Taking your car across the Channel to France is one of the most rewarding ways to explore Europe. You get total freedom to stop at sleepy villages, load up on wine, and discover corners of France that most tourists never see. But before you hit the road, there are rules, requirements, and practicalities you need to know. Get any of them wrong and you could face on-the-spot fines, impounded vehicles, or worse.
This guide covers everything: crossing the Channel, mandatory equipment, French driving laws, tolls, fuel, and the little things that catch British drivers out every single year.
Getting to France: Channel Crossing Options
You have two main options for getting your car from the UK to France, and the right choice depends on your budget, schedule, and where you're headed.
Eurotunnel Le Shuttle
The Eurotunnel runs from Folkestone to Calais in approximately 35 minutes. You drive your car onto the train, stay with your vehicle, and drive off the other side. Departures run up to four times per hour during peak periods. Prices vary wildly depending on when you book and travel dates, but expect to pay between £80 and £300 for a return crossing. Booking well in advance—especially for summer and school holidays—saves significant money.
Ferry Crossings
Several ferry routes connect England to northern France:
- Dover to Calais – 90 minutes, the most frequent and usually cheapest option
- Dover to Dunkirk – around 2 hours, often slightly cheaper than Calais
- Newhaven to Dieppe – 4 hours, useful if you're heading to Normandy or western France
- Portsmouth to Caen – 5.5–7 hours, ideal for Brittany and the Loire Valley
- Portsmouth to Le Havre – 5–8 hours depending on the service
- Portsmouth to St Malo – around 11 hours overnight, perfect for Brittany
- Plymouth to Roscoff – 5–8 hours, great for western Brittany
Pro tip: If you're heading south of Paris, don't automatically choose the shortest crossing. A longer ferry from Portsmouth to Caen can save you hundreds of kilometres of driving and expensive autoroute tolls on the other side.
Mandatory Equipment for Driving in France
France requires you to carry specific items in your car at all times. Police do check, and fines for non-compliance start at €11 but can reach €135.
What You Must Carry
- Warning triangle – must be placed 30 metres behind your vehicle in case of breakdown
- High-visibility vest (gilet jaune) – one per passenger, stored inside the car (not the boot), so you can put it on before exiting the vehicle
- Headlight beam deflectors – UK headlights dip to the left, which dazzles oncoming traffic when you drive on the right. You need stickers or adjustable settings to correct this. Many modern cars have a setting in the headlight menu; check your handbook
- Full driving licence – both parts if you still have the old-style paper licence alongside a photocard
- V5C vehicle registration document – the original, not a photocopy
- Valid motor insurance certificate – a Green Card is no longer mandatory post-Brexit for most insurers, but check with yours
- UK sticker or number plates with UK identifier – since Brexit, the GB sticker is no longer valid; you need a UK sticker or plates that display "UK"
- Passport – must have at least 3 months validity beyond your planned return date
The Breathalyser Situation
French law technically requires you to carry a certified NF-standard breathalyser kit. However, the fine for not carrying one has never been enforced and remains at €0. Most seasoned travellers skip it, but they cost under £5, so it's up to you whether to play it safe.
Pro tip: Buy a "France driving kit" from Halfords or Amazon before you travel. For around £15–25, you get the triangle, vests, headlight stickers, and a breathalyser all in one pack. Much cheaper than buying them at the port.
French Driving Laws and Speed Limits
France drives on the right. This sounds obvious, but it catches people out most often at roundabouts, quiet rural junctions, and when pulling out of car parks or petrol stations. The instinct to drift left is strong—stay alert, especially in the first hour.
Speed Limits
French speed limits are strictly enforced by fixed and mobile radar cameras. The limits are:
- Built-up areas: 50 km/h (about 31 mph)
- Outside built-up areas: 80 km/h (about 50 mph) on single carriageways
- Dual carriageways: 110 km/h (about 68 mph)
- Autoroutes (motorways): 130 km/h (about 81 mph)
In wet conditions, all limits drop: 110 km/h on autoroutes, 100 km/h on dual carriageways, and 80 km/h on open roads. New drivers (less than 3 years' experience) face lower limits too: 110 km/h maximum on autoroutes.
Other Key Rules
- Priorité à droite: In towns, vehicles coming from your right have priority at unmarked junctions. This catches out UK drivers constantly. Watch for diamond-shaped yellow priority road signs—when you see a crossed-out one, you've lost priority
- Drink-driving limit: 0.05% BAC (lower than the UK's 0.08%). In practice, even one glass of wine could put you over
- Mobile phones: Completely banned while driving, including hands-free earpieces. Using a phone carries a €135 fine and 3 points. Bluetooth built into the car stereo is permitted
- Radar detector apps: Illegal. Waze and Google Maps are fine as they show "danger zones" rather than camera locations, but dedicated detector devices can result in a €1,500 fine
- Overtaking: Never overtake on the right on single carriageway roads. On autoroutes, stay in the right lane except when overtaking
Autoroute Tolls: How the System Works
French autoroutes (motorways beginning with "A") are mostly toll roads operated by private companies. They're well-maintained, fast, and expensive. A drive from Calais to the Côte d'Azur can easily cost €80–100 in tolls one way.
How Tolls Work
Most toll sections use a ticket system:
- Take a ticket from the machine when you enter the autoroute (press the button if one doesn't appear automatically)
- When you exit, feed the ticket into the machine at the toll booth (péage)
- Pay the amount shown. Cards are accepted at most booths—look for lanes marked "CB" (carte bancaire). Avoid lanes marked with a "t" unless you have a Télépéage tag
Saving Money on Tolls
- Use the route nationale (N-roads) instead—free but slower, and often far more scenic
- Consider a Télépéage tag if you drive in France regularly—it gives small discounts and lets you breeze through barriers
- Plan your route on ViaMichelin to compare toll costs for different routes
Pro tip: The free N7 from Paris to the Riviera (the historic "Route Nationale 7") is one of Europe's great road trips. It takes longer, but you pass through stunning towns like Valence, Montelimar, and Aix-en-Provence. Plan this trip using our route planner.
Fuel, Parking, and Practical Tips
Fuel
Fuel in France is sold in litres. You'll see:
- Gazole / Diesel – diesel (usually the black pump)
- Sans Plomb 95 (SP95) – unleaded petrol (green pump)
- Sans Plomb 98 (SP98) – premium unleaded
- SP95-E10 – unleaded with 10% ethanol (cheaper, check your car is compatible)
Supermarket fuel stations (Carrefour, Leclerc, Intermarché) are significantly cheaper than autoroute stations—often 15–20 cents per litre less. Plan to fill up before hitting the motorway and at supermarkets along the way.
Parking
In French towns, parking works on a colour-coded system:
- Blue zones – free but time-limited; you must display a blue parking disc (disque de stationnement)
- Pay and display – feed the meter, display the ticket on your dashboard
- Underground car parks – common in cities, take a ticket on entry and pay at the machine before returning to your car
Crit'Air Vignette
Several French cities, including Paris, Lyon, Strasbourg, and Grenoble, operate low emission zones (ZCR/ZFE). You need a Crit'Air sticker displayed on your windscreen. Order it online from the official French government website (certificat-air.gouv.fr) at least 3–4 weeks before travel. It costs €3.72 plus postage. Driving without one in a restricted zone risks a €68 fine.
Planning Your French Road Trip
France is enormous—the largest country in Western Europe—and its regions are strikingly different. Don't try to cram too much in. Here are some of the best road trip routes:
- Normandy and Brittany: Cross from Portsmouth to Caen and explore D-Day beaches, Mont Saint-Michel, and the wild Breton coast. 5–7 days ideal.
- Loire Valley Chateaux: Castle-hop from Chambord to Chenonceau to Amboise. Flat, easy driving through beautiful countryside. 3–5 days.
- Provence and the Riviera: Lavender fields, Roman ruins, hilltop villages, and the glamorous coast from Marseille to Nice. 7–10 days. Plan this trip
- Alsace Wine Route: Half-timbered villages, vineyard-draped hills, and exceptional food. 3–4 days. Perfect in autumn.
- The Pyrenees: Mountain passes, dramatic gorges, and virtually no crowds. 5–7 days for a proper exploration.

Frequently Asked Questions
Do I need an International Driving Permit (IDP) to drive in France?
No. A full UK driving licence is accepted in France for visits of up to 185 days. An IDP is not required. However, if you hold an older paper-only licence without a photo, it's worth carrying your passport alongside it for identification purposes.
What happens if I get a speeding fine in France?
Since 2017, the UK and France share driver data. If you're caught by a speed camera, expect a fine to arrive at your UK address within a few weeks to several months. Fines start at €45 for minor speeding (paid within 15 days) and increase for higher speeds. On-the-spot fines from police must be paid immediately or your vehicle can be impounded. Ignoring a French fine can cause problems on future visits.
Can I use my UK breakdown cover in France?
Most UK breakdown providers (AA, RAC, Green Flag) offer European cover as an add-on. Check your policy before you travel and buy European cover if it's not included. On autoroutes, you must use the orange emergency phones to call for assistance—you cannot call your own breakdown provider. The autoroute operator will send a tow truck (at a regulated price), and your breakdown cover can reimburse you afterwards.
