Each year the Charlotte Department of Transportation produces a High Accident Location (HAL) list that ranks the intersections in Charlotte where crashes are most likely to occur. The list is computer generated and factors in volume of traffic, number of accidents and severity of accidents to determine the ranking. For more information, click on HAL FAQ.
