Driving onto a ferry is a different experience from boarding as a foot passenger. You queue in lanes, your car is guided into the vessel's hold by marshals, and you leave it there — often for several hours — while the crossing happens. The process is well-organised on established routes, but a few things catch first-timers out. Here is what to know before you arrive at the port.
Booking a vehicle space
When you book a ferry crossing with a car, you buy a vehicle space in addition to your passenger ticket. The vehicle fare is based primarily on the car's length — standard saloons, estates and hatchbacks typically fall into the same bracket, while longer vehicles such as people-carriers, SUVs with roof boxes, campervans and caravans attract a higher tariff. On some routes you are also asked for the car's height, particularly on overnight services where deck-height restrictions apply.
You will need the vehicle's registration number and usually the make and model when booking. It is important that the details match: port check-in staff may compare what you arrive with against what is on the booking. Taking a hire car across a border on a ferry also requires permission from the rental company — see taking a rental across borders for the specifics.
Check-in: when to arrive and what to expect
Vehicle check-in closes significantly earlier than the sailing time — typically 45 minutes to an hour before departure on most routes, and sometimes longer on busy crossings such as Dover–Calais in peak summer. This is not a suggestion; miss it and you may be turned away even if the ship has not yet sailed.
On arrival at the port, follow signs for the ferry operator and join the vehicle lanes. Staff will check your booking reference (usually a QR code or booking number on your phone or printed confirmation), your passport or identity document, and may weigh or measure taller vehicles. Once processed, you are directed to a holding lane to wait for loading.
Arrival timing matters: on the English Channel crossing from Dover, summer queues at the port can add significant time even before check-in. The DFDS and P&O websites both publish live port status. Arriving 90 minutes before your sailing in peak season is not excessive.
On the vehicle deck
Loading is directed by ship's crew. You drive to your assigned position on the car deck and, once parked, apply the handbrake and follow any instructions — on rough-sea routes you may be asked to leave it in gear as well. The car deck is not a public area once the ship is underway: on most crossings you are required to leave the vehicle deck as soon as you have collected what you need (jackets, bags, children's entertainment) and go up to the passenger decks. You will not be able to return until the vessel is close to docking.
Make sure you take everything you will need for the crossing before leaving the car. On overnight ferries, this means sleepwear, toiletries and any medication — not a quick trip back to the boot.
Campervans, caravans and larger vehicles
Campervans and caravans are booked in their own category, usually as a combined length (vehicle plus tow or interior measurement). The height of your vehicle also matters: some car ferries have lower deck-height limits, particularly on older vessels. Check the operator's vehicle specifications carefully before booking. Operators including Brittany Ferries and Stena Line have detailed tables on their sites.
On some overnight routes, campervan passengers can elect to sleep in their vehicle if it is parked on an open or ventilated deck — but this is not always permitted, and you usually need to confirm this possibility at booking. Do not assume it is allowed.
Motorcycles and bicycles
Motorcycles pay a vehicle tariff that is lower than a car on most routes, and are loaded and secured on the car deck — usually tied down by crew. Bicycles are handled differently: on many routes they are rolled on as hand luggage and secured in a designated bicycle area rather than the main car deck. Fares for bicycles are typically low or sometimes included in the foot-passenger fare. Confirm with the operator at the time of booking.
Electric vehicles and charging
Most car ferries do not offer on-deck charging for electric vehicles during the crossing, though some newer vessels on Scandinavian and Nordic routes are beginning to introduce it. If you are taking an EV, plan your route to charge before port, and check in advance whether shore power is available on your specific vessel. This is an area where the situation is changing quite fast — check with the operator before you travel.
Vehicle security on the car deck
The car deck is locked once everyone has disembarked upstairs, but it is accessible to ship's crew. Leaving valuables in a visible position in the car is not ideal, particularly on longer overnight crossings. Most ferry operators carry a waiver that limits their liability for items left in vehicles, so treat the car as you would any parked vehicle in a public space.
Disembarking with a vehicle
Return to the car deck before docking — a tannoy announcement will tell you when passengers are allowed back down. Do not rush; disembarkation on a large ferry is an orderly process and the crew direct traffic. Follow the lane signs and take your time on the ramps, particularly if the ship is moving in a swell. Ramps can be steep and slippery.
At the destination port, customs and border officials may stop vehicles for checks, particularly on routes that cross from one legal zone to another — the UK–France Channel crossing and Spain–Morocco crossings involve customs checks. Keep your documents accessible, including any vehicle insurance green card if required.
Frequently asked questions
Can I stay in my car during the crossing?
On most car ferries you are required to leave the vehicle deck once you have parked and the ship is underway. You can return shortly before arrival when the announcement is made. A small number of overnight routes permit sleeping in campervans on open decks — always confirm with the operator.
How early do I need to arrive at the port with a car?
Vehicle check-in closes well before sailing — typically 45–60 minutes beforehand, and more on busy crossings. Arrive at the port at least 90 minutes before departure if you are unsure, and earlier still in peak summer.
Do I need extra insurance to take my car on a ferry?
Your standard car insurance usually covers the car deck passage, but always confirm with your insurer. For cross-border crossings, check whether your policy is valid in the destination country and whether you need a green card.
What size vehicle counts as oversized on a ferry?
Definitions vary by operator, but vehicles over about 5 metres in length, or with a roof height above roughly 1.8–2 metres, often attract a higher tariff or require booking in a specific category. Always check the operator's vehicle size chart before booking if your vehicle is larger than a standard car.
