Key legal question
Whether the appellant negligently breached traffic duties when moving right after shifting left to enter a driveway.
Extracted holding
Yes. He had to check immediately before moving right that no vehicle was overtaking on the right; signaling and an earlier mirror check were insufficient.
Extracted reasoning
Under traffic rules and the principle of trust, a driver who creates a confusing or dangerous situation must take special precautions. A right-overtake was foreseeable in these circumstances, so the appellant had a duty to verify the right side and yield if necessary.
