Yes. Police can require a breath test from anyone driving on a public road, anyone preparing to drive, a person accompanying a learner driver and people who may have been involved in a traffic accident.

Police may first use an alcohol-detection device or breath test. When the breath test reaches the applicable legal threshold, a more precise breath analysis is carried out to measure the alcohol concentration.

For ordinary drivers, a breath analysis is carried out when the breath test indicates at least 0.22 mg/l of alcohol in exhaled alveolar air. For drivers subject to the stricter professional limit, the threshold is 0.09 mg/l.

Yes. A blood test can be ordered in situations where the breath test or breath analysis cannot be carried out or in other circumstances provided by law.

Refusing a required breath test or breath analysis is itself punishable and also results in an immediate temporary prohibition on driving.

Since 1 July 2026, the standard immediate driving prohibition is 12 hours when the applicable alcohol threshold is reached or when the driver refuses the required test.

No. Before driving again, the person must undergo a new breath test or breath analysis. If the result remains at or above the legal threshold, or the person refuses the test, the prohibition is extended by another 12 hours.

When a breath analysis measures at least 0.35 mg/l, the person must be informed of the right to request a counter-analysis by blood test. The cost is borne by the person if the blood test confirms the offence.
