你没考过交规吗？

Stop Sign 咋操作？You must come to a full stop, then proceed when safe.

就算在Stop Sign 停住了，出路口时让直行的车撞了，还是这个车的责任。

此外，AZ相关的左转的交规：

“T” Intersections: At a “T” intersection, the driver on the street which ends must yield the right-of way to vehicles on the cross street。

Left Turn： When you are preparing to turn left, you must yield the right-of-way to any oncoming vehicle and pedestrian.

你这种抬杠真是无聊。好好读交规去。
