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 based on two measurements: height and total length (including any trailer). If your vehicle exceeds either threshold, it's considered oversized.

If your vehicle is over either limit, it's oversized. A sedan towing a 16-foot trailer totaling 30 feet? Oversized. A tall camper van at 7.5 feet? Oversized. A compact SUV under both limits? Standard.

Common oversized vehicles

• Motorhomes and Class A/B/C RVs — almost always oversized on both height and length
• Trucks with trailers — total length (truck + trailer + hitch gap) usually exceeds 20 ft
• 5th wheels and travel trailers — the towing vehicle + trailer combined length is what matters
• Tall camper vans — stock Sprinter vans are right at the limit; aftermarket roof raises push them over
• Commercial vehicles and box trucks — typically oversized on both dimensions
• Vehicles with roof cargo — a roof box or kayak rack can push a borderline vehicle over 7 ft

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?

Technically yes, but practically, don't count on it.

On major routes (Tsawwassen–Swartz Bay, Tsawwassen–Duke Point, Horseshoe Bay–Departure Bay, Horseshoe Bay–Langdale), 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.
