over 20,000 pounds.
Tandem axle weight over 34,000 pounds.⁵

Hit any one of those numbers and you need a permit before the wheels turn.

The Load Has to Be Non-Divisible

ARDOT will only permit cargo that cannot readily be taken apart, separated, or otherwise reduced in size or weight. If a shipment can be broken into smaller legal-weight loads, the state will deny the application. Multi-unit or reducible overloads are specifically prohibited from receiving a special permit.¹ Stacking several smaller items on one trailer and calling it an overweight move will not qualify.

Which Permit to Choose

Single-Trip Permit

A single-trip permit covers one movement from origin to destination and is valid for six consecutive days from issuance. That window gives some room for weather or scheduling slippage.⁶ The permit locks you to a specific approved route. Any deviation voids the permit and is treated as an unpermitted movement.⁵

Annual Permit

Carriers that regularly move moderately oversize loads can apply for an annual permit. It is vehicle-specific and valid for twelve consecutive months. Annual permits carry stricter size and weight caps than single-trip permits, so loads at the upper end of what’s permittable will still need single-trip authorizations.

Multi-State Envelope Permit

If a non-divisible load is crossing two or more states within the Southeastern Association of State Highway and Transportation Officials (SASHTO) region, Arkansas participates in the Multi-State Envelope Permit program. A single authorization covers the move across all participating states, so you don’t have to pull a separate permit from each one.⁶

What It Costs

Every special permit carries a $17 base fee. For oversize-only loads that are within legal weight, that $17 is the whole charge. For overweight loads, additional per-ton charges apply based on travel distance:⁵

Up to 100 miles: $8 per excess ton
101–150 miles: $10 per excess ton
151–200 miles: $12 per excess ton
201–250 miles: $14 per excess ton
Over 250 miles: $16 per excess ton

Loads with a gross weight of 180,000 pounds or more pay an additional surcharge of up to $500 on top of the base fee and weight charges.

How to Apply

Applications can be submitted in person, by phone, in writing, or through the ARDOT online permitting system (ARPARS), which is available around the clock for certain envelope vehicle permits. Payment can be made by bonded account, major credit card, check, or cash.⁶

You will need to provide:

Applicant name and address.
Year, make, model, full VIN, license plate number, and state of registration for both the tractor and trailer.
Total number of axles and the spacing between them.
Description of what you’re hauling, along with the serial number on the load itself.
Gross weight, steering axle weight and rating, and the weight on each individual axle.
Maximum width, length, height, and front overhang of the loaded configuration.
Origin and destination inside Arkansas, the specific highway numbers you need to travel, and your intended dates of movement.
The number of escort vehicles that will accompany the load.⁶

The Permit Section builds the route by weighing traffic volume, highway width, and the structural capacity of every bridge between origin and destination. Safety for other drivers takes priority, which can mean a longer route than you’d pick on your own.⁵ Super-heavy or extraordinarily large loads may trigger engineering examinations of bridges along the route, and ARDOT doesn’t publish a timeline for those reviews. Submit well in advance when hauling extreme loads.⁶

Rules Once You’re on the Road

The approved permit document has to be in the vehicle at all times and available for inspection.

Travel Hours

Permitted oversize loads can only travel during daylight hours as defined by the National Oceanic and Atmospheric Administration’s Weather Service, not a fixed clock time.⁷ The travel window shortens in winter and widens in summer. Arkansas does not impose blanket holiday travel restrictions on oversize loads, though an individual permit may include its own conditions.

Signs and Flags

Any vehicle exceeding legal width, height, or length must display “OVERSIZE LOAD” signs on both the front and rear. The signs need a yellow background with black letters at least 10 inches tall with a 2-inch stroke, and must be made of durable material. Red or fluorescent orange flags, 18 inches square, go on all four corners of the load.⁶

Escort Vehicles

Escorts kick in once the load crosses certain width or length thresholds, and the setup depends on the road type.

For over-width loads (excluding manufactured homes):

Over 12 feet but not more than 14 feet wide on non-divided highways: one escort traveling in front of the permitted vehicle.
Over 14 feet wide on controlled-access or divided highways with four or more lanes: one escort traveling 200 feet behind.
Over 14 feet wide on all other highways: two escorts, one in front and one behind.⁶

For over-length loads:

100 feet or longer on interstates and divided highways: one escort following the load.
100 feet or longer on all other highways: one escort leading the load.

Each escort vehicle carries its own “OVERSIZE LOAD” signs and mounts two solid red 18-inch square flags on top. Escorts need liability insurance with minimum coverage of $100,000 per injury, $300,000 per accident, and $25,000 for property damage, or a $325,000 combined single limit.⁶

What a Violation Costs

Moving an oversize or overweight vehicle without a permit, or breaking the terms of one, is a misdemeanor. Both the driver and anyone at the company who authorized the move can be held liable. Criminal fines rise with repeat offenses in the same calendar year:

First conviction: up to $100
Second conviction within one year: up to $200
Third and later convictions within one year: up to $500⁸

Overweight violations carry per-pound civil penalties that stack on top of the criminal fine:

Up to 1,000 lbs. over: $10 to $20
1,001–2,000 lbs. over: 1¢ to 3¢ per pound of excess weight
2,001–3,000 lbs. over: 2¢ to 4¢ per pound
3,001–4,000 lbs. over: 3¢ to 5¢ per pound
4,001–10,000 lbs. over: 4¢ to 6¢ per pound
Over 10,000 lbs.: 8¢ to 10¢ per pound for a first offense, 13¢ to 15¢ per pound for a second, and 18¢ to 20¢ per pound for a third offense in the same calendar year⁸

A truck caught 15,000 pounds overweight on a first offense faces $1,200 to $1,500 in per-pound penalties on top of the criminal fine. A second offense at the same overweight runs roughly $1,950 to $2,250. ARDOT can also void a permit for route deviations or other violations, and a pattern of permit violations gives the agency grounds to deny future applications.⁵
