Kernrechtsfrage
Whether X. committed a priority violation by entering the main road despite seeing Y.'s vehicle in the mirror
Extrahierter Entscheid
X. could not rely on the trust principle; because the situation seen in the mirror was unclear, he had to stop and ensure a sufficient safety margin.
Extrahierte Begründung
Mirror perception makes distances and speeds difficult to assess, especially while moving. Since X. saw an approaching vehicle, he had to stop before entering the priority road.
