About These Guides
Heavy haul trucking involves a layer of complexity that most freight shipments never encounter — state-by-state permits, pilot car regulations, bridge weight analyses, utility line lifts, and specialized trailer selection. Shippers new to oversize freight often don't know what questions to ask, and experienced shippers still run into state-specific rules that catch them off guard.
R&RM LLC has been moving oversized and overweight loads since 2011, serving construction companies, utilities, mining operations, manufacturers, and agriculture across all 48 continental states. These guides draw directly on that experience to give you practical, actionable information — whether you are planning your first oversize move or troubleshooting a permit problem on a job that starts next week.
Every guide follows the same principle: accurate information, no fluff, and a clear connection to how it affects your shipment. We do not fabricate statistics or overstate our authority. Where regulations are published by state DOTs and federal agencies, we link directly to the source so you can verify everything yourself.

Read Guide →What Is Heavy Haul Trucking?
Heavy haul trucking refers to the transport of loads that exceed standard legal weight or dimension limits for highway travel. In the United States, a standard flatbed load is legal up to 80,000 pounds gross vehicle weight, 8 feet 6 inches wide, 13 feet 6 inches tall, and 53 feet long. Anything beyond those limits enters heavy haul territory and requires special permits, often specialized trailers, and sometimes police or private pilot car escorts.
Common heavy haul loads include excavators, cranes, power transformers, bulldozers, and mining equipment. The industries that rely most heavily on heavy haul transport include construction, utilities, oil and gas, mining, and agriculture.
How Oversize Permits Work
When a load exceeds legal limits, the carrier must obtain a permit from every state the load passes through — and sometimes from individual counties or cities as well. Permits specify the route, the travel windows (some states restrict oversize movement to daylight hours or prohibit it on holidays), the trailer configuration, and the escort requirements.
Permit fees vary by state and by how far the load exceeds legal limits. A straightforward single-state permit for a slightly overwidth load may cost under $100. A multi-state corridor permit for a 500,000-pound transformer with full escort requirements can run $5,000 or more in combined fees, plus the cost of pilot cars and police escorts. Our permit services team handles all permit applications so shippers do not have to navigate each state's system individually.
The Role of Pilot Cars in Heavy Haul
Pilot cars — also called escort vehicles or flag cars — travel ahead of or behind an oversize load to warn oncoming traffic, help the driver navigate tight turns, and in some cases operate height poles to ensure clearance under bridges and utility lines. Most states require at least one pilot car when a load exceeds 14 feet in width or 14 feet 6 inches in height. Loads that are wider than 16 feet typically require two pilot cars — one in front and one behind — and may also require a law enforcement escort.
Pilot car requirements are set by each state independently. A load moving from Georgia through Tennessee, Kentucky, and into Ohio encounters four different sets of escort rules. Our dispatchers are familiar with the escort requirements along the corridors we travel most frequently, and we coordinate all escort logistics as part of the move.
Choosing a Heavy Haul Carrier
Not every trucking company is equipped to handle oversize and overweight loads. Heavy haul requires specialized equipment — RGN trailers, multi-axle lowboys, and in some cases hydraulic platform trailers — as well as experience with the permit process and a network of reliable escort vehicles.
When evaluating a heavy haul carrier, shippers should ask:
- Does the carrier have experience with this specific type of load?
- Who handles the permit process — the carrier or a third party?
- What is the carrier's claims process if equipment is damaged in transit?
- Can the carrier provide references for similar moves?
- Does the carrier have 24/7 dispatch contact for in-transit issues?
R&RM LLC — R&RM LLC, based in Cumming, Georgia — has been answering those questions affirmatively since 2011. We handle the full move: permit acquisition, trailer selection, escort coordination, and delivery confirmation. Learn more about R&RM LLC or contact us at (404) 987-6225 to discuss your next oversize shipment.
Quick Reference: Common Heavy Haul Questions
- What weight is considered heavy haul? — Loads over 80,000 pounds gross vehicle weight, or any combination of weight, width, height, or length that exceeds legal highway limits, require oversize or overweight permits.
- How long does it take to get permits? — Routine permits in most states process in 24–72 hours. Complex multi-state moves for very heavy or wide loads may take a week or more. Emergency permits are available from some states for critical utility and infrastructure loads.
- Do I need a pilot car? — Generally yes, once a load exceeds 14 feet in width or 14 feet 6 inches in height. State rules vary; some require escorts at 12 feet wide. We determine escort requirements as part of the permit process.
- Can heavy haul move on weekends and holidays? — Most states restrict oversize movement to daylight hours on weekdays. Many states prohibit oversize travel on Sundays, federal holidays, and during certain holiday weekends (Memorial Day, Labor Day, Thanksgiving). We factor these windows into your delivery timeline.
- How far in advance should I book? — For standard loads, 3–5 business days is usually enough time to arrange permits and equipment. For very large or complex moves — especially transformer hauls or loads over 200,000 pounds — 2–4 weeks of lead time is recommended.
