Hiring a car in Spain opens up a world of sun-drenched beaches, historic towns, and stunning countryside beyond the tourist hotspots. But driving on the right-hand side of the road is just the beginning; Spanish roads have their own unique rules and etiquette that can catch out unprepared British drivers.
From understanding motorway speed limits to navigating the infamous 'magic roundabouts', this guide has everything you need to know for a safe and confident driving holiday in Spain in 2026. We'll cover the essential documents, local laws, and practical tips to make your road trip a breeze.
Clever things to do in spain
Essential Documents and Kit
You must carry your valid UK driving licence, passport, and rental documents at all times. By law, your car must also contain two warning triangles, reflective jackets for all occupants, and a spare wheel or tyre repair kit. Your rental car should come with these, but it's wise to check.
Understanding Spanish Speed Limits
Speed limits are strictly enforced. They are typically 120 km/h (75 mph) on motorways (autopistas), 90 km/h (56 mph) on main roads (carreteras nacionales), and 30 km/h (19 mph) in many urban areas. Be aware of variable speed limits indicated on overhead gantries.
Mastering Spanish Roundabouts
This is a big one for Brits. Traffic on the roundabout has priority, and you must give way to traffic already on it, approaching from your left. Crucially, drivers in the outer lane have priority when exiting, so be cautious of cars on your outside cutting across you.
Parking Rules and Zones
Look out for coloured lines. Blue lines ('zona azul') indicate paid parking, where you'll need to use a pay-and-display machine. Yellow lines mean no parking, and green lines are typically for residents only. Fines are issued frequently, so always check local signage.
Low Emission Zones (ZBEs)
Many Spanish cities, including Madrid and Barcelona, operate 'Zonas de Bajas Emisiones' (ZBEs). Your modern hire car should have the required eco-sticker to enter, but it's vital to be aware of these zones to avoid hefty fines. Check your planned route for any restrictions.
Know before you go
While a UK photocard licence is generally accepted, official advice post-Brexit is to carry a 1968 International Driving Permit alongside it. It's a simple and cheap document to obtain from the Post Office and removes any potential ambiguity with local police.
Fuel names can be confusing. 'Gasolina' is petrol, and 'Gasóleo' or 'Diésel' is diesel. Unleaded petrol is 'Sin Plomo 95' or 'Sin Plomo 98'. Double-check the sticker inside the fuel cap of your hire car to avoid costly mistakes.
Spanish drivers can be assertive, often driving very close behind before overtaking. Don't be intimidated; maintain a steady speed in the right-hand lane unless you are overtaking, and always indicate your manoeuvres clearly and early.
The Spanish police (Guardia Civil) can and will issue on-the-spot fines for traffic violations, which you'll be expected to pay immediately. A discount is often applied for prompt payment, so it's wise to have a credit card handy.
