When your view is blocked, you can’t accurately judge whether a vehicle, bicycle, or pedestrian is approaching the intersection. That lack of visibility creates a real risk of a collision if you turn. The safe course is to wait until you have a clear view before proceeding. This often means stopping at or before the intersection and, if needed, edging forward only enough to see past the obstruction to check for oncoming traffic and pedestrians. Traffic being light or having a green arrow does not justify turning if you can’t see well enough to ensure it’s safe. Only when you can see clearly and confirm it’s safe should you proceed with the left turn.
