An oversize load in New Brunswick generally needs one or more pilot vehicles (also called pilot trucks or escort vehicles) once its width, length, height, or weight pushes past what the province treats as normal highway traffic. The exact triggers, escort count, and any high-pole or police requirement are set on your New Brunswick oversize/overweight permit — not by a single fixed rule. The safest move is always to confirm the current escort requirement with the permit office before you roll, because the permit is the controlling document.
Who issues the permit in New Brunswick
Oversize and overweight permits in New Brunswick are issued by the New Brunswick Department of Transportation and Infrastructure (DTI). DTI evaluates the dimensions and weight of your load, the route you intend to take, and the conditions along that route, then writes the permit conditions accordingly — including how many pilot vehicles you need and where they sit relative to the load. Because Canada is metric, your application and permit describe the load in metres and in kilograms or tonnes, not feet and pounds. If you are running an over-dimensional load that crosses into or out of the province, the New Brunswick permit governs the New Brunswick portion of the trip, and each neighbouring jurisdiction (Quebec, Nova Scotia, or the state of Maine for cross-border moves) issues its own.
How the permit process generally works
In practice, the carrier or a permit service submits the load's overall width, height, length, axle weights, and gross weight, along with the proposed origin, destination, and route. DTI reviews clearances and structures, then returns permit conditions that may specify travel days and hours, speed, lighting and flag/sign requirements, banned travel windows, and the escort configuration. Wider, longer, taller, or heavier loads attract more conditions. The very largest moves — sometimes called superloads — can require a route survey, structural review, and a tightly scheduled travel plan before anything moves.
New Brunswick route and geography realities
New Brunswick's main corridors — the Trans-Canada (Route 2), Route 1 along the southern coast through Saint John, and the connectors into Moncton, Fredericton, and up toward Edmundston and the Quebec line — carry most heavy-haul traffic. The province has a lot of bridges, river crossings, and rolling, forested two-lane secondary routes where a wide or long load leaves little room for oncoming traffic. Height clearances at overpasses and the approaches to border crossings (Maine to the west, Nova Scotia to the southeast) frequently drive the need for a high-pole car to verify overhead clearance ahead of a tall load. Winter weather and seasonal load restrictions on certain roads can also shape when and how a move is permitted.
The escort framework: front, rear, high-pole, steer
New Brunswick uses the same escort positions you'll see across Canada and the US, and the permit tells you which ones apply to your specific load:
- Front / lead pilot: runs ahead of the load to warn oncoming traffic, spot narrow spots, and guide the truck through tight passages — most important on two-lane highways and through towns.
- Rear / chase pilot: follows the load to protect its tail, manage faster traffic coming up from behind, and assist with lane changes and merges, typically required on longer loads or busier divided highways.
- High-pole car: a lead vehicle fitted with an adjustable pole set to the load height, used to physically confirm overhead clearance at bridges, wires, and signs before the load reaches them.
- Steer / steerman: a qualified operator who steers the rear axles of a multi-axle trailer on the largest loads, allowing the combination to track through curves and intersections it otherwise couldn't.
On the biggest or most disruptive moves, the permit may also call for police escort or active traffic control — for example, to hold traffic at an intersection, cross a major bridge, or pass through a congested area. As with everything else, that requirement is set by the New Brunswick permit, not assumed.
General escort reference (always confirm against your permit)
| Escort position | What it does | Typical trigger (general guidance) |
|---|---|---|
| Front / lead pilot | Warns oncoming traffic, scouts narrow points, guides the load | Commonly triggered as width increases, especially on two-lane routes |
| Rear / chase pilot | Protects the back of the load, manages following traffic | Typically with longer loads or on divided highways |
| High-pole car | Verifies overhead clearance ahead of the load | Generally when height approaches overpass/wire clearances |
| Steer car / steerman | Steers rear trailer axles through curves and turns | Usually on very long, multi-axle or superload configurations |
| Police / traffic control | Holds or directs traffic at key points | Varies — reserved for the largest or most disruptive moves |
Confirm before you move
Treat any threshold you read online as a starting point, not a guarantee. The numbers vary by load and by route, and the permit office can add conditions specific to your trip. Confirm the current width, height, length, and weight triggers — and the exact escort configuration — with the New Brunswick Department of Transportation and Infrastructure before the move.

Frequently Asked Questions
When does an oversize load need a pilot car in New Brunswick?
Generally, once a load's width, length, height, or weight exceeds what the province treats as normal traffic, the permit will require one or more pilot vehicles. The exact triggers and the number of escorts are set on your New Brunswick oversize/overweight permit, so confirm them with the Department of Transportation and Infrastructure before the move.
Who issues oversize permits in New Brunswick?
Oversize and overweight permits are issued by the New Brunswick Department of Transportation and Infrastructure (DTI). DTI reviews your dimensions, weight, and route, then sets the permit conditions, including escort and high-pole requirements.
What is a high-pole car and when do I need one?
A high-pole car is a lead pilot vehicle fitted with an adjustable pole set to your load's height. It confirms overhead clearance at bridges, wires, and signs before the load reaches them. It is commonly required when a load's height approaches typical overpass or utility clearances, but the permit makes the final call.
Do New Brunswick rules apply to cross-border US-Canada moves?
The New Brunswick permit governs the New Brunswick portion of any trip. For a cross-border move through Maine, or a move continuing into Quebec or Nova Scotia, each jurisdiction issues its own permit and escort conditions. Heavy Haul Support coordinates escorts across these jurisdictions so the move stays compliant end to end.
