Spain's Blood Alcohol Limit for Driving: Administrative Fine vs. Criminal Offence (2026)

Spain regulates alcohol and driving on two entirely separate tracks. Below a certain point, an excess is a DGT fine, decided administratively, appealable through the usual ladder. Above it, the same conduct is a crime, decided by a judge, with prison on the table. This page draws that line precisely and shows what sits on each side of it.

The administrative limits

Art. 20 of the Reglamento General de Circulación (RD 1428/2003) sets three tiers. The general limit is 0,5 g/l in blood, or 0,25 mg/l in exhaled air. A lower limit, 0,3 g/l in blood or 0,15 mg/l in air, applies to drivers of heavy goods vehicles over 3.500 kg, buses with more than nine seats, public-service and school transport, dangerous-goods transport, and emergency or special transport. The same lower limit, 0,3 g/l or 0,15 mg/l, also applies to every driver during the first two years after obtaining a licence, regardless of what they are driving.

The administrative fine

An excess above the applicable limit is a muy grave infraction fined at 500 € (art. 77.c TRLTSV). It escalates to 1.000 € only in two situations: the driver was already sanctioned for an alcohol infraction within the previous year, or the reading is above double the permitted limit (art. 80 TRLTSV). Like most infractions, this fine still carries the 20-day, 50 percent pronto pago option, and the same appeal ladder covered on the appeals page.

Where it becomes a crime

Art. 379.2 of the Código Penal draws a hard line that has nothing to do with the DGT's administrative bands. Two routes into the crime exist. The first is a fixed, per-se threshold: driving with a reading above 0,60 mg/l in exhaled air, or 1,2 g/l in blood, is automatically a crime, regardless of how carefully or recklessly the person was actually driving. The second route does not depend on a number at all: driving under the influence of alcohol, toxic drugs, narcotics or psychotropic substances is independently criminal if impairment can be shown, even at a reading below the numeric threshold.

The penalties are the same for either route: prison of three to six months, or a fine of six to twelve months, or thirty-one to ninety days of community service, and in every case, loss of the right to drive for more than one and up to four years. There is a further consequence built into the Código Penal itself: a driving-ban sentence of more than two years does not just suspend the licence for its length, it ends the licence's validity outright (art. 47 CP), so a driver convicted at the higher end of the range comes out the other side needing a new licence, not a reinstated one.

The same administrative-versus-criminal split governs speed as well, at 60 km/h and 80 km/h over the limit, covered on the speeding fines page.

Points, separately from either fine

An administrative alcohol excess is one of the graves and muy graves that carries a point deduction on top of the money fine, the same parallel system that applies to most licence-affecting infractions. A criminal conviction does not use the points system at all; its consequence is the driving ban set by the sentence, not a deduction from the 12-point balance. The mechanics of how points are earned, lost and recovered are covered in full on the points page.

Refusing the test

Refusing a legally required alcohol or drug test is not a way to avoid the numbers, it is its own separate crime. Art. 383 CP punishes refusal with prison of six months to a year and a driving ban of one to four years, independent of what a reading would have shown had the driver taken the test.

Why the split matters

A DGT sanction is a fine plus, where applicable, lost points, decided administratively and challengeable through alegaciones, reposición and the contencioso-administrativo. A criminal case is a court proceeding that can end in a prison sentence or a criminal record, decided by a judge rather than the DGT, with driving bans that run far longer than any administrative suspension. The two systems track different things: the DGT tracks the reading and the licence, the criminal courts track the reading against a per-se threshold or actual impairment. Understanding which side of that line a case sits on is the difference between a fine and a defence lawyer.
