شکل و رنگ

White rectangular plate with two black arrows pointing down-left and down-right: the sign applies on both sides of the post.

تابلو کجا نصب می‌شود

Directly under an E sign, on the same post, in the middle of the stretch the sign covers.

آزمون درباره‌ی این تابلو چه می‌پرسد

The question is over which stretch the sign applies: the arrows pointing down-left and down-right say the sign works both ways, so the parking ban or parking facility applies to the left and right of the post along the road. A single arrow would mark the start or end. Trap: candidates read the arrows as 'driving direction'.
