How to Ship Oversize & Overweight Loads in Alberta

Alberta figures verified against Government of Alberta (alberta.ca) · 2026-09· Last reviewed September 2026

Freight is legal in Alberta until it outgrows the province's size and weight envelope; from that point, movement runs on permits, marked vehicles, and rules about when and where the load may travel.

Alberta oversize thresholds

Width: over 8.5 ft needs a permit
Height: over 13.6 ft needs a permit
Weight: Gross and axle limits follow each province's weight tables; interprovincial MoU vehicles run to 62,500 kg on compliant configurations.
Length: 16.2 m (53 ft) semitrailers are standard under the national MoU; overall combination limits are provincial.

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 Alberta

Not every permitted load is the same size of problem. Alberta tiers them:

Routine permitted

The everyday oversize move: permit, marking, escorts by band.

Route-surveyed

Alberta's permits attach conditions per load and route; the province also maintains a designated High Load Corridor network built for over-height moves, which dispatch routes onto when height demands it.

Superload

The largest class: engineering review, possible police escorts, and a schedule set by the authority.

Permits in Alberta: who issues them

Oversize and overweight permits are issued by the Central Permit Office, Alberta Transportation and Economic Corridors, through TRAVIS Web; the permit office answers at 1-800-662-7138. Your carrier or its permit service deals with the office directly, and the cost is in your quote when your dimensions require it.

•Permits are for loads that are non-divisible, impractical to divide, or uneconomical to move at legal size, matching the continental divisibility principle.
•Single-trip overweight permits can have weights amended down after a government scale weighing without re-application, under the province's amended-weights procedure.
•Alternative-fuel trucks (electric, CNG, LNG, hydrogen) can permit up to 1,000 kg of extra steer/drive-axle weight to offset heavier powertrains; gross limits stay unchanged.
•Municipal roads need municipal approval on top of provincial permits.

The escalation ladder: from legal load to the move nobody makes

As dimensions grow, requirements stack in the same order everywhere; Alberta 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 province'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 province'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

At the province's superload thresholds: engineering review, route surveys, police escorts, sometimes rolling road closures and utility crews lifting lines ahead of the convoy. Typical: a 16 ft wide transformer or a bridge girder.

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.

Escort counts come as permit conditions; Alberta publishes a dedicated Escort Vehicle Operator's handbook, and front escorts run 300 to 1,000 m ahead of the load with dimensional signs and flashing lights.

Examples are typical industry scenarios for scale, not Alberta determinations; the permit for your move states the binding requirements.

Permits, escorts, and travel windows in practice

The mechanics in Alberta follow the continental pattern: a single-trip permit describing the load and its route, escort vehicles from the province's width and length bands upward, marked banners and flags on the load, and travel windows that favour daylight and quiet roads. The details are Alberta's own, and they are applied to your move at dispatch. For how each piece works everywhere, see the guides on pilot cars & escorts, permits, travel windows and spring frost laws, which apply in Alberta's climate.

Alberta runs a formal Seasonal Axle Weight Program: frozen winter ground earns higher allowable weights, and spring thaw brings road bans that cut axle limits on posted roads until conditions recover. Current restrictions publish on the province's road bans service, and overweight permits follow them.

Permits in Alberta are issued by the Central Permit Office, Alberta Transportation and Economic Corridors; your carrier or its permit service deals with the office directly.

Common questions

When does a load count as oversize in Alberta?▾

In Alberta, a load is oversize once it exceeds 8.5 ft in width, 13.6 ft in height; beyond those figures a permit is required before it moves.

Do I need to get the Alberta permit myself?▾

No. Movement permits attach to the carrier and vehicle, not to the shipper. When your dimensions require a Alberta 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 Alberta?▾

Escorts are triggered by width, length, and height bands that Alberta 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 Alberta?▾

Daylight travel is the working default for oversize loads across North America, with curfews in major urban areas and restrictions on statutory holidays. Alberta'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.
