There is no common European rule
The most common mistake with this question is assuming that what one operator told you carries over to the next. It does not. Two of the largest operators on the same sea use tests that are the opposite of each other, and a driver who has crossed the Baltic without trouble for years can be turned back at an Irish Sea check-in for exactly the same vehicle.
Scandlines works with a number. Vans and minibuses with a permitted gross weight above 3,500 kilograms have to be booked through the freight department; below that the booking runs through the ordinary passenger side. The car tariff itself applies to vehicles up to six metres in length that are registered for no more than nine people and up to 3,500 kilograms. What you have loaded and why you are travelling makes no difference.
Stena Line works the other way round. Vans carrying goods or equipment for commercial purposes have to go through freight regardless of the size of the vehicle. A small van that fits comfortably inside every car dimension is still freight the moment it carries tools for a paid job. On top of that, private vans over six metres in length also count as freight, even with nothing commercial on board at all.
The same pattern, with local numbers
| Operator | What decides the category |
|---|---|
| Scandlines | Permitted gross weight: above 3,500 kg through the freight department |
| Stena Line | Purpose first, then length: commercial goods always freight, private vans from 6 m freight |
| Baleària | Private vans over 6 m as cargo; a commercial purpose means cargo at any length |
| Polferries, Unity Line | Private vans above 3.5 t as cargo; a commercial load means cargo at any weight |
Read the table as a warning rather than a shortcut. It shows how far apart the criteria sit, not what your particular crossing will cost. Operators outside this list have their own rules again, and the conditions change with the seasonal fare sheets. Check the current terms of the operator you are actually sailing with before you book.
Crossing to or from the UK and Ireland adds a customs layer
On the routes between Great Britain, Northern Ireland and the Republic of Ireland the tariff question and the customs question are tangled together. Stena Line requires vans of any size that carry goods or equipment for commercial purposes to be booked through freight reservations on the Cairnryan to Belfast and Liverpool to Belfast routes wherever a Goods Movement Reference is needed. Low-value goods are carved out: the published thresholds are 873 pounds into Northern Ireland, 1,500 pounds into Great Britain and 260 euros into Ireland.
On routes to the Republic of Ireland, vans up to and including twelve metres have to be declared when booking, and anything longer has to be booked as freight. Vehicles registered in Ireland and taxed there as commercial goods vehicles attract VAT from seven metres upwards, and express boarding is not offered for vans over seven metres either. None of this depends on what the vehicle looks like; it depends on how it is registered and what it carries.
Length is measured at the terminal, not in the paperwork
What counts is what actually takes up space on the deck. Stena Line states that it is always the total height and length of the vehicle that matters, including every conceivable accessory such as roof boxes and bicycles. Scandlines measures overall length including towbar, attached trailer and fitted bike rack. A vehicle listed at 5.90 metres can cross the six-metre mark with a rear carrier and drop into the next price band.
Booking the wrong vehicle type is not a formality either. Operators reserve the right to charge a supplement, and in the worst case the vehicle is not accepted at check-in at all. On Scandlines the length bands are published: no surcharge up to six metres, then 20 euros between six and eight metres, 40 euros between eight and ten, 60 euros between ten and twelve, and 80 euros above twelve metres, where booking is often no longer possible at all. Those figures are the state of this research and move with the seasonal price lists.
What you have loaded can trigger its own rules
Separately from the tariff category, certain cargo carries its own conditions. Gas bottles have to be closed before you drive on board, and Color Line additionally asks that access to the containers stays unlocked where possible so they can be removed in case of fire. Stena Line points out that batteries from electric bicycles should not be taken into passenger areas or cabins for safety reasons; the battery stays with the bike on the car deck for the crossing.
How to book it right
Settle three things before you book: the permitted gross weight from the registration document, the real total length with everything attached, and whether the trip is commercially motivated. With those three figures you can place yourself in the right category with any operator. When in doubt the freight booking is the safe route - it is more cumbersome, but it does not get turned away at the terminal.
Frequently asked questions
My van has a gross weight of exactly 3.5 tonnes. Car or freight?
At Scandlines the threshold is above 3,500 kilograms, so a vehicle with exactly 3,500 kilograms permitted gross weight still falls inside the passenger booking. What counts is the permitted gross weight on the registration document, not the actual laden weight.
I am driving my own tools to a job abroad. Is that commercial?
At Stena Line, yes: goods or equipment carried for commercial purposes mean a freight booking whatever the size of the van. At Scandlines the same trip stays an ordinary passenger booking as long as the vehicle is under the weight limit. This is the clearest example of why one operator's answer does not transfer to another.
Does a bike rack really count towards vehicle length?
Yes. Operators measure the vehicle as it presents itself at the ramp, including towbar, trailer and rear carrier. If you are just under a length threshold, a fitted rack can push you into the next price band. Taking it off and stowing it inside is often cheaper than the surcharge.
What happens if I turn up with the wrong ticket?
The operator can refuse carriage on the booked tariff and insist on rebooking. In practice that means paying the difference and waiting for the next departure with space. How individual operators handle it in detail is not uniformly published, which is exactly why it is worth avoiding.
Is freight cheaper than the passenger tariff?
Not as a rule. Freight tariffs follow a different logic, often billed by lane metres rather than vehicle length, and they include different services. A blanket comparison is not possible; price both options for your specific route and date.
Can I sleep in the van on board, like in a motorhome?
No. Camping on board, where it is offered at all, is limited to vehicles registered as motorhomes or caravans. On overnight crossings you book a cabin or a reclining seat.
