Roundabouts in Tennessee and other states act as a safety precaution that counteracts the dangers of a normal intersection. Roundabouts create a circular intersection that leads to a safer environment because vehicles must travel at lower speeds, and the devices also have operational advantages, reducing conflict.

The Federal Highway Administration recognized that signalized intersections have faults because one-third of intersection fatalities occur at these spots. About 2,300 people die each year due to these signalized intersection fatalities, and around 700 people die yearly due to collisions after a driver runs a red light.

Roundabouts reduce the amount of injuries and deaths resulting from intersection crashes. The rate of severe crashes drop 82 percent when a roundabout replaces a two-way stop control mechanism, and all motor vehicle accidents are reduced by 44 percent. The amount of crashes at previously signalized intersections are also reduced when a roundabout is used.

Roundabouts are an effective safety feature because they help manage speed and can serve as a transition from a high-speed area to a low-speed area. These safer intersections can be paired with a range of traffic conditions in rural and urban locales. Roundabouts might be best at rural high-speed intersections, freeway interchange ramp terminals, highway projects involving construction or when replacing an intersection with safety issues.

When otherwise preventable accidents take place because of the negligence of others, an injured party could be entitled to compensation for medical expenses. If a driver runs a red light at an intersection, he or she may be responsible for a car accident. If this occurs, the injured party may benefit from discussing their case with a lawyer who is familiar with personal injury lawsuits.
