But what does the law say?

In Sweden we have limits for drinking and driving, and also the length of the penalties based on the crimes that are made.
The police, car inspectors and the workers of the coast guard has the right to perform breath tests on people on the road.
 
How do these work though?
A temperance traffic control step by step will be shown here below. The first step in the traffic temperance control is that the driver blows into a so-called screening instruments. The said instrument gives a reading on the breath alcohol and if it crosses the limit. If it does, the next step is to provide a breath sample in a proof instrument called ”Evidenzer”.
The suspect may then blow twice in the proof instrument with 6-8 minutes intervals. This usually takes place in a police station or a police van. From the two exhalations in the instrument, the instrument will start counting out a mean of alcohol in the breath. The average value is used as the basis for a court order of punishment and driver’s license revocations.
 
The highest BAC you can have before you pass the limit for driving drunk is 0.2, which corresponds to 0.10 milligrams of alcohol per liter of exhaled air. If you pass the limit of 0.16 milligrams of alcohol per liter of breath you may get your license taken for care. The penalty aren’t too rough, it can go from getting a ticket to going to jail but not exceeding six months.
 
The limit for rough drunk driving is 0.50 milligrams of alcohol per liter of exhaled air, which corresponds to 1.0 per thousands in the blood. Although intoxicated drivers who meant a considerable danger to the road can still be convicted of rough drunken driving even if they haven’t reached the limit.
The penalty for this is to be imprisoned for not more than two years. These rules does not only imply for car drivers but also for boat drivers and the others.
 
The limit for heavy marine intoxication is 0.5 milligrams of alcohol per liter of exhaled air, which corresponds to about 1.0 per thousands in the blood. Even an affected skipper who brought a considerable hazard to maritime safety can be sentenced for heavy marine intoxication, even if the limit is not reached.
The penalty for rough intoxication gives imprisonment for not more than two years.
