Lowboy Trucking Rates: What to Expect for Heavy Haul Transport
Lowboy trucking rates are significantly higher than standard flatbed or dry van rates because of the specialized equipment, driver expertise, permit costs, and higher insurance associated with heavy haul transport. In 2026, standard legal lowboy loads typically run $3.50 to $8.00 per mile, while oversize and overweight loads with permits and escorts can cost $5.00 to $15.00 or more per mile. This guide breaks down every pricing factor so you know what to expect when shipping heavy equipment.

Lowboy Rate Ranges by Load Type (2026)
Lowboy trucking rates vary dramatically based on whether the load is legal-size (no permits needed) or oversize/overweight (requiring permits and potentially escorts). Here are current market ranges:
| Load Type | Per-Mile Rate | 500-Mile Example | Includes |
|---|---|---|---|
| Standard legal load | $3.50-5.00 | $1,750-2,500 | Transport only, no permits needed |
| Oversize (width/height) | $5.00-8.00 | $2,500-4,000 | Oversize permits, possible escort |
| Overweight (80K-120K GVW) | $6.00-10.00 | $3,000-5,000 | Overweight permits, route restrictions |
| Oversize + overweight | $8.00-15.00+ | $4,000-7,500+ | Multiple permits, escorts, route surveys |
| Superload (150K+ GVW) | Custom quote | $10,000-50,000+ | Engineering analysis, police escorts, bridge surveys |
Local hauls (under 100 miles) are typically quoted as flat rates rather than per-mile. Local lowboy moves run $300 to $800 for standard legal loads and $800 to $2,500+ for oversize loads. The minimum charge for dispatching a lowboy — regardless of distance — is usually $300 to $500 because of the fixed costs of driver time, fuel, and equipment.
These rates represent transport costs only. Additional services like crane loading ($500 to $3,000+), rigging ($200 to $1,000), and disassembly/reassembly (varies widely) are typically billed separately.
What Determines Lowboy Trucking Rates
Lowboy rates are not standardized — every load is quoted individually based on multiple factors. Understanding what drives pricing helps you evaluate quotes and negotiate effectively:
Load Weight
Heavier loads require more axles, stronger trailers, and potentially overweight permits. A 40,000-pound load on a 2-axle lowboy costs significantly less than an 80,000-pound load requiring a multi-axle trailer and overweight permits. See our weight capacity guide.
Load Dimensions
Width, height, and length all affect pricing. Loads wider than 8'6", taller than 13'6", or longer than the trailer deck require oversize permits. Each oversized dimension adds permit costs, potential route detours, and may require escort vehicles.
Distance
Per-mile rates typically decrease on longer hauls because fixed costs (loading, permits, deadhead) are spread across more miles. A 200-mile move might cost $5.00/mile while a 1,000-mile move might cost $3.50/mile for the same equipment.
Permit Requirements
Each state requires its own oversize or overweight permit. A 5-state move might cost $500 to $3,000 in permits alone. Some states require route surveys for very heavy loads, adding engineering costs.
Escort Vehicles (Pilot Cars)
Many states require one or two escort vehicles for loads exceeding specific width or weight thresholds. Escort costs run $500 to $1,500 per day per vehicle. A 3-day cross-country move with two escorts can add $3,000 to $9,000 to the total cost.
Loading Method
If crane loading is required (no RGN trailer or non-mobile equipment), crane rental adds $500 to $3,000+ per location. This is typically billed separately from the transport rate but is a real cost of the move.
Permit & Escort Cost Breakdown
Permit and escort costs are often the biggest surprise in heavy haul pricing. Here is what to budget:
| Cost Item | Typical Range | Notes |
|---|---|---|
| Oversize permit (per state) | $15-200 | Single-trip permits for width/height/length |
| Overweight permit (per state) | $50-500+ | Increases with weight; 100K+ GVW much higher |
| Superload permit (per state) | $500-5,000+ | 150K+ GVW; includes engineering analysis |
| Pilot car (per day) | $500-1,500 | Some loads require 2 pilot cars (front + rear) |
| Police escort (if required) | $50-200/hour | Required by some states for superloads |
| Route survey (if required) | $500-3,000 | Bridge weight analysis for very heavy loads |
| Permit service fee | $50-150 per state | If using a permit service to file on your behalf |
Permits Can Double Your Transport Cost
Distance & Per-Mile Economics
Lowboy rates follow a declining per-mile curve as distance increases. This is because certain costs are fixed regardless of distance:
- Loading and unloading time — Same whether the haul is 50 miles or 500 miles
- Permit acquisition — Same paperwork and fees for short and long hauls within the same state
- Deadhead to the pickup — The carrier must drive to the loading site, often empty
- Equipment wear — Loading stress on the trailer is the same regardless of distance
For this reason, short hauls (under 100 miles) typically use flat rates ($300-800+) rather than per-mile pricing. The per-mile rate is highest for 100-300 mile hauls ($4.00-8.00/mile) and decreases for longer hauls ($3.00-5.00/mile at 500+ miles). Very long hauls (1,000+ miles) may dip below $3.50/mile for standard legal loads.
Seasonal Rate Fluctuations
Lowboy rates follow construction industry seasonality more than general freight market trends:
| Season | Demand Level | Rate Impact | Notes |
|---|---|---|---|
| Spring (Mar-May) | Highest | +15-25% | Construction season starts; equipment moves to job sites |
| Summer (Jun-Aug) | High | +10-20% | Peak construction; steady high demand |
| Fall (Sep-Nov) | Moderate-High | +5-15% | Construction winding down; equipment returning from sites |
| Winter (Dec-Feb) | Lowest | Baseline | Reduced construction; best time to move equipment |

How to Get Competitive Lowboy Quotes
Getting accurate, competitive quotes for lowboy transport requires providing detailed information upfront. Here is what to include in every quote request:
Exact equipment weight — Not “about 40,000 pounds” but the actual operating weight including any attachments. Carriers price based on weight; inaccurate weight leads to re-quotes or surprise charges.
Exact dimensions — Height, width, and length of the equipment in transport configuration (boom lowered, blade down, tracks retracted). Include the highest point and widest point.
Pickup and delivery addresses — Full addresses, not just cities. Site conditions matter — is it paved or dirt? Is there room for a lowboy to maneuver? Is crane access available?
Pickup date flexibility — A flexible pickup window (e.g., “anytime next week”) typically yields better rates than “must pick up tomorrow.” Carriers can plan more efficiently with lead time.
Ask for all-in pricing — Request quotes that include transport, permits, escorts, and fuel surcharge. An “all-in” quote prevents surprise add-ons after booking.
Hidden Costs to Watch For
Fuel surcharge — Some carriers quote a base rate and add fuel surcharge separately. This can add $0.25 to $0.75 per mile. Always ask if fuel surcharge is included in the quoted rate.
Deadhead charges — If the carrier must drive a long distance empty to reach your pickup location, they may charge for deadhead miles at $1.50 to $3.00 per mile. Ask about deadhead policies upfront.
Detention charges — If loading or unloading takes longer than 2 hours (typical free time), carriers charge detention at $50 to $100+ per hour. Have equipment ready to load when the carrier arrives.
Weight re-quote — If the actual equipment weight at the scale differs from the quoted weight, the carrier may re-price the load. Accurate weight information prevents this.
Storage fees — If the delivery site is not ready and the carrier must hold the load, storage fees of $100 to $300 per day may apply. Coordinate delivery timing carefully.
Rate Tips for Lowboy Carriers
If you are a carrier operating a lowboy, here is how to price your loads competitively while protecting your margins:
Know your cost per mile — Heavy haul costs more to operate than standard flatbed. Factor in higher insurance, tire wear, fuel consumption with heavy loads, and permit costs. Your cost per mile is likely $2.50 to $4.00 before any profit margin.
Include all costs in your quote — Permits, escorts, deadhead to the pickup, fuel surcharge, and loading time should all be factored into your rate. Do not eat these costs hoping for volume.
Reduce deadhead to increase margins — The biggest profit killer for lowboy carriers is driving empty. Plan backhaul loads, build relationships with equipment dealers and construction companies along your routes, and use load boards to minimize empty miles.
Build direct shipper relationships — Construction companies and equipment rental firms that move equipment regularly are the most valuable customers for lowboy carriers. Direct relationships mean higher rates and more consistent loads compared to broker freight.
