When one thinks of road factors that cause crashes, especially in North Dakota, the first thing that tends to come to mind is harsh weather and while icy roads and freezing temperatures can indeed cause problems, there is another threat that can lead to fatal accidents any time of year: poorly-maintained roads. A lack of proper construction, obscred markings, and inadequate signage can lead to disaster when drivers are not prepared for unexpected situations. and as a new study shows, this is especially problematic in the Peace Garden State.
