Police have caught 36 drivers over the alcohol limit and 9 more under the influence of drugs or similar substances. The figures are interim results from an Interior Ministry operation that is still under way.
The checks are held under the Road Traffic Act. They target drivers who have used alcohol or drugs, and those who drive without a licence.
Half of the drunk drivers, 18, had between 0.5 and 1.2 per mille of alcohol in their blood. The other 18 had more than 1.2. Four drivers refused an alcohol test and three refused a drug test.
Officers checked 15,348 vehicles and 18,088 drivers and passengers. They wrote 313 reports for administrative offences and issued 4,717 on-the-spot fines.
