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!
My Father-in-Law Humiliated a Waiter, but Karma Struck When He Least Expected It
Greed led my father-in-law to cause a ruckus in a restaurant, leaving tension and strife in his wake. However, little did he know that his ego was about to be humbled when an unexpected twist arose from the karma of his actions. What started as a man trying to get his way turned into him learning a valuable life lesson that had continually eluded him.
At the risk of sounding overly dramatic, I’ve always believed in karma. You know, the idea that what goes around, comes around. But never in my wildest dreams did I expect to witness it unfold so vividly and immediately as it did one evening with my father-in-law (FIL), Benjamin.
This man, bless his heart, operates under the assumption that the universe, with all its cosmic might, revolves around him and is essentially supposed to cater to all his needs and wants. And on this particular day, karma decided to give him a reality check.
Let me paint the picture: My husband, Sam, and I, Linda, were dining out with him at a local restaurant Benjamin claimed to be the “best in the state.” He’s the kind of guy who orders as if preparing for an impending food shortage—four burgers, fries, the works!
As our patient waiter returned to the kitchen after bringing us our food, my FIL discreetly set aside one burger, a minor detail that would later unravel into an epic tale of instant karma.
We watched in shock as Benjamin erupted like a volcano at the returning waiter, disbelief and indignation painting his face upon realizing there was a “missing” burger. “I ordered four burgers. Why are there only three?!” he bellowed across the table, attracting unwanted attention.
The waiter, a paragon of patience, politely assured him, “I made sure I put them all in the bag, sir.”
“Are you blind?! This is only three!” His voice, dripping with condescension, cut through the hum of restaurant chatter.
At this point, I was ready to say something to defend this poor woman who was just trying to do her job, but my husband knew his father would just turn his fake rage on me and make a bigger scene. So, knowing I couldn’t stand for anyone being mistreated, he grabbed my hand lightly to urge me not to say anything.
I trust Sam’s instincts, especially when it comes to his father, so I pulled back and settled into my chair, watching the drama unfold.
Seeing that Benjamin was one of those unreasonable consumers who believed they were always right, the waiter apologized. She said, “Sorry, Sir. I’ll get you another one,” even though it was clear from her reaction that she was quite certain she’d brought all four.
The innocent woman walked away to get a fifth burger for my greedy FIL, and we sat looking at him with disgust but chose to say nothing to avoid inflaming the situation further. The waiter’s solution seemed to satisfy Benjamin momentarily, his smirk spreading across his face like a dark cloud.
Little did he know, the universe was about to serve him a HUGE slice of humble pie!
Fast forward to our arrival home, and the smugness quickly faded into sheer panic. My FIL’s face turned white as a sheet when he realized his wallet was missing! The atmosphere thickened with tension as he frantically searched, his mind racing back to the restaurant.
My husband and I exchanged knowing glances, the air heavy with unspoken thoughts.
In a twist of fate, my FIL, driven by desperation, called the restaurant, only to have the same waiter answer! The calm in her voice as she confirmed finding his wallet was almost palpable! But there was a major twist to the news he hadn’t expected…
The waiter informed him that the restaurant had a peculiar policy, one my FIL had always ridiculed on the walls and menus of the establishment, stating that any lost items unclaimed within an hour would be donated to charity
The realization hit him like a freight train! He quickly dropped the call and filled us in, “I think they gave away all my money, we need to go back!” I am not going to lie, seeing him all distressed and panicky left me feeling like justice was served, but it was only the beginning!
We rushed back to the restaurant, only to be met with the ultimate irony. The waiter, now wearing a grin of victory, handed him an envelope from the charity organization, thanking him for his “generous donation,” before pouring him a “complimentary drink.”
Inside were receipts detailing how the money from his wallet provided meals for several homeless individuals that evening!
Silence enveloped him, a rare moment of humility overtaking the usual pomp and bluster. My husband took this moment to gently address his father’s behavior, igniting a heartfelt discussion about respect, gratitude, and the ripple effect of our actions.
“Dad, you know what you did to that waiter was wrong, and it’s probably why you forgot your wallet at the restaurant,” he told him when we got to the safety of the car. “You always have this idea that you can do anything you want and there won’t be consequences,” Sam continued.
With tears in his eyes, he added, “You know that’s part of the reason why Mom isn’t with us today.”
What my husband was referring to was how Benjamin ended up living with us because his wife, Sam’s mother, divorced him and took everything. My FIL repeatedly cheated on Diana, a sweet and loving woman who would’ve given the world to Benjamin.
When she finally got tired of his entitlement, she took him to the cleaners in court, sharing a folder and footage of years of private investigations she’d done on her husband to prove his guilt. She’d known throughout his marriage about his infidelity but only confronted him once or twice, where he pompously told her
However, he definitely “answered” to her when she filed for divorce and won everything before selling it all and relocating to another country. Only Sam and I had contact with her via texts and sometimes video calls.
It was a painful yet cathartic experience for all, especially for my FIL, who had never acknowledged facing the consequences of his entitlement in such a direct and immediate way. The incident at the restaurant and Sam’s heartfelt confrontation marked a turning point, not just for my FIL but for our family as a whole.
The lesson from karma was a clear and profound one that led the man who once embodied entitlement and arrogance to vow to change. He began a journey of volunteering and connection with those he had overlooked—the homeless people who’d benefited from his loss.
Our family dinners, once tense affairs, transformed into sessions of meaningful conversation and laughter. My FIL, previously the source of strife, became the catalyst for unity, embodying the transformative power of kindness and empathy.
So, there it is: A story of how a misplaced wallet and a “missing” burger taught us all the invaluable lesson that no act of kindness, no matter how small, goes unnoticed by the universe. Karma, in its most poetic form, reminded us that humility and compassion pave the path to true fulfillment. And for my FIL, it was a lesson learned not a moment too late.
While Linda’s story about how karma finally knocked some sense into her FIL shows how sometimes it takes time for people to get the message, here’s another story that will make you halt before doing something stupid that you’ll regret later.
