Sweden enforces some of the strictest drink-driving regulations in Europe. This article breaks down the legal alcohol (promille) limits for drivers, the definitions and penalties for 'rattfylleri' (drink-driving) and 'grovt rattfylleri' (severe drink-driving), and the impact on your driving licence. Understanding these critical rules is essential for safe driving and passing your theory exam.

Driving under the influence of alcohol is one of the most significant risks on any road, and Sweden enforces some of the strictest regulations in Europe to combat this danger. For anyone preparing for their Swedish driving licence theory exam, a thorough understanding of these laws, the legal promille limits, and the severe consequences of violations is not just recommended, but absolutely essential for safe and responsible driving. This article will delve into Sweden's approach to drink-driving, defining key terms like 'rattfylleri' and 'grovt rattfylleri', explaining the legal alcohol limits, and outlining the profound impact these violations can have on your driving privileges and future.
Swedish traffic law takes a zero-tolerance approach to impaired driving, with clear legal limits defining when a driver is considered unfit to operate a vehicle. The primary measure used is the blood alcohol content, expressed in promille (‰). This unit represents grams of alcohol per kilogram of blood. Understanding these thresholds is fundamental to safe driving practices and passing your theory test.
The general legal limit for blood alcohol content in Sweden for most drivers is 0.2 promille (‰), which equates to 0.1 milligrams of alcohol per litre of exhaled air. Exceeding this limit, or being in a state where your driving ability is demonstrably impaired by alcohol, constitutes 'rattfylleri'.
Driving a motor vehicle with a blood alcohol content of 0.2 promille or more, or being otherwise significantly impaired by alcohol, drugs, or other substances to the extent that it affects your driving ability.
However, for new drivers and those under a certain age, the rules are even more stringent. Sweden has a 'zero-tolerance' policy for new drivers during a probationary period.
A special rule for new drivers where they are not permitted to have any alcohol in their blood while driving. This period typically lasts for two years after obtaining a driving licence, and also applies to drivers under the age of 21, even if they have held their licence for more than two years.
This means that if you are a new driver or under 21, any detectable amount of alcohol in your system while driving can lead to penalties. For all other drivers, the limit is 0.2 promille, but it is crucial to remember that even below this limit, if your driving is deemed unsafe due to alcohol consumption, you can still be charged with rattfylleri.
When the blood alcohol content reaches significantly higher levels, or when the driver is markedly affected by alcohol or other substances, the offence is classified as 'grovt rattfylleri' (severe drink-driving). This is considered a far more serious transgression due to the substantially increased risk to public safety.
The threshold for grovt rattfylleri is a blood alcohol content of 1.0 promille (‰) or higher. This is equivalent to 0.5 milligrams of alcohol per litre of exhaled air. Individuals found to be driving with this level of alcohol in their system are considered a grave danger to other road users.
Driving a motor vehicle with a blood alcohol content of 1.0 promille or more, or being otherwise markedly impaired by alcohol, drugs, or other substances to the extent that it poses a significant danger to road safety.
The penalties associated with grovt rattfylleri are significantly more severe than those for standard rattfylleri, reflecting the heightened risk involved.
The penalties for violating Sweden's drink-driving laws are substantial and can have long-lasting repercussions on your life, extending far beyond immediate fines. These consequences are designed to deter potential offenders and protect the public.
A conviction for rattfylleri typically results in a fine and, in most cases, the revocation of your driving licence. The duration of the licence suspension is usually 12 months, but can be extended if there are aggravating circumstances or if the offence is repeated. In some instances, a prison sentence of up to six months may be imposed. It is important to note that the term 'rattfylleri' applies not only to alcohol but also to driving under the influence of drugs or certain medications that impair your driving ability.
The consequences for grovt rattfylleri are more severe. Conviction typically leads to imprisonment, with sentences ranging from a few months up to two years. Furthermore, the driving licence will be revoked for a longer period, usually up to 24 months. In extremely serious cases, particularly if the severe drink-driving offence has led to an accident causing death or serious injury due to negligence, the prison sentence could extend up to eight years.
A crucial point to remember for your theory exam is that even if your blood alcohol content is below the legal limit, you can still be prosecuted for 'rattfylleri' if the police assess that you are not in a fit state to drive safely. This could be due to erratic driving, involvement in an accident, or a general inability to operate the vehicle competently.
The revocation of a driving licence is a common outcome for both rattfylleri and grovt rattfylleri. Re-obtaining a licence after a revocation often requires passing both the theory and practical driving tests again, and sometimes requires undergoing additional medical assessments. For new drivers who have their licence revoked during their probationary period, the implications can be particularly significant, often requiring them to re-apply for a learner's permit and start the licensing process anew.
Swedish law makes it clear that it is prohibited to drive any motor vehicle if you are under the influence of alcohol, drugs, or any other substance that impairs your ability to drive safely. This encompasses not only illegal narcotics but also prescription and over-the-counter medications.
The Swedish Transport Agency and Trafikverket emphasize a "zero tolerance" policy towards illicit drugs in traffic. Not even the slightest trace is permitted if it renders you unfit to drive. However, there are exceptions for prescribed medications. If a doctor has prescribed a narcotic substance or other medication, it is permissible to drive provided that the medication does not make you a danger on the road. It is your personal responsibility, with the help of your doctor, pharmacist, and the medication's package insert, to assess whether a prescribed drug will impair your driving ability. Driving while impaired by such medications can lead to charges under the rattfylleri laws.
Various types of drugs can affect driving ability in different ways:
Even common medications such as sleeping pills, sedatives, and some allergy medicines can affect your cognitive functions and reaction times, making it unsafe to drive. Always consult with your doctor or pharmacist if you are unsure about the effects of any medication.
When preparing for your theory exam, pay close attention to questions involving medications and driving. The key principle is always whether the substance makes you unfit to drive, regardless of whether it was prescribed or obtained legally.
As previously mentioned, new drivers in Sweden are subject to a stricter noll-promille (zero-tolerance) law for the first two years after obtaining their licence. This rule applies irrespective of age. It also extends to drivers under 21 years of age who have held their licence for more than two years. This stringent policy underscores Sweden's commitment to ensuring new drivers develop safe habits from the outset, free from the influence of alcohol. Violating this noll-promille rule will result in penalties, including fines and a mark on your driving record, and potentially licence revocation if the violation is severe or repeated.
The legal limits and severe penalties are in place because driving under the influence poses an extreme risk to oneself and others. The impairment caused by alcohol or drugs affects critical driving skills such as judgement, reaction time, coordination, and vision. Even small amounts can significantly reduce your ability to respond safely to unexpected events on the road.
It is crucial to internalise the message that "if in doubt, don't drive." Factors like body weight, metabolism, food intake, and even gender can influence how alcohol affects an individual. Therefore, relying on anecdotal advice or personal estimations of sobriety is dangerous and ill-advised. Always err on the side of caution. If you have consumed any alcohol or taken any medication that could impair your ability to drive, it is always best to leave the car parked and arrange for alternative transportation, such as a taxi or public transport, or have a sober designated driver.
The Swedish Transport Agency (Transportstyrelsen) and Trafikverket strongly advocate for a responsible approach to driving, prioritising safety above all else. This includes making informed decisions about alcohol and medication consumption and their potential impact on your ability to drive safely.
