Kernrechtsfrage
Whether the cantonal duty to identify the driver violates the privilege against self-incrimination under Article 6 ECHR.
Extrahierter Entscheid
The duty is compatible with Article 6 ECHR insofar as the person summoned may refuse to answer when disclosure would incriminate themselves or close relatives; a blanket refusal without explanation remains punishable.
Extrahierte Begründung
The Court distinguished coercive measures that force production of incriminating evidence from a witness-style request for information. It held that the Geneva provision can be read in light of the cantonal procedural rule allowing refusal on self-incrimination grounds, so the privilege is preserved. The appellant gave no such reason and simply failed to answer at all.
