If you are both turning left and facing each other, or if you are both going straight and facing each other, you may be able to go at the same time as long as you know the other driver is going to follow through. Use caution and make sure the next move is obvious. Hesitate if necessary.
这是BC省的交规,说的很明白了。
1,如果面对面,如果你能确认对方是直行,一起通过没问题
2,如果都左转,需要非常小心确认安全,必要时停下
我一直再说,单车道4面停牌没有两辆车同时左转的物理空间,就是位置不够,两辆车左转会撞上,所以从实际操作上来说不能同时进行左转。
