Drink Driving in Spain: Margins of Error in Breathalyser Tests

While the penalty for drink driving in Spain can lead to imprisonment, in practice (first offence, no criminal record) this is very unlikely.

Drink Driving in Spain Margins of Error in Breathalyser Tests

Punishments available to the Courts

Article 379.2 of the Spanish Criminal Code states that anyone who drives a motor vehicle under the influence of toxic drugs, narcotics, psychotropic substances or alcoholic drinks shall be punished with a sentence of imprisonment for a period of between three to six months or with a fine for six to twelve months (at the specified daily rate).

Alternatively, drink driving in Spain may be punished by community service orders for 31 to 90 days and, in any case, with disqualification from driving motor vehicles for more than one year up to four years.

In any case, anyone will be punished if the  result of a breathalyser test shows an ‘exhaled  alcohol level’ of more than 0.60 milligrams per litre or an alcohol level greater than 1.2 grams per litre blood.

Different Types of Breathalyser

There are two types of breathalyser used by the police in Spain – one is a mobile design, used by the Police when out on patrol.

It is more rudimentary and less precise than the larger version that is used in Police Stations. This latter version is the definitive breathalyser and it is the results on this machine that are used to determine what action, if any, should be taken against a motorist.

So, in order for there to be a conviction for drink driving in Spain, the latter test must be carried-out. At this point is is worthwhile pointing out that the driver must submit to this test as a refusal will be considered a crime of disobedience.

Margin of Error

To the result obtained from a breathalyzer test we must apply a margin of error which will, therefore, reduce the result  – this can be calculated by performing a simple arithmetic operation.

If after applying margins of error, if the first test yields a rate greater than 0.65 mg Alcohol/litre breath but the second measurement result is lower, the police will prepare and submit a report to the judicial authorities that a crime has been committed because the driver, when tested, was driving, according to the primary test, with a rate higher than the rate provided for in Article 379.2, which will result in a fine only.

On the contrary, if after applying the above margins of error to the first test,  the  result is a reading of less than 0.65 mg of ethanol per liter of exhaled air and that reading is higher than the second reading, only an administrative complaint shall be made for such a breach.

In the interests of the accused and to guarantee the exclusion of any incorrect results, the legal limit has to be exceeded by both results because, otherwise, a person could be condemned although they had  not in fact exceeded the legal maximum.

Imprisonment

Although the penalty for drink driving can lead to imprisonment, in practice and reality in accordance with our legal system, a first offence, with no criminal record, does not involve imprisonment, even a second offence may not attract a prison sentence, though this is a matter left to the discretion of the judge. On the other hand, a third offence will normally be punishable with a custodial sentence.
If you find yourself involved in such situations, at any level, you probably will greatly benefit from asking for local expert help regarding Road Traffic Offences.

    We had a legal problem in Spain and the allocated solicitor, Consuelo, helped us solve the issue. Right from the beginning she was extremely professional and understanding of our needs. It was obvious that she knew exactly what was required.


    We felt completely at ease and presented very knowledgeable in respect of legal procedures. I would highly recommend the Advocate Abroad service to anyone in a tight spot in need of legal help.


    In terms of what could have been improved, maybe time from initial phone call requesting service to client contact could be a bit quicker, but that's the only thing.

    Initially I had a lot of communication but as time went on it was difficult to get prompt responses and I felt frustrated by the Spanish system and lack of understanding.


    It has now been transferred to the UK but this was done through the court and not the solicitor. it took 3 months for our file to turn up in the UK and I think that was more by luck.


    More regular communication especially as we didn't know the Spanish legal system.

    We have recently had to employ the services of a lawyer, to deal with a very serious and distressing problem. We found Alvero and made a phone call to him ,within seconds of speaking to him he proved to be the lawyer to represent us.


    His knowledge of our particular problem was in depth and precise he listened carefully and gave us really sound and honest advice. His professionalism in handling our case has been impressive to say the least but he has also remained sympathetic and constantly kept us up to date with everything he has been doing at every stage.


    This has helped to minimize the stress at this extremely stressful time I would have no hesitation in recommending Alvero. His professionalism and whole attitude towards his clients is second to none
