A broken white line marks the road's centre. If the line becomes longer with shorter gaps, it warns of a nearby hazard. For example, while driving on a rural road, you notice the broken white lines on the road centre become longer with shorter gaps. This indicates a sharp bend ahead, so you stay in your lane to navigate the bend safely.
