BC Ferries Oversized Vehicle Guide

Taking an RV, truck with trailer, or motorhome on BC Ferries? Here's everything you need to know about vehicle classifications, how oversized availability works, and what to do when oversized spots sell out.

What counts as "oversized" on BC Ferries?

BC Ferries classifies your vehicle on two measurements: height and overall length, including anything you are towing. Go over either one and you are oversized. Their wording is exact, and so is the boundary: "Vehicles under 7 ft. (2.13 m) high and less than 20 ft. (6.10 m) long are considered standard vehicles."

Note where the line falls. Exactly 7 feet is standard, not oversized — BC Ferries writes it as "7 ft. (2.13 m) high or under". Plenty of pages round that to "7 feet or more is oversized", which puts a van measuring exactly 7 ft in the wrong category. And the rounding matters too: the thresholds are 2.13 m and 6.10 m, not 2.1 and 6.1.

Under height, over height, extra length: BC Ferries' own words

Searching for this gets confusing fast, because BC Ferries uses two different vocabularies and neither page tells you the other exists. The booking flow asks you to pick standard or oversized. The fare tariff never says "oversized" at all. It lists three bands, and all three sit inside the category it calls Standard Vehicle:

• Standard Vehicles — Under 7 Ft (2.13m) High. The ordinary car rate. This is what people mean by "under height".
• Standard Vehicles — Over 7 Ft (2.13m) High. The over-height rate. This is "overheight" or "over-height" — a taller vehicle, priced differently.
• Standard Vehicles — Over 20 Ft (6.1m) Long. Length past the first 20 feet is billed as extra length, per foot, on top of the base fare.

So there is no separate "over length" category to be put in, which is the thing most people are actually asking when they search the phrase. Length past 20 feet is a per-foot charge, not a class of vehicle. What "Standard Vehicle" excludes is a bus, or a commercial vehicle, meaning one with a registered gross vehicle weight over 5,500 kg (12,100 lb). A 40-foot motorhome is still a Standard Vehicle on the tariff. A truck over that weight is not, and if either your trailer or the vehicle towing it is over it, BC Ferries charges the whole unit at the commercial rate.

Is my vehicle oversized? Some worked examples

Every row below is just the two thresholds applied. Height is measured to the highest point, and length is the whole unit including a trailer.

Roof racks, roof boxes, bikes and kayaks

This is the single most common way an ordinary car ends up in the oversized pool, and BC Ferries states the rule plainly: "If your vehicle is 7 ft. (2.13 m) high or under, and items on top of your vehicle cause your vehicle height to go over 7 ft. (2.13 m), your vehicle may be considered oversized." A 6 ft 2 in SUV with a cargo box on the roof can clear 7 feet.

There is a second half to that rule which is worth knowing before you arrive, because it can go the other way: "Unreasonably placed items sticking out of the top of your vehicle or items not safely secured on the roof of your vehicle will not be counted towards the overall height measurement and must be removed prior to check-in." Badly secured load, and it does not buy you a taller measurement — it has to come off at the booth.

Why oversized availability is different from standard

This is the part most people don't realize: BC Ferries maintains completely separate reservation pools for standard and oversized vehicles. When you check availability on the BC Ferries website, the results change depending on which vehicle type you select.

This means a sailing can be:

• Available for cars but sold out for oversized — the most common frustrating scenario for RV travelers
• Sold out for cars but available for oversized — less common but it happens, especially midweek
• Sold out for both — peak weekends and long weekends

Why oversized spots are more limited

Ferries have physical constraints that limit how many oversized vehicles they can carry:

• Deck height clearance — only certain vehicle decks have enough vertical clearance for tall vehicles. A standard car deck might be 6.5 feet; oversized vehicles need the main vehicle deck or lower decks with full clearance.
• Deck length — a 40-foot RV takes the space of roughly two cars. Fewer vehicles fit per lane when they're longer.
• Loading logistics — oversized vehicles are harder to maneuver and park, requiring more space between vehicles and careful deck planning by the loading crew.
• Weight distribution — heavy vehicles affect the ferry's balance and trim, limiting how many can be placed on any given deck.

The result: on a sailing that might accommodate 300+ standard cars, there may be space for only 20-40 oversized vehicles. That's why oversized spots sell out faster and reopen less frequently.

Exact dimensions don't affect availability

Here's something that simplifies things: once you're in the "oversized" category, your exact height and length don't change which sailings are available to you. A 22-foot truck sees the same availability as a 45-foot motorhome. BC Ferries uses a single oversized reservation pool, not separate tiers based on dimensions.

Your exact measurements do affect pricing — longer vehicles pay more — but availability is binary: you're either standard or oversized.

Can oversized vehicles drive up without a reservation?

On one direction, no. Sailing from Horseshoe Bay to Departure Bay, every vehicle has needed an advance booking since 15 October 2025, and over-height vehicles get no exemption — there is no oversized drive-up queue there to join. The drive-up and standby rules by route cover which crossings are affected and what to do instead.

Everywhere else: technically yes, but practically, don't count on it.

On Tsawwassen–Swartz Bay, Tsawwassen–Duke Point, Horseshoe Bay–Langdale and the return leg from Departure Bay, drive-up space for oversized vehicles is extremely limited. Standard cars have a decent drive-up allocation, but oversized drive-up spots can be as few as a handful per sailing.

If you show up without a reservation in a motorhome on a summer weekend, you could be waiting multiple sailings — potentially 6-10 hours. For oversized vehicles, a reservation is not optional; it's essential.

What to do when oversized spots sell out

The same cancellation dynamics that apply to standard vehicles apply to oversized — people change plans, cancel trips, and rebook. The difference is that with a smaller pool, each individual cancellation is a bigger deal. One person cancelling their RV reservation might be the only opening that day.

The problem with manually checking

To check oversized availability on the BC Ferries website, you have to:

1. Start the booking flow
2. Select your route and date
3. Enter passenger info
4. Select your vehicle type and enter dimensions
5. View results

That's a 4-step, 30-second process — and you have to do it separately from checking standard availability. Most availability monitoring tools only check standard vehicle availability, so even if they tell you a spot opened up, it might only be for cars, not for your RV.

How FerryHawk solves this

FerryHawk is the only availability monitoring tool that tracks oversized vehicle reservations separately from standard vehicles. When you set up an alert:

1. Select your route and date
2. Switch the vehicle type to Oversized
3. See which sailings are available and which are sold out — for oversized vehicles specifically
4. Tap Notify me on any sold-out sailing
5. Get a text message when an oversized spot opens up

The alert checks oversized availability, not standard. So when you get a notification, you know an oversized spot is actually available — not just a car-sized spot that doesn't help you.

Tips for traveling with an oversized vehicle on BC Ferries

• Book as early as possible — oversized spots are more limited and sell out before standard spots on popular sailings
• Be flexible on timing — early morning and midweek sailings are far more likely to have oversized space
• Set up alerts early — if your preferred sailing is sold out, set a FerryHawk alert immediately. The sooner you're watching, the more cancellation windows you catch.
• Check both directions — if your outbound is sold out, don't forget to also secure your return sailing. Getting stranded on the Island with an RV is worse than not going.
• Measure your vehicle accurately — if you're actually under 7 ft and 20 ft, you can book as standard and have access to the larger reservation pool
• Consider alternate routes — Tsawwassen to Duke Point is less popular than Tsawwassen to Swartz Bay, and both get you to Vancouver Island
• Arrive early even with a reservation — BC Ferries recommends arriving at least 30-60 minutes before departure for oversized vehicles to allow time for loading

Summary

Oversized vehicle travel on BC Ferries comes down to three realities: fewer spots per sailing, a separate reservation pool from standard cars, and very limited drive-up options. The combination makes reservations critical and cancellation openings rare but valuable.

The best strategy: book early, set up a FerryHawk alert on any sold-out sailing, and be ready to book the moment you get the text.

Frequently asked questions

Oversized availability by route

Mainland to Vancouver Island and the Sunshine Coast

• Tsawwassen–Duke Point oversized availability — the most tow-friendly route to the Island
• Tsawwassen–Swartz Bay oversized availability — largest ships, but oversized space still sells out first
• Horseshoe Bay–Departure Bay oversized availability — peak RV and camping route in summer
• Horseshoe Bay–Langdale oversized availability — smallest vessel, scarcest over-height space
• Comox–Powell River oversized availability — boat trailers bound for Desolation Sound

Tsawwassen to the Southern Gulf Islands

Small vessels on multi-stop runs, so the over-height allocation on a sailing is a handful of spots shared across every island it calls at.

• Galiano Island oversized availability — often the first call out of Tsawwassen, which helps
• Mayne Island oversized availability — central, so the deck is rarely empty on arrival
• Pender Island oversized availability — boat trailers are the normal case here
• Salt Spring Island oversized availability — the busiest island, and the fast sailings go first
• Saturna Island oversized availability — no direct sailing, so space is needed on two legs
