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.

- 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!
I Overheard My MIL Lying to Her Friends about Me Doing No Chores at Home & Decided to Outplay Her
I Overheard My MIL Lying to Her Friends about Me Doing No Chores at Home & Decided to Outplay Her
When Allison invited her mother-in-law’s friends over for an early brunch, little did they know they were about to uncover the truth behind months of false tales and witness a family dynamic transform right before their eyes.
Six weeks ago, my life changed forever—I became a mom to a beautiful baby boy. It’s been the most incredible yet toughest journey. My husband, Sammy, had to leave for a work project right after our son was born.

So, we planned for his mom to move in with us to help during the first few months. She promised to handle everything so I could recover from the delivery and focus on our newborn.
Life at home is not how I imagined, though. From the moment she arrived, my mother-in-law (MIL) seemed more interested in resting than helping. She quickly claimed her spot on the sofa, diving into her favorite TV series.

She also often mentions how her back pain keeps her from doing too much. I appreciate that she might be in discomfort, but it leaves me to manage everything—meals, cleaning, and, most of all, taking care of our son.
Each day feels like a marathon. I’m up with the baby several times at night, and by the time the sun rises, I’m already exhausted but need to start my day. Breakfast needs to be made, then the endless cycle of laundry, cleaning up, and of course, ensuring our little one is fed, changed, and happy.

Babies sure know how to double your laundry load! By mid-morning, I’ve usually forgotten about rest, my hair is a mess, and I’ve probably reheated my morning coffee three times already.
During these mornings and afternoons, my MIL continues her marathon too—of TV episodes. Occasionally, she’ll mention how much she wishes she could help more but is just too sore to move. Yet, as evening approaches, something remarkable happens. Her pain seems to miraculously fade, especially when her friends come over.

They don’t come every night, but when they do, it’s like a switch flips. Suddenly, she’s lively, chatting, and laughing, playing the perfect hostess in our kitchen, which she rarely uses for anything other than making coffee during the day.
Her transformation during these gatherings is stark. It’s confusing and, honestly, a bit hurtful. I find myself wondering how she can so easily entertain guests but not assist with simple tasks that would give me a moment to breathe or, dare I say, take a nap.

This contrast in her behavior has left me feeling both frustrated and skeptical of her claims of pain. I’m left to juggle the joys and trials of new motherhood essentially on my own.
This isn’t what I expected when we agreed that she would come to help. It’s a daily struggle, but I keep reminding myself that this phase won’t last forever. Still, a little genuine help would make a world of difference.

Last night, something happened that turned my usual frustration into outright anger. I was finishing up some late-night cleaning when I heard laughter and chatter from the kitchen.
My MIL was there, hosting her friends as she often does when she transforms in the evenings. Curious, I paused to listen, not intending to eavesdrop, but what I heard left me stunned and hurt.
My MIL was speaking loudly, and clearly, telling her friends that she’s been the one taking care of everything at home. She claimed she was cooking, cleaning, and mostly caring for my baby. Then, she added something that really got to me.

She said, “I don’t know what Sammy saw in her; she’s just lazing around all day, a real couch potato.” Her words were like a slap in the face. There I was, barely keeping my eyes open from exhaustion, and she was painting a picture of me as lazy and uninvolved.
The sense of betrayal was overwhelming. I felt anger boiling inside me. How could she lie so blatantly? How could she discredit all my efforts? It wasn’t just the physical exhaustion of caring for a newborn and a household that hurt. It was the emotional pain of being so unfairly judged in my own home.

I knew I couldn’t just confront her; that would only lead to more tension. So, I came up with a plan. A way to show her friends the truth without causing a scene. I decided I would invite them over myself, but earlier than they usually come. This way, they could see the real situation. They would see who was really on the couch and who was handling the chores and the baby.
So, today, I sent out a few messages, arranging for her friends to come over for what I called a special brunch. I planned it during a time when I usually have my hands full with baby duties and household chores.
Coincidentally, this was the time when my MIL usually settles in for her morning of TV. It was a simple plan, but I hoped it would reveal the truth. Maybe, just maybe, I could make her realize how her words and actions affect others around her.

This morning was a turning point in my home. I had planned a special brunch, inviting my mother-in-law’s friends to arrive much earlier than their usual evening visits. I was nervous but hopeful that today would bring some much-needed change.
As her friends arrived, they found my MIL asleep on the sofa with the TV blaring some morning show. There I was, in the next room, soothing my little boy who wasn’t feeling well. His little cries filled the air, quite the contrast to the usual laughter that echoes from the kitchen during her evening get-togethers.

The surprise on her friends’ faces was evident as they walked in. They weren’t used to seeing this scene. My MIL woke up, clearly disoriented and embarrassed, scrambling to turn off the TV and smooth out her hair. She tried to laugh it off, mumbling about not expecting anyone so early.
I took this opportunity to ask for her help with some simple tasks. First, I asked her to change the baby’s diaper. I told her the new diapers were in their usual place.

She hesitated, fumbled through the drawers, and couldn’t find them. I had to step in to show her where they were, something so routine for me, yet unfamiliar to her.
Then, as I started preparing food for everyone, I asked her to fetch the big salad bowl from the cabinet. Again, she looked lost in her own kitchen, opening the wrong cabinets before I guided her to the right one. Her friends watched, slowly piecing together the reality of the situation.

The atmosphere shifted noticeably. There were no more chuckles or light banter. Instead, an uncomfortable silence filled the room as her friends saw the truth behind the daily life in our home. My MIL’s face reddened with embarrassment as she realized how her stories had unraveled.
The morning progressed, and her friends began to help with the brunch, seeing firsthand how much I managed on my own. As they left, their parting looks were filled with a mix of sympathy and a new understanding.

After everyone had gone, there was a quiet moment between my MIL and me. It was awkward at first, but then she began to apologize. She admitted that she had been unfair and promised to start helping more genuinely. I could see she was sincere, maybe embarrassed by her own actions being brought to light.
From that day forward, things began to change. My MIL started taking on more responsibilities around the house and with her grandson. She wasn’t perfect overnight, but the effort was real. We started to find a new rhythm together, cooperating and sharing the duties that come with maintaining a home and caring for a child.

This experience taught us both valuable lessons in honesty and respect. It wasn’t just about exposing the lies; it was about rebuilding trust and understanding the real meaning of family support. Now, I can genuinely say our home feels more balanced and peaceful. It’s amazing how much can change when the truth comes to light.
