Do you have any ideas about the answer? A good hint is to think about Brewster's angle.

Well, when the incident angle is the Brewster's angle, the polarisation of the reflected ray is parallel to the interface.

In this case, imagine a sun ray hitting the road, which is horizontal. Then, the reflected ray will also be polarised horizontally. That is the type of rays you would like to block. Can you see the answer now?
