Spain’s top traffic official confirms that Madrid and Barcelona city halls have formally requested a drastic reduction in the legal blood alcohol limit for drivers. The move could make even a single beer enough to trigger a positive test.
Spain’s two biggest cities want a major change. Madrid and Barcelona have formally asked the Dirección General de Tráfico (DGT) to lower the legal blood alcohol limit for drivers to almost zero. Pere Navarro, who leads the DGT, said both city councils and the Federación Española de Municipios y Provincias are pushing for 0,0 alcohol drinks and much tighter checks on drivers.
The government is now looking at a plan to cut the maximum blood alcohol level from 0.5 grams per litre to 0.2 grams. For breath tests, the limit would fall from 0.25 to 0.1 milligrams per litre. The draft law does not set the limit at a true zero, but Navarro made it plain: even one beer could now put a driver over the line. Official figures from the Congreso de los Diputados show the lower house approved the first reading of this reform on September 29, 2026. The vote was close: 173 in favor, 168 against, and 5 abstentions.
Current Spanish law sets the general blood alcohol limit for drivers at 0.5 g/l, with stricter thresholds for novice and professional drivers, and a zero limit for underage drivers.
Navarro stressed this is not just a local push. "All the experts recommend it, we follow the recommendation of the WHO and the European Commission," he said. He pointed out that countries like Norway and Sweden already use these stricter limits. The World Health Organization recommends a 0.2 gr/l threshold. Navarro called this "tolerance zero."
But there is a reason the law does not set the limit at a perfect 0,0. Some foods and cooking methods can leave tiny traces of alcohol in the body. A small margin is needed so drivers are not punished unfairly. Still, the message is simple. Any alcohol before driving is now a risk. Several Spanish media outlets have reported that the law is still under review in parliament. It will not take effect until it is fully approved and published in the official state bulletin (BOE). If passed, the new limits could start two months after publication.
This is not the first time Spain has debated drink driving limits. The current reform is part of a bigger shift in how the country thinks about road safety. The latest changes to the Reglamento General de Circulación took effect on October 1. The law now focuses more on people and city life, not just cars and roads. For the first time, "vulnerable road users" are defined. This group includes pedestrians, cyclists, motorcyclists, users of personal mobility vehicles, children, the elderly, and people with disabilities.
The current legislative push is not the first attempt to lower Spain's alcohol limits for drivers; a similar proposal was previously rejected in committee, making this a renewed effort to advance the same idea.
The DGT wants to cut alcohol limits and protect these groups. The goal is fewer and less severe road accidents in Spanish cities. The changes show that city travel has changed a lot in the last 20 years. New rules are needed. Public health matters.
Spain is finally moving to match international best practice on drink driving. Madrid and Barcelona are leading the charge for stricter limits. The country is putting safety first. The real question is whether these rules will mean fewer crashes and a real change in attitudes about drinking and driving. For now, the direction is clear. The days of tolerance for alcohol at the wheel in Spain are ending.
