Warning signs
Warning signs are mostly red-bordered triangles with a black symbol on a white background. They tell you what to expect further along the road so that you can adjust your speed and position before you reach the hazard. A warning sign never gives an order on its own, but ignoring one usually leads straight into a situation where the rules do apply.
