Kernrechtsfrage
Whether the defendant acted negligently when performing a U-turn after the signal turned yellow.
Extrahierter Entscheid
Yes. Even if a left turn remained permitted, the U-turn was a risky maneuver requiring reduced speed and heightened caution; the defendant had to expect imminent opposing traffic and not impede other road users.
Extrahierte Begründung
A U-turn is slower and more unusual than a left turn, may create uncertainty for other drivers, and on the facts the defendant could no longer safely complete it once the light changed to yellow; he also failed to remain sufficiently attentive.
