Question

DentroTest · Accepted Answer

All drivers are required to undergo alcohol detection tests (General Traffic Regulations, Article 21), and traffic surveillance officers may require them in several situations: being possibly directly responsible for an accident, driving with obvious symptoms of being under the influence of alcohol, having been reported for some offense against the traffic rules, or being required at a preventive alcohol checkpoint ordered by the authority. That is why the test may be required at any time if any of those situations arises. Limiting it to the direct cause of an accident or to someone already reported is wrong, because it leaves out the other situations provided for.
