when crossing multilane highways, you should treat each side as a one way street.
I would say true.
If there is an island in the middle, cross one half of the highway at a time.
And nearly all US highways have an island in the middle.
I think Leo assumes that there is is enough space in the width of the island for a car to remain stopped without blocking traffic on either side. Only if this is true is his answer correct.
I hope this helps a little more. Thanks for asking.
