Dangerous intersections in West Virginia could be made safer if roundabouts are installed instead of stop signs or traffic lights. According to studies by the United States Department of Transportation, roundabouts reduce serious and fatal accidents by 78 to 82 percent. A serious motor vehicle accident, also known as an "A" accident, is defined as an accident that causes broken bones, massive loss of blood or unconsciousness to occur.
Though traffic lights have been found to reduce the number of vehicle crashes overall, the accidents that do occur at traffic lights are often more serious. This is especially true when there are intersections on roads with high speed limits. Roundabouts force drivers to slow down, which reduces the severity of the collisions.
