Roundabouts have been popping up all over North Georgia the past few years. Approximately 400 are in use or in planning stages across the state. We understand they can be confusing and hard to get used to, but the truth is, they are actually safer than traditional intersections.


Imagine a driver entering a two-lane roundabout in Buford, distracted by GPS directions. Instead of yielding to traffic already in the circle, they collide with another vehicle, leading to confusion over who’s at fault. This type of accident highlights the importance of understanding roundabout right of way rules and proper navigation techniques.


In the last decade, roundabouts have increasingly become a common sight in Buford, Flowery Branch, and other areas across Georgia. As a traffic solution, they are designed to improve the flow of vehicles and reduce the likelihood of serious crashes. However, many drivers remain uncertain about their effectiveness, especially when it comes to safety.


In this blog post, we’ll take a deep dive into how roundabouts affect car accidents, explore the benefits and challenges of roundabout design, and provide roundabout safety tips.



Understanding the Safety of Roundabouts

It’s natural to wonder: Are roundabouts safer than intersections? According to numerous studies, the answer is yes. Roundabouts are proven to reduce the risk of severe accidents significantly.


Research from the Insurance Institute for Highway Safety (IIHS) indicates that converting traditional intersections to roundabouts leads to a 72-80% reduction in injury-related crashes, and overall crashes decrease by 35-47%. This safety boost stems largely from the fact that roundabouts eliminate head-on and T-bone collisions, which are common in traditional intersections and often lead to severe injuries ​(IIHS Crash Testing) ​(Something About Orange).


However, roundabout car accidents still occur, often when drivers are unfamiliar with the rules or fail to yield properly. One of the key advantages of roundabouts is their ability to slow down traffic, which reduces the severity of accidents. But this benefit can be compromised if drivers don’t understand how to enter or exit the roundabout correctly. 


To reduce the likelihood of an accident, understanding roundabout safety tips is essential for all drivers, particularly in high-traffic areas like Buford and Flowery Branch.



Key Factors in Roundabout Car Accidents

Even though roundabouts are generally safer than traditional intersections, accidents do happen. One of the most common types of injury accidents in roundabouts in Georgia involves a failure to yield.


When approaching a roundabout, drivers must yield to vehicles already circulating within the roundabout. Failing to do so often leads to rear-end or sideswipe accidents, particularly in multi-lane roundabouts. These types of accidents, while often less severe than head-on collisions, can still result in injuries and damage.


Another contributing factor is driver confusion. Many Georgia drivers are still adjusting to the concept of roundabouts, and unfamiliarity with how they operate can lead to crashes. For instance, drivers may not know when to merge or change lanes within the roundabout. This is why it’s important to follow roundabout safety tips, such as always slowing down when approaching a roundabout and yielding to pedestrians and cyclists.


Roundabouts, particularly in rural areas where speeds can exceed 50 MPH, require extra caution. While they help reduce the likelihood of serious injuries, drivers should be aware that high speeds entering the roundabout can still lead to crashes.

Misunderstandings about how to properly navigate a roundabout, including failing to yield to traffic already in the circle, misjudging entry points, or not knowing when to exit, lead to collisions.


Single vs. Multi-Lane Roundabouts

There is a wide range of variation in safety between the single lanes and multi-lane roundabouts. Single lane roundabouts are thought to be the safest since they have fewer conflict points and less chance for driver confusion. Larger multi-lane roundabouts may be more difficult to cross and therefore often have higher accident rates.


One of the trade-offs involved in roundabout design is balancing the need for traffic flow with safety concerns. Multi-lane roundabouts allow for higher traffic volumes, making them ideal for busy areas or high-speed routes. However, they also introduce additional risks, such as lane-changing accidents. It’s crucial for drivers to understand how to safely maneuver within multi-lane roundabouts and to avoid switching lanes unless necessary.



Roundabout Safety Tips to Reduce Accidents

Following these simple safety tips can help reduce roundabout accidents and protect yourself and others on the road:


  1. Slow down before entering: Reduce your speed as you approach the roundabout. This gives you time to assess the traffic flow and choose the correct lane.

  2. Yield to traffic: Always yield to vehicles already in the roundabout. This is one of the most critical rules to follow and one of the most common causes of roundabout car accidents.

  3. Avoid lane changes inside the roundabout: Stay in your lane while navigating the roundabout. Changing lanes inside the circle can lead to sideswipe collisions.

  4. Watch for pedestrians and cyclists: Roundabouts are generally safer for pedestrians because they cross shorter distances, but drivers must always remain alert, especially in busy urban areas.

  5. Use your indicators: Signal your intent to exit the roundabout to alert other drivers and reduce confusion.



Common Roundabout Mistakes and How to Avoid Them

Mastering roundabouts starts with understanding their rules. Unfortunately, confusion often leads to accidents. Here are the most frequent common roundabout mistakes and how to avoid them:


  • Failure to Yield: Drivers entering the roundabout must yield to those already in the circle. Not doing so is the leading cause of roundabout accidents.

  • Improper Lane Usage: In multi-lane roundabouts, staying in your lane and signaling your exit are critical. Lane changes mid-roundabout often cause collisions.

  • Exiting Without Signaling: Failing to use your turn signal confuses other drivers, increasing the risk of side-impact crashes.

  • Speeding Through: Roundabouts are designed for slower speeds. Approaching too quickly can result in losing control or failing to stop in time.


Determining who is at fault on a roundabout can be complex. Factors like lane positioning, right of way, and speed all play a role in assigning fault, so it is essential to consult a qualified attorney. At The Edmonson Law Firm, we help clients investigate the circumstances of the accident, gather evidence, and navigate insurance claims and, if necessary, file a personal injury lawsuit it.




Conclusion

Roundabouts offer clear safety benefits over traditional intersections, reducing the likelihood of severe injuries and helping to keep traffic flowing smoothly. However, they still require caution and understanding, especially for drivers who may not be familiar with them.
