Priority and yielding
Voorrang means priority. Voorrang verlenen means to give way or yield - you'll see this on triangular yield signs. Voorrangsweg means priority road - the road marked by a yellow diamond sign where you have priority at every junction.
Haaientanden means shark teeth - the white triangular yield markings painted on the road surface. If you see or hear this word, it refers to those triangles that determine who yields at a crossing.
