British Columbia Oversize Load Permits, Regulations & Axle Rules

BC sorts permit travel into categories that tighten as a load grows. Category A (up to 3.2 m wide) runs any time, any day. Category B (up to 3.8 m) and Category C (up to 4.4 m) move most days but lose General Holidays and pick up corridor-specific curfews: the South Coast closes weekday peaks of 07:00 to 09:00 and 15:30 to 18:00 to wide loads, and a stretch of Highway 1 between Hope and Cache Creek bars travel during darkness.

Over 4.4 m wide the load enters the Extraordinary Load tier, and most districts push it into a night window: 22:00 to 05:00 weekdays and midnight to 05:00 weekends. Northern districts like Bulkley Stikine and Skeena shift that to 19:00 to 07:00, and the Okanagan runs midnight to 05:00 from May 1 to September 30 for the widest moves. The Peace River Region is more generous, holding extraordinary rules until a load clears 5.33 m high.

No oversize load moves on a Sunday or general holiday without an express permit allowance. The Poor Visibility rule applies across all categories: if persons or vehicles on the highway aren't clearly discernible at 100 m, the move stops.

Logging trucks get the most detailed carve-out. A two-vehicle log combination with a single articulation point runs to 21.5 m overall; more than one articulation point stretches that to 23.0 m, provided the load can't be shortened without cutting the wood. Gross weight caps at 63,500 kg, with seasonal overweight allowances, the December-to-March window being larger than the March-to-November one.

Loose hay, straw, or fodder projecting over the sides is allowed up to 3.1 m wide before counting as oversize (the standard cap is 2.6 m). Implements of husbandry are width-exempt in daylight; at 3.7 m or wider a front sign and flags on all four corners are required. Buses run their own length ladder: 12.5 m for two-axle, 14 m for three-axle, 20 m for articulated.

Mobile homes are the standout on the wide end. A manufactured home over 5.0 m wide in the Okanagan, Thompson-Nicola, and Rocky Mountain districts needs four pilot cars, with the fourth car dedicated to managing traffic entering from side roads.

BC calls its top tier an Extraordinary Load. A move hits that threshold by clearing any one of these: more than 4.4 m wide (unless pre-approved under CVSE1001 up to 5 m, or CVSE1002 up to 6.1 m in the Peace River Region), more than 4.88 m high (5.33 m in the Peace), more than 40 m long (except in the Lower Mainland), more than 85,000 kg gross, or more than 64,000 kg on a route not approved for overload (in which case the load must be stripped or fully reduced before approval). A non-reducible oversize load travelling more than 110 km also qualifies.

This isn't a same-day counter permit. The carrier files a CVSE1049 Extraordinary Load Approval Request with clear, legible diagrams of the load and configuration. Loads over 6 m wide or over 4.88 m high add a CVSE1052 per district crossed, gathering sign-offs from utility companies and district offices. Where Special Bridge Crossing Conditions apply, a CVSE1053 must be on file at the Provincial Permit Centre before any permit issues.

Extraordinary Load approvals are typically valid for about 180 days.

BC folds the route survey into the Extraordinary Load Approval. The carrier starts by reviewing the intended route on the province's Commercial Vehicle Routing Tool to flag known dimensional limits, then documents the route and configuration on the CVSE1049.

The bridge side is a formal review. Every affected crossing gets checked, and a prior Bridge Approval (Overload) number (the OL-series reference) must generally be in place. Those bridge approvals run about five years; the overall extraordinary-load approval runs about 180 days. Loads over 6 m wide or over 4.88 m high trigger the CVSE1052 process, routing sign-off out to districts and utility owners. In the Peace, a load over 6 m high must clear that CVSE1052 sign-off with the regional power utility specifically.

A Transportation Management Plan may also be required for loads over 6 m wide or any move that needs a highway shutdown. When Special Bridge Crossing Conditions apply, the CVSE1053 must be on file at the Provincial Permit Centre before the permit is granted.

BC has no mandatory police-escort tier. Escorting is all civilian pilot cars, scaling with width, length, and road type. On a two-lane highway: over 3.2 m wide needs one pilot car, over 3.8 m needs two. On a multi-lane highway the first pilot car isn't required until the load exceeds 3.8 m. Length and projection add their own, and once a load enters the Extraordinary Load tier over 4.4 m wide, district tables call for three pilot cars, rising to four for manufactured homes over 5.0 m wide.

Law enforcement enters only in two limited roles. For loads over 6 m wide or over 4.88 m high, the CVSE1052 process may require the carrier to notify the RCMP, but that's a notification recipient, not an escort. Where active traffic control is needed, a certified traffic-control person handles it, or optionally a Peace Officer.

Neither amounts to a booked sworn-officer escort. Plan around certified civilian pilot cars and handle any RCMP notification through the extraordinary-load approval process.
