The roadworks series starts with the "roadworks ahead" triangle and then moves to lane closures, barricades, diversions and works-traffic signs. Many of them are red rectangles with white text in Arabic and English, and a few use a yellow panel.
For the other hazards you will meet on the road, see warning signs.
