What We Handle

Every permit your load touches, in one place.

From a single oversize move to a standing fleet program, our permit desk and routing engineers cover the full range of OS/OW compliance work.

01

Oversize Permits

Permitting for loads exceeding legal length, width, or height, with state-specific routing built in from the start.

02

Overweight Permits

Gross and axle-weight compliance checked against every state DOT's bridge formula before a permit ever gets filed.

03

Superload Permits

Engineering-grade review for loads that can't be broken down or reduced, including bridge and structural coordination.

04

Route Engineering & Surveying

Turn-by-turn routes checked for clearance, weight limits, and local restrictions — not just the shortest line on a map.

05

Pilot Car & Escort Coordination

Certified escort vehicles arranged and scheduled wherever a state's regulations call for one.

06

Trip & Fuel Permits

Temporary trip permits and IFTA fuel permits handled alongside your OS/OW paperwork so nothing gets missed.

How It Works

From load details to legal on the road.

A straight path with an engineer checking every mile of it.

01

Submit load details

Dimensions, weight, axle configuration, origin and destination — through our portal or your permit desk contact.

02

Engineering review

We check bridge formulas, clearances, and axle limits state by state before anything is filed.

03

Permits issued

Approved permits and route packets land in your hands before wheels are scheduled to roll.

04

On-road support

Route change mid-haul, or a question from an inspector? Our desk is staffed around the clock.

Why OBN

Software handles the paperwork. Engineers handle the judgment calls.

PE

Engineer-reviewed, not just filed

Every route gets checked by someone who understands bridge formulas and axle math — not just permit form fields.

</>

Purpose-built routing software

Our in-house platform cross-references clearance and weight-limit data so nothing gets missed between states.

DOT

Direct lines into state permit offices

Established relationships with DOT, DMV, and DPS permit desks keep applications moving instead of sitting in a queue.

24

A desk that's actually staffed

Route changes and inspector questions don't wait for business hours, so neither do we.

Clearance Check

Bridge & overhead clearance, verified before you drive it.

14'-2" CLR LOAD PROFILE

Every structure along the route is checked against your load's actual height, width, and weight before a permit is issued.

On The Road

The loads we permit, moving.

A real haul from the field — the kind of load our routes and permits are built around.

From Carriers We Work With

Fewer surprises on the road.

We stopped finding out about clearance problems from our drivers and started finding out from OBN, before the truck ever left the yard.

FLEET MANAGER, MERIDIAN HEAVY HAUL

Superload jobs used to mean days of back-and-forth with state engineers. OBN's team handles that coordination directly now.

OPERATIONS LEAD, GRANITE STATE RIGGING

Having a permit desk that answers at 2 a.m. when a route gets closed has saved more loads than I can count.

Common Questions

What carriers usually ask us first.

Requirements vary by state, but as a general rule a load needs a permit once it goes past standard legal limits — commonly around 8'6" wide, 13'6" tall, 53' long for a trailer, or 80,000 lbs gross. Individual axle or axle-group weight limits can trigger a permit even when the gross weight is legal.

Generally yes — each state issues its own permit and sets its own rules for travel hours, escort requirements, and allowable routes. We handle the full multi-state sequence so you're not filing separately with each one.

It depends on the state and how far your load exceeds standard dimensions. Some states set fixed width or length thresholds; others leave it to the permitting agency's discretion. We confirm escort requirements for your specific route before you're on the road.

Turnaround depends on the state agency and the complexity of the load — some routine permits clear in under an hour, while superloads requiring bridge analysis can take longer. We'll give you a realistic estimate once we see your load details.

No — permitted routes are fixed, aside from stops at designated weigh stations or truck stops along the way. If conditions change mid-haul, contact our desk and we'll get an amended route or permit in place.

Tell us about the load. We'll tell you what it takes to move it legally.

Reach the permit desk directly, or send load details through the form and an engineer will follow up with a quote and timeline.
