When the wheelchair bay is free, it can be possible to put large bags there. Buses are not designed to accommodate large items of luggage as there main purpose is to enable passengers to hop on and off over short distances and as coaches and shuttle services provide more customised options.

In 2026, the rules for taking large items on a bus depend heavily on the type of service and the specific transit agency. For local city buses, the general rule is that an item must be small enough to fit in your lap or under your seat without blocking the aisle or taking up an extra seat during peak hours. Items like foldable bikes or strollers are usually allowed, provided they are collapsed before boarding. For long-distance coaches like Greyhound or FlixBus, you are typically allowed one large item (like a suitcase or a musical instrument) to be stored in the under-carriage luggage compartment for free or a small fee, as long as it meets weight limits (usually around 50 lbs). Oversized items like surfboards, non-folding bicycles, or large skis often require a specialized "oversized" ticket and must be pre-booked. Always check the specific "Conditions of Carriage" for your bus line, as drivers have the final discretion to refuse any item that poses a safety hazard or significantly inconveniences other passengers.
