Key legal question
Whether the cantonal court violated the presumption of innocence / in dubio pro reo by finding that the other driver had activated her right indicator.
Extracted holding
No. The court could rely on the interested driver's plausible statement and was not required to seek additional external proof.
Extracted reasoning
The presumption of innocence forbids conviction only where objective, serious and irreducible doubt remains. The cantonal court's acceptance of one plausible version of events was not arbitrary and the assessment was not untenable in its result.
