Alcohol Limits in Sweden
Sweden’s legal blood-alcohol limit is 0.2 ‰ (per mille) — among the lowest in the world.
- 0.0–0.2 ‰ — legal, but alcohol is never entirely without effect
- 0.2–1.0 ‰ — drink driving (rattfylleri) — fine and licence suspension
- 1.0 ‰ and above — gross drink driving (grovt rattfylleri) — criminal prosecution, prison possible
One standard drink raises blood alcohol by roughly 0.15–0.25 ‰ in an average adult — meaning even one beer can put you close to or over the limit.
What Alcohol Does to Driving
- Slows reaction time — even at 0.5 ‰ reaction time increases by 20–30%
- Narrows field of vision (tunnel vision)
- Reduces ability to judge speed and distance
- Increases risk-taking and reduces self-awareness
- Causes drowsiness — especially dangerous on long journeys
Drugs and Medicines
Many prescription and over-the-counter medicines affect driving — antihistamines, sleeping pills, strong painkillers and some antidepressants. Always check the patient information leaflet. Illegal drugs are treated the same as alcohol under Swedish law, often with lower detectable thresholds.
Driver Fatigue
Fatigue is involved in approximately 20–30% of fatal road crashes. Warning signs that you are too tired to drive:
- Frequent blinking or heavy eyelids
- Difficulty keeping the car in lane or at steady speed
- Missing exits or not remembering the last few kilometres
- Head dropping or micro-sleeps
- Yawning repeatedly
What to Do When Tired
The only reliable fix is sleep. If you need to reach a safe stopping point:
- Pull over and take a 20-minute nap
- A strong coffee gives about 30 minutes of improved alertness — take the nap while waiting for caffeine to kick in
- Open windows and loud music delay fatigue by only minutes — they are not solutions
Key Takeaways
- Sweden’s limit is 0.2 ‰ — stricter than most of Europe
- Even one drink can push you over
- Prescription drugs can also impair — check the label
- Fatigue is as deadly as alcohol — the only cure is sleep
