Difference between Rotary and Roundabout

A rotary is a large, roundabout interchange in which drivers travel around a central island. Rotaries are unique to New England and are not found in other parts of the country. Roundabouts, on the other hand, are found throughout the US and Europe. roundabouts are typically smaller and have fewer lanes than rotaries. They are designed to slow down traffic and improve safety. So, what’s the difference between a rotary and a roundabout? Let’s take a closer look.

What is Rotary?

Rotary in traffic is a type of intersection where vehicles travel around a central island. Rotaries are often used in high-traffic areas as they allow for a continuous flow of traffic. One benefit of rotaries is that they can help to reduce traffic congestion and improve traffic flow. Additionally, rotaries often have less serious accidents than other types of intersections. This is because there is less chance for head-on collisions as vehicles are always entering and exiting the rotary in the same direction. Rotaries can be used in both urban and rural areas, and they are particularly common in Europe. While Rotary intersections can have many benefits, they can also be confusing for drivers who are not familiar with them. For this reason, it is important to yield to oncoming traffic and use caution when driving through a Rotary.

What is Roundabout?

A roundabout is a traffic circle designed to move traffic efficiently and safely through an intersection. Roundabouts are particularly effective at reducing the number of serious injuries and fatalities caused by high-speed right-angle collisions. They also minimize delays, reduce pollution, and conserve fuel. Roundabouts are typically built in areas with moderate to heavy traffic, and they can accommodate all types of vehicles, including bicycles and trucks. While roundabouts may seem confusing at first, they are actually quite simple to navigate. Drivers simply yield to traffic already in the circle and then enter the circle when there is an opening. Roundabouts typically have signs and markings to help drivers navigate the intersection safely.

Difference between Rotary and Roundabout

Rotary and roundabout are two words that are often used interchangeably, but there is actually a subtle difference between them. A Rotary is a type of intersection where traffic flows around a central island in a clockwise direction. A Roundabout, on the other hand, is a type of intersection where traffic flows around a central island in a counterclockwise direction. Both types of intersections can help to improve traffic flow and reduce congestion. However, Rotaries are typically larger than roundabouts and can accommodate more traffic. Additionally, Rotaries typically have yield signs at each approach, while roundabouts have stop signs or yield signs at each approach. When deciding which type of intersection to use, it is important to consider the amount of traffic that will be using the intersection and the available space.


Rotaries and roundabouts are two similar, yet different types of intersections. Both allow drivers to enter and exit the intersection without stopping, but there are some key differences. Roundabouts are typically smaller and have a single lane for entering and exiting. Rotaries have multiple lanes for entering and exiting, which can make them more confusing for drivers.
