No speed allowance for overtaking
Since 2022 you may not exceed the 90 km/h limit on conventional roads to overtake.
Low emission zones in cities
Many cities restrict access by the car's DGT environmental label, and cameras read number plates. In central Madrid, a car with a C label, which recent petrol and diesel cars have unless they are hybrids, may enter only to park in a public car park. Each improper trip costs €200. Check each city's rules before you drive in.
Radar detectors are illegal, apps are not
Carrying a radar detector is an offence, and a jammer is a very serious one. Apps and sat navs that warn of camera locations are legal.
Make an emergency corridor in jams
Since 1 October 2026, when traffic on an autopista or autovía slows to walking pace or stops, you must pull over to open a lane for emergency vehicles. With two lanes, the gap goes between them. With three or more, the left lane moves left and the others move right.
Slow down past stopped vehicles
When passing a vehicle stopped on the road after a breakdown or crash, or a road crew, leave at least 1.5 metres and slow to at least 20 km/h below the limit.
Leave roundabouts from the outer lane
Traffic on the roundabout has priority. The inner lanes are for going round. Move to the outer lane before your exit and signal, rather than cutting across from an inner lane.
Speed limits
The sign with the town's name on it sets the town limit by itself, usually with no speed sign.
No passing on the right
On motorways, overtaking on the right is banned. Keep to the right-hand lane unless you're overtaking. Outside towns, on roads with more than one lane in your direction, keep to the right-hand lane. Use the others only when traffic makes it sensible, such as to overtake, and never hold up faster vehicles behind you.
Zonas de Bajas Emisiones (ZBE)
Most zones decide access by the car's DGT environmental label: 0 (blue), ECO, C (green) or B (yellow). Cars with no label are the most restricted. Each city sets its own rules, and some let restricted cars in only to park in a public or private car park. Where: Every town of more than 50,000 people must set one up. The DGT lists Madrid, Barcelona, San Sebastián, Valencia, Seville, Zaragoza, Bilbao and Málaga among the main ones. A Spanish hire car is already classed by its DGT label, shown on the sticker in the bottom right corner of the windscreen. Foreign-registered cars cannot get a Spanish label but can use the equivalent label from their home country, and some cities such as Barcelona ask them to register in advance.
Madrid ZBE (whole city)
Cars with a 0, ECO, C or B label can drive in freely. Cars with no label are banned unless registered in Madrid and paying the city's vehicle tax, or exempt. Where: The whole municipality of Madrid, 24 hours a day. The M-40, M-45 and M-50 ring roads are outside the zone. Fine: €200. Petrol cars registered since 2001 and diesel cars since 2006 have at least a B label, so only older cars are affected.
Madrid Distrito Centro (ZBEDEP)
Only cars with a 0 or ECO label may drive in freely. Cars with a C or B label may enter only to park in a public car park or under another exception, and cars with no label are banned. Where: Central Madrid, the former Madrid Central area. Fine: €200 for each improper trip. A petrol car registered since 2006, or a diesel since September 2015, has a C label unless it is a hybrid, which gets ECO. With a C label, drive in only to a public car park, or leave the car outside the centre. Cameras read number plates and the fine arrives by post.
Toll roads
The vast majority of Spain's roads are free to use. The toll motorways (autopistas de peaje) that remain charge at booths, which take cash or bank cards. On most toll motorways you take a ticket when you join and pay when you leave. Some sections charge one fixed toll. State toll motorways still charging in 2026 include the AP-6, AP-9, AP-46, AP-51, AP-53, AP-61, AP-66, AP-68 and AP-71, the AP-7 between Málaga and Guadiaro, between Alicante and Cartagena and between Cartagena and Vera, the AP-36 (Ocaña to La Roda), the AP-41 (Madrid to Toledo), the M-12 and the R-2, R-3, R-4 and R-5.
Park on the right on two-way streets
On a two-way street you may park only on the right-hand side in your direction of travel, so never facing oncoming traffic. Only on one-way streets may you also park on the left.
Drink driving
The blood alcohol limit is 0.05, and 0.03 for licence held for less than 2 years. The breath limits are 0.25 mg/l, or 0.15 mg/l for novice and professional drivers.
