Driving your own car to Europe remains one of the most flexible ways to travel, especially in early autumn when school-holiday traffic has gone and ferry and Eurotunnel prices tend to ease off. But the rules of the road change the moment you leave the ferry or tunnel, and unfamiliar laws or worn tyres can quickly turn a holiday into a costly problem.
Before crossing the Channel, a full vehicle check is essential. Tyres deserve particular attention: a car loaded with luggage, a roof box and passengers, driven for hours at motorway speeds and then over rough tracks, puts significant strain on the rubber. The legal minimum tread depth in the UK and most of Europe is 1.6mm across the central three-quarters of the tyre, but tyre specialists recommend replacement at 3mm because stopping distances lengthen noticeably below that. The 20p test is a simple DIY check: insert a coin into the main grooves and if the outer band is visible, new tyres are needed. Tyre pressures also need adjusting for extra load, with the correct figures usually found on a sticker inside the driver's door, on the fuel filler cap or in the handbook.
Paperwork has become simpler since the early post-Brexit years. A green card is no longer required to prove insurance cover in the EU, and an International Driving Permit is only needed for old-style paper licences or ones issued in Gibraltar, Guernsey, Jersey or the Isle of Man. Drivers should still carry a passport valid for at least three months beyond the return date, a full driving licence and proof of insurance. If the car is not registered in the driver's name, the V5C logbook or a VE103 permission-to-drive form is required. A free Global Health Insurance Card (GHIC) is also worth packing alongside travel insurance.
Number plates and headlights are common stumbling blocks. A UK sticker is required on the rear of cars with an older GB flag or no flag at all, and Spain, Cyprus and Malta demand the sticker regardless of the plate. Reusable magnetic versions are available, but not all tailgates are made of steel, so testing with a small magnet first is wise. Headlight beam deflector stickers, costing only a few pounds, prevent dazzling oncoming traffic when driving on the right; some cars with adaptive headlights can be switched to right-hand traffic in their settings.
Safety kit requirements vary by country, but most of Western Europe mandates a warning triangle and a hi-vis vest for every seat, kept accessible in the cabin rather than the boot. A first aid kit is compulsory in several countries, and spare bulbs are worth carrying because a blown headlight can mean an on-the-spot fine abroad. Although breathalysers stopped being a legal requirement in France in 2020, they remain sensible given strict French drink-drive limits.
Speed limits and drink-drive rules differ from country to country and rarely match what drivers are used to at home. In France, for example, the limit is 50km/h in towns, 80km/h on most trunk roads and 130km/h on dry motorways, dropping to 110km/h in wet conditions. Checking each country's rules before crossing a border avoids unpleasant surprises.
