FAQ | Alcohol Limit Spain, BAC & Drink Drive Rules

The legal alcohol limit in Spain for regular drivers is 0.5 g/L of blood (50mg per 100ml), or equivalently 0.25 mg/L of breath. That works out to roughly 0.05% BAC — the same threshold as France, Italy, and most other EU countries, and notably lower than the UK's 0.08%. Novice drivers in their first two years post-licence, and professional drivers (taxi, bus, lorry, transport of dangerous goods), must stay below 0.3 g/L (0.15 mg/L breath).

At 0.60 mg/L of breath (about 1.2 g/L blood) or above, drink driving stops being an administrative offence and becomes a delito contra la seguridad vial under Article 379 of the Penal Code — a criminal offence carrying prison time. There is no safe amount of alcohol to drink before driving in Spain: a single caña and a glass of wine can put many drinkers close to 0.5 g/L. Use the calculator above for an estimate of your blood alcohol content, but treat it as guidance — if there is any doubt, do not drive.

Drink driving penalties in Spain are tiered by your BAC. Between 0.25 and 0.50 mg/L of breath (or 0.15–0.30 for novice and professional drivers), the offence is administrative: a fine of €500, −4 licence points, and possible roadside vehicle immobilisation. Above 0.50 mg/L of breath, or if you are a repeat offender within one year, the fine rises to €1,000 and you lose −6 points.

From 0.60 mg/L of breath upwards, drink driving becomes a criminal offence under Article 379 of the Penal Code: 3 to 6 months in prison, OR a 6–12 month daily-rate fine, OR 31 to 90 days of community service, plus licence withdrawal for 1 to 4 years and a permanent criminal record. Refusing the breath or blood test is itself a criminal offence under Article 383 (desobediencia grave) and carries 6 months to 1 year in prison plus the same 1–4 year licence withdrawal. Causing injury or death while intoxicated triggers significantly longer prison terms under Articles 142 and 152 of the Penal Code.

For novice drivers, the alcohol limit in Spain is 0.3 g/L of blood (0.15 mg/L of breath) — well below the 0.5 g/L threshold for experienced drivers. This applies during the entire probationary period: two years after passing your Spanish driving test (permiso de conducir). The same 0.3 g/L limit applies to professional drivers — taxis, buses, coaches, lorries, and transport of dangerous goods — at all times, regardless of how long they have held a licence.

A novice driver caught above 0.15 mg/L of breath faces a fine of €500 and −4 licence points; above 0.30 mg/L breath (or 0.60 if their reading enters the criminal range), penalties jump to €1,000, −6 points, and possible prosecution under the Penal Code. Because novice licences start with 8 points (rather than the standard 12), a single drink-driving offence can put a new driver close to losing the licence entirely.

No. Under Article 383 of the Spanish Penal Code, refusing to submit to a breath, blood, or urine alcohol test in Spain is itself a criminal offence — classified as desobediencia grave (serious disobedience). The penalty is 6 months to 1 year in prison plus licence withdrawal for 1 to 4 years. Crucially, this is the same severity as the criminal drink-driving offence under Article 379 — refusing does not let you avoid the consequence, it just changes which article you are prosecuted under.

Spanish police (Guardia Civil de Tráfico, Policía Local, Mossos d''Esquadra in Catalonia, Ertzaintza in the Basque Country) can request a breath test with or without cause — at random roadside checkpoints, after a traffic stop, or following an accident. There is no right to refuse and no benefit to choosing the criminal-disobedience sanction. If you believe a device is faulty, you can request a follow-up blood test at a hospital, but you must comply with the initial roadside breath test first.

There is no honest "safe count" because the same drink affects two people very differently depending on weight, sex, food intake, and metabolism. As a rough guide for an average adult man (~75kg) drinking with food, one Spanish UBE (10g of pure alcohol — a 200ml caña of beer at 5%, a 100ml copa of wine at 12%, or a 30ml shot at 40%) typically pushes blood alcohol to around 0.2–0.25 g/L. A second UBE often crosses the 0.5 g/L limit. For an average woman (~60kg), one UBE alone can be enough to reach 0.5 g/L.

For novice and professional drivers (limit 0.3 g/L), even a single drink is likely too much. Food slows absorption and can lower peak BAC by 20–25%, but it does not stop you from going over the limit. The only reliable rule is to not drink at all if you plan to drive — and use the calculator above to estimate your BAC against the appropriate limit for your driver category.

The DGT and Guardia Civil de Tráfico run random alcohol checkpoints year-round, but enforcement is sharply reinforced during officially announced Operaciones Especiales: around Christmas and New Year, Semana Santa, summer driving (July and August, when domestic tourism peaks), and major holiday weekends. The DGT publishes these campaigns in advance on dgt.es and Spanish media. Outside these periods, checkpoints concentrate on Friday and Saturday nights, near nightlife districts, on routes to the coast, and at the entry points to major cities.

Local police forces — Policía Local in each town, Mossos d''Esquadra in Catalonia, Ertzaintza in the Basque Country, Policía Foral in Navarre — also run their own checkpoints, especially near bar and club districts at closing time. Tourists driving on a foreign licence are subject to exactly the same limits and penalties as Spanish residents, and a foreign driver who tests above the criminal threshold (0.60 mg/L breath) can be prosecuted under Article 379 of the Spanish Penal Code just like a local.

In Spain, your blood alcohol level can be measured in three ways and the law sets a threshold for each. The legal limit for regular drivers is 0.5 g/L of blood (also written 0.5‰ or 50mg/100ml), 0.25 mg/L of exhaled breath, or equivalently ~0.05% BAC on international scales. For novice and professional drivers the limits are 0.3 g/L blood and 0.15 mg/L breath. The Penal Code criminal threshold (Article 379) is set in breath units: 0.60 mg/L.

At the roadside, police use a breath test because it's fast and non-invasive; blood samples can be taken later at a hospital for evidential testing if the breath result is contested. The three units each have their own legal threshold and are not freely interchangeable, but the conversions are stable enough that BAC % and g/L are commonly used in parallel — 0.5 g/L equals 0.05% BAC. Our calculator lets you switch units to match whichever figure you have in mind.

Spanish police evidential breathalysers (typically Dräger devices, certified by the Centro Español de Metrología) carry a small margin of error: usually around ±5% on the displayed reading. The handheld screening devices used at the roadside checkpoint are less precise; the evidential machine — used after a positive screen — provides the legally usable reading for prosecution.

This tolerance does not give drivers a buffer. If the evidential reading puts you over the limit, you can be sanctioned — the margin is built into how the devices are certified for court use. Consumer-grade personal breathalysers are noticeably less accurate than police equipment and lose calibration over time, so a borderline reading on a personal device should be treated as "definitely don''t drive". The safest course is never to drink and drive rather than to rely on a reading sitting close to 0.5 g/L.

On average, your body clears roughly one Spanish UBE (10g of pure alcohol) per hour, but this is only a rule of thumb — body weight, sex, metabolism, food, and general health all change the pace. As a guide, it can take around 2–3 hours to eliminate a 330ml tercio of beer, two cañas, two small glasses of wine, or two single measures of spirits, and considerably longer after a heavy evening of tapas and copas.

This is why the morning after catches so many drivers out in Spain: if you drank heavily into the small hours, you can still be over 0.5 g/L the next morning, even after a full night's sleep. Sleep, coffee, water, and a shower may make you feel more awake, but they do not lower your BAC. The safest approach is to wait until you are certain all the alcohol has gone and you feel completely sober — and to use our calculator to estimate when that will be.

For police use, Spanish roadside screening relies primarily on devices from Dräger (e.g. Alcotest 7510, 6820) — the same brand used by police in France, Germany, and most of the EU. Evidential breath analyzers at police stations are typically Dräger Alcotest 9510 units, certified by the Centro Español de Metrología. These deliver the legally usable reading once the roadside screen is positive.

For personal use, the consumer breathalyser market in Spain is dominated by reusable electronic devices from brands such as Dräger, AlcoSense, ACE, and BACtrack — sold through Amazon, El Corte Inglés, and specialised retailers. Personal devices are useful for awareness, especially the morning after, but they lose accuracy over time and cheaper models can be unreliable. A consumer reading close to 0.5 g/L should always be treated as "do not drive".

Your body removes alcohol at a fairly steady rate — roughly 0.15 g/L per hour (about one Spanish UBE per hour), and nothing reliably speeds this up. Starting from a BAC of 1.0 g/L, it would therefore take in the region of 6 to 7 hours for the alcohol to clear completely; from 1.5 g/L, closer to 10 hours.

That figure is an estimate, not a guarantee. The actual time depends on your weight, sex, metabolism, whether you have eaten, and your general health, so two people who reach the same BAC can sober up at different speeds. Note that you would be over the 0.5 g/L Spanish limit long before your BAC reaches zero — if you started at 1.0 g/L, you'll still be over the limit for about three to four hours. Use our calculator for a personalised estimate.

The honest answer is that you cannot sober up faster. Your liver breaks down alcohol at an essentially fixed rate, and only time lowers your blood alcohol content. Popular "remedies" — black coffee, a cold shower, fresh air, exercise, a big meal after drinking, or being sick — do not change how quickly alcohol leaves your system.

What some of these can do is make you feel more alert, and that is precisely the danger: feeling more awake while your BAC is still high can fool you into thinking you are fit to drive when you are not. Coffee, for example, masks tiredness without touching your alcohol level. Drinking water is sensible for rehydration and may ease a hangover, but it does not speed up sobering up. The only safe plan is to wait — use our calculator to estimate when your BAC should be back below the 0.5 g/L limit, and then back to zero.

In Spain, alcohol is measured in UBE — Unidad de Bebida Estándar. One UBE contains 10g of pure alcohol — the amount an average adult's body can process in roughly one hour. To work out the UBE in any drink, multiply its volume in millilitres by its strength (ABV %) and by 0.79 (the density of ethanol), then divide by 10: (volume × ABV × 0.79) ÷ 10.

A 200ml caña of beer at 5% is about 1 UBE, a 100ml copa de vino at 12% is 1 UBE, and a 30ml shot of spirits at 40% is approximately 1 UBE. Wider drinks count more: a 330ml tercio (bottle) of beer is closer to 1.3 UBE, and a generous gin and tonic served Spanish-style (50–60ml of spirit) is around 1.5–2 UBE. Spain's Ministerio de Sanidad considers daily intake above 2 UBE/day for men and 1 UBE/day for women as elevated risk.

How long alcohol stays in your system depends on what is being tested. Alcohol itself can usually be detected in your breath for up to about 24 hours, in blood for up to 24 hours, in urine for up to 48 hours (longer with specialised tests for the EtG metabolite), in saliva for 1–5 days, and as traces in hair for up to 90 days.

These detection windows are much longer than the time it takes to become safe to drive. Your blood alcohol content falls steadily at roughly 0.15 g/L per hour, so the figure that matters for driving is when your BAC drops below 0.5 g/L (or 0.3 g/L if you're a novice or professional driver) and then to zero — typically a matter of hours after a moderate evening, not days. Detection times also vary with the amount you drank, your metabolism, and your overall health. Use our calculator for a personalised estimate.

Spain has regional alcohol sales rules rather than a single national curfew. The 17 autonomous communities each set their own hours — Madrid, Catalonia, the Balearic Islands, Valencia, and Andalusia typically prohibit retail alcohol sales from 22:00 (or 23:00) to 08:00 or 09:00, with stricter rules on petrol-station sales (often a flat ban on spirits 22:00–07:00). Some communities (Galicia, Asturias) are slightly more permissive; others enforce additional rules in tourist zones.

The legal drinking age across Spain is 18. Bars, restaurants, and night venues are licensed separately and have their own closing times — typically 02:00–03:00 in most cities, with later closing in designated nightlife districts. Many municipalities additionally restrict drinking in public (the ley antibotellón) outside licensed premises. If you need exact hours for a specific city, check the local ayuntamiento or comunidad autónoma rules.

Your liver does most of the work of breaking alcohol down, using enzymes to process it at a steady, limited rate. When you drink more than the liver can comfortably handle, the by-products of that process damage liver cells over time. This is why heavy or regular drinking is so closely linked to liver disease — and why alcohol is one of the leading preventable causes of mortality in Spain.

Alcohol-related liver damage usually develops in stages. The first is fatty liver disease (esteatosis), where fat builds up in the organ — often with no symptoms and partly reversible if you stop drinking. Continued heavy drinking can lead to alcoholic hepatitis (inflammation) and, eventually, cirrhosis, where healthy tissue is permanently replaced by scarring. Cirrhosis cannot be reversed. The Ministerio de Sanidad recommends staying under 2 UBE/day for men, 1 UBE/day for women, and including alcohol-free days.

Drinking heavily over many years raises the risk of a wide range of serious health problems. Alcohol contributes to high blood pressure, heart disease, and stroke, and to lasting liver damage. It is also a recognised cause of several cancers — including cancers of the mouth, throat, oesophagus, breast, bowel, and liver — and there is no completely "safe" level that removes this risk entirely. The WHO classifies alcohol as a Group 1 carcinogen.

The effects are not only physical. Long-term drinking is linked to depression, anxiety, and memory and concentration problems, and can lead to alcohol dependence, which is hard to break without support. It can also strain relationships, work, and finances. Spain's low-risk guideline — no more than 2 UBE/day for men, 1 UBE/day for women, with drink-free days — is designed to keep these long-term risks low. Cutting down at any age reduces your risk.

Blood alcohol content (BAC) has a direct effect on behaviour. At low levels (around 0.2–0.5 g/L), many people feel relaxed, more sociable, and more talkative, while their judgement is already slightly impaired. As BAC rises, those changes deepen — and they happen before you necessarily feel "drunk".

Above roughly 0.5 g/L (the Spanish legal limit for regular drivers), coordination, balance, and reaction time are clearly affected, self-control drops, and decision-making becomes poorer. Higher still, mood can swing quickly, inhibitions fall away, and the risk of accidents and of aggressive or regretted behaviour climbs sharply. Because alcohol weakens judgement, people routinely underestimate how impaired they are. Checking your estimated BAC with the calculator gives you an objective figure rather than relying on how in-control you feel.

Sertraline is a widely used SSRI antidepressant, sold in Spain under brand names such as Aremis, Besitran, and the generic sertralina. Standard medical guidance is that you can drink alcohol while taking sertraline, but it may make you feel drowsy, dizzy, or less alert. Because of this, it is often best to avoid alcohol for the first few days of treatment, until you can see how the medicine affects you.

There are good reasons for caution beyond drowsiness. Alcohol is itself a depressant, so it can worsen the low mood and anxiety the medication is prescribed to treat, and may blunt how well the treatment works. The combined sedative effect of alcohol and sertraline also makes activities such as driving especially risky — and in Spain, that effect can push you over 0.5 g/L on amounts you would normally consider safe. If you take sertraline, do not assume your alcohol tolerance is unchanged. For advice tailored to your medicine and dose, speak to your médico de cabecera or pharmacist.

It can be hard to tell when drinking has tipped from a habit into a problem, partly because it often develops gradually. Common warning signs include a strong or constant urge to drink, struggling to control or stop once you start, needing more alcohol to get the same effect, and drinking to cope with stress, anxiety, or low mood.

Other signs are the knock-on effects: drinking that interferes with work, relationships, or responsibilities, neglecting other interests, feeling guilty about how much you drink, or experiencing withdrawal symptoms — such as sweating, shaking, or irritability — when you do not drink. Noticing one or two of these does not mean the worst, but it is a good reason to take stock.
