Are Roundabouts More Dangerous Than Normal Intersections?

Many American drivers approach roundabouts with some trepidation. That’s because these types of intersections are uncommon in the States.

As proof of that, recent estimates put the number of roundabouts at 10,000. In contrast, there are about 320,000 traffic signals and millions of other four-way intersections. 

This lack of familiarity raises questions about whether roundabouts are more dangerous than regular four-way stop. Here’s what the data shows and how you can stay safe in a roundabout.

What Is a Roundabout?

A roundabout is a circular intersection. Approaching vehicles yield to the traffic inside and enter once it is safe. Traffic travels around the circle in a single direction and allows motorists to exit at any connecting street, even the one from which they arrived. 

Roundabouts may have a single lane or multiple lanes to accommodate travelers. Other names for this type of junction are “rotary” and “traffic circle.“

Why Does the United States Use Traffic Lights Instead of Roundabouts?

Roundabouts are much more commonplace in Europe. Early versions did not stick to the format that roads generally use today and lacked safety and efficiency. 

In the 1960s, traffic engineers realized that the way to improve traffic flow and safety was by having incoming vehicles yield. However, the U.S. started expanding its roads and highway system in the 1950s and opted for traffic lights instead of the less efficient traffic circles of the time.

Over the years, some municipalities have wanted to use roundabouts. In some cases, the locals have resisted their adoption out of fear that these rotaries would be unsafe or inconvenient. 

Are Roundabouts More Dangerous or Safer Than Normal Intersections?

An overwhelming amount of data shows that roundabouts are safer and more efficient than normal intersections with traffic lights. The Federal Highway Administration discovered that roundabouts lead to a 90% decrease in fatalities and 75% fewer injuries. 

Still, there are cases where new roundabouts have led to an increase in crashes, particularly due to drivers’ unfamiliarity when converting a traffic signal intersection to a roundabout. Notably, single-vehicle crashes may go up, usually affecting impaired drivers. Keep in mind that, though the number of total crashes goes up, the number of injury-causing and fatal collisions decreases.

Why Are Roundabouts Usually Safer Than the Typical Intersection?

Roundabouts decrease the likelihood and severity of collisions because they encourage slower travel speeds at a junction of roads. In contrast, drivers are typically moving at the speed limit or even faster through green traffic lights. When accidents happen, the outcome can be devastating.

Also, many drivers speed up to beat a changing traffic light. This leads to speeding, running red lights or stopping abruptly, which are all recipes for serious accidents. 

Likewise, the one-way flow of the roundabout greatly reduces the risk of head-on collisions and T-bone accidents. These are some of the deadliest types of crashes but become much less likely with roundabouts. 

Plus, traffic lights rely on power and electrical wiring that can malfunction. Though drivers generally need to treat light outages as a four-way stop, confusion easily arises and creates accidents or congestion. These issues are not a concern with a roundabout as traffic can keep flowing smoothly. 

Are There Any Other Benefits of Roundabouts?

Besides the safety benefits, roundabouts can easily accommodate intersections where more than two streets meet. This can make community planning easier. 

The smoother flow of traffic also leads to fewer delays and can encourage drivers to feel less stressed or hurried, which improves quality of life. In addition to preventing the safety issues that come with power outages, local governments save money on powering, maintaining or repairing traffic lights. They also don’t have to send officers to manage traffic when lights malfunction. 

Furthermore, a location can enjoy environmental benefits with reduced pollution and fuel consumption from lower congestion. The circle also provides an ideal spot for greenery. Without a need for turn lanes, intersections can take up less space. Some communities have even found that business sales increase with the adoption of roundabouts.

What Safety Challenges Can Arise With Roundabouts?

Granted, traffic circles are not without their issues. In particular, new roundabouts can cause uncertainty and a slight increase in accidents when communities implement them for the first time. 

Still, local officials shouldn’t underestimate the importance of educating residents about how to use roundabouts and providing helpful signage. Multilane rotaries experience the greatest number of accidents, so community education is especially important for motorists when installing these intersections.

As with any road, some drivers may still speed in the roundabout, and impaired travelers always create a hazard. Poor design can lead to unnecessary congestion, especially if plans do not account for cyclists and pedestrians. 

Even worse, some motorists might try to “cut” the roundabout by turning left against traffic to quickly get to a street. This opens the possibility of the highly dangerous kinds of T-bone and head-on crashes that roundabouts should avoid. Fortunately, these incidents are uncommon. 

How Can You Navigate Roundabouts Safely? 

You can securely use a roundabout by following a few safe driving tips. Start by approaching the intersection slowly and looking both ways before you enter. Remember, you have to yield to traffic traveling inside the roundabout. Also, look out for pedestrians and cyclists who may be crossing in front of you. 

In multilane roundabouts, promptly decide where you need to exit. Try not to switch lanes unnecessarily, as lane changes in roundabouts can lead to accidents. Be aware that the rightmost lane may force you to exit. Use your turn signal to show others where you are exiting the roundabout and keep an eye out for cyclists and pedestrians in the crosswalk.

It’s good practice not to ride next to large vehicles in multilane roundabouts. In most areas, these vehicles have the right to use multiple lanes, especially as they enter and exit.
