If you’ve been driving through U.S. cities and towns, you’ve likely noticed an increase in roundabouts replacing traditional four-way intersections. Some drivers embrace them as an efficient traffic solution, while others find them confusing or even intimidating.
But what exactly is a roundabout, and why is it becoming a preferred alternative to stop signs and traffic signals? Roundabouts are not just about traffic flow—they are a safer, more efficient, and environmentally friendly way to design roads.
Let’s break down what roundabouts are, how they work, and why they are considered one of the most effective traffic management solutions today.
What is a Roundabout? Understanding the Basics

A roundabout—also known as a rotary or traffic circle—is a circular intersection where vehicles move counterclockwise around a central island. Unlike traditional intersections controlled by stop signs or traffic lights, roundabouts operate using a yield-at-entry system, meaning:
✔ Drivers entering the roundabout must yield to vehicles already circulating.
✔ Traffic flows continuously, reducing congestion and unnecessary stops.
✔ Speeds are naturally reduced, leading to safer driving conditions.
Most roundabouts also include:
🔹 Splitter islands – Raised medians that help slow down traffic before entering.
🔹 Pedestrian crosswalks – Positioned away from the central island to increase safety.
🔹 Lane markings – Clear indicators help guide drivers into the correct exit lane.
The result? A smoother, safer, and more efficient intersection that reduces both traffic delays and accidents.
A Brief History of Roundabouts
Many people assume roundabouts are a modern innovation, but their history dates back hundreds of years.
Video : Roundabout Safety Benefits
- 1700s – Early versions of circular intersections appeared in Europe, particularly in England and France.
- 1800s-1900s – Washington, D.C. was designed with multiple traffic circles, inspired by European models.
- 1950s – The United Kingdom introduced the yield-at-entry rule, transforming roundabouts into the efficient system we use today.
- 1990s – The first modern roundabout in the U.S. was built in Summerlin, Nevada in 1990.
- Today – Over 10,000 roundabouts exist in the United States, with more being installed every year.
While roundabouts have been common in Europe and Australia for decades, the U.S. is now rapidly adopting them due to their proven safety and efficiency benefits.
Why Roundabouts Are Safer Than Traditional Intersections
One of the biggest reasons cities are replacing traditional intersections with roundabouts is safety.
1. Fewer Conflict Points = Fewer Accidents
A typical four-way intersection has 32 conflict points—areas where vehicle paths cross, increasing the risk of collisions. In contrast, a roundabout reduces conflict points to just 8.
This means:
✔ No head-on collisions
✔ No dangerous T-bone crashes
✔ Fewer high-speed impacts
According to the Federal Highway Administration (FHWA), roundabouts can reduce serious and fatal crashes by up to 90% when replacing a stop-controlled intersection. Even when replacing a traffic signal intersection, they reduce serious crashes by nearly 80%.
2. Lower Speeds = Less Severe Collisions
In a roundabout, vehicles enter and exit at lower speeds (15-25 mph), compared to the higher speeds (40-50 mph) seen at traditional intersections.
Lower speeds lead to:
✔ Less severe crashes
✔ Fewer pedestrian injuries
✔ Easier decision-making for drivers
3. Safer for Pedestrians and Cyclists

Roundabouts offer better protection for pedestrians because:
✔ Crosswalks are set back from the circular flow, allowing drivers to see pedestrians clearly.
✔ Pedestrians only cross one direction of traffic at a time, making crossings safer.
✔ Cyclists can either merge into traffic or use a designated bike path, depending on the design.
With these safety features, roundabouts significantly reduce pedestrian-related accidents compared to traditional intersections.
Efficiency: Why Roundabouts Improve Traffic Flow
Beyond safety, roundabouts are also more efficient than stop signs or traffic lights.
1. Less Waiting, More Moving
At a traditional intersection, cars must stop at red lights, even when there’s no cross traffic. In a roundabout:
✔ Traffic keeps moving – No unnecessary stops.
✔ Fewer backups – No long wait times during rush hour.
✔ Reduced driver frustration – No more waiting for a green light when there’s no oncoming traffic.
2. Eliminating Left Turns = Smoother Flow
One of the most dangerous and disruptive movements at an intersection is the left turn. Roundabouts eliminate left turns, forcing all vehicles to move in the same direction, improving:
✔ Traffic efficiency – No waiting for gaps in oncoming traffic.
✔ Driver decision-making – No confusion about when to turn.
3. Roundabouts Handle High Traffic Volumes Better
Unlike stop signs and traffic lights, which cause congestion during peak hours, roundabouts allow continuous movement, making them ideal for high-traffic areas.
Environmental Benefits: How Roundabouts Help the Planet

Roundabouts aren’t just safer and more efficient—they also have environmental advantages.
1. Reduced Fuel Consumption
✔ Less idling at red lights = less wasted fuel
✔ Lower speeds = better fuel efficiency
According to studies, roundabouts can reduce fuel consumption by up to 30%, making them a cost-effective solution for drivers.
2. Lower Carbon Emissions
Fewer stops and starts mean lower emissions, helping reduce air pollution in urban areas. Cities that replace signalized intersections with roundabouts see:
✔ Less smog and pollution
✔ Improved air quality
3. Less Road Maintenance Required
✔ No traffic signals = lower maintenance costs
✔ Roundabouts last longer than traffic lights
With less infrastructure to maintain, roundabouts save cities money in the long run.
Challenges: Why Some Drivers Struggle with Roundabouts
Despite their many benefits, some drivers remain hesitant about roundabouts. Common challenges include:
🚦 Confusion about yielding – Some drivers don’t understand that they must yield to circulating traffic before entering.
🚦 Merging issues – Drivers unfamiliar with roundabouts sometimes hesitate, causing unnecessary slowdowns.
🚦 Exit mistakes – Some drivers find it difficult to choose the correct exit and miss their turn.
However, studies show that once drivers become familiar with roundabouts, their confidence improves significantly.

Final Thoughts: Are Roundabouts the Future of Road Design?
Roundabouts are more than just a traffic trend—they are a safer, smarter, and greener solution for modern transportation. With their ability to reduce crashes, improve traffic flow, and lower emissions, they are quickly becoming a preferred alternative to traditional intersections.
🚗 Safer roads, fewer accidents
🚗 Smoother traffic, less congestion
🚗 Lower fuel costs, reduced pollution
As more states adopt roundabouts in urban and suburban planning, they will likely become a permanent feature of America’s roadways.
So next time you approach a roundabout, embrace the change—it’s making our roads safer and more efficient for everyone!
DWTS Viewers Furious About This Contestant’s Sparkly Ankle Bracelet – See the Drama Unfold

Fans of *Dancing with the Stars* are upset after one of the dancers performed a mediocre cha cha while wearing a sparkly bracelet on her right ankle. What seemed like a simple accessory actually had a deeper meaning.
Despite the backlash, the dancer stood her ground, telling the quiet audience, “I’ve reinvented myself many times” and “this time I’m going to be a ballroom dancer.”
Keep reading to find out who this controversial performer is on the popular TV show!
Ezra Sosa faced a big challenge in season 33 of *Dancing with the Stars*, his first season as a professional dancer.
His partner claimed to have dance experience, but Ezra had his doubts. When asked about her background, he said, “She did ballet and modern,” then laughed and added, “I don’t think she did…”
Like many others, Sosa doesn’t fully trust what his partner says.
His partner, known as a “fake heiress,” was convicted of grand larceny after pretending to be a wealthy German heiress. She scammed many socialites and even some banks and hotels while living in New York.

Sosa’s partner is Anna Sorokin, who is also known as Anna Delvey. She was born in Russia and became famous after her crimes inspired the Netflix show *Inventing Anna*.
Delvey gained attention for defrauding people, banks, and hotels. The Netflix series features her story, with actress Julia Garner playing her role.
She was convicted of grand larceny multiple times in 2019 and was released from prison in 2021 for good behavior. However, after breaking the rules of her Visa, she was taken into custody by U.S. Immigration and Customs Enforcement (ICE) and placed under home confinement.
Now considered a flight risk, she wears an ankle monitor while she fights to stay in the U.S. and avoid being deported back to Germany, where she is a citizen.
On September 17, Anna caused a lot of controversy with her appearance on the first episode of the new season of *Dancing with the Stars*.

After Delvey was introduced as a “fashionista and entrepreneur,” she and Sosa took to the dance floor to perform a cha-cha to Sabrina Carpenter’s song “Espresso.”
They wore colorful outfits in shades of blue, purple, pink, and yellow. Delvey added a sparkly ankle monitor to her look.
During their performance, Delvey explained her unusual accessory, saying, “I overstayed my visa because I was in jail, so it’s kind of hard to leave.” She laughed and added, “I did serve my time… I’ve reinvented myself many times, and this time I’m going to be a ballroom dancer.”
The judges praised Anna Delvey’s efforts and expressed their surprise at her performance.
Derek Hough said, “I’m kind of lost for words. You actually have the ability to be a really beautiful dancer. Truly, you really do… I was surprised.”
Bruno Tonioli added a more playful touch, saying, “Reinventing Anna … yet again! And it could be working!”
Carrie Ann Inaba addressed the unusual silence in the studio, saying, “When you came out on the dance floor, there was a shift in the energy in this room. I imagine this is scary for you, and I’m not for or against anything you’ve done. But this is about your dancing here.”
However, fans were less kind. Many criticized her “robotic” moves and “miserable face,” while others were upset about the ankle monitor.
“Ankle monitors are not iconic. She should not be on this show,” wrote one user on DWTS’s Instagram page. Another added, “Felons should not be given any sort of spotlight.”
One commenter took issue with her title, saying, “Ooof. ‘Fashionista and entrepreneur?’ No… criminal.” On the DWTS Facebook page, another fan expressed, “Let’s glamorize an ankle bracelet. I’m disgusted.”
