Traffic circles already confuse many American drivers. Now, a fresh legislative push aims to eliminate the requirement to use turn signals within these intersections in Utah. The move follows a controversial ticket that sparked a debate over whether current laws actually help or hurt traffic flow. If successful, this change could set a precedent for how motorists navigate roundabouts across the nation.
A Controversial Ticket Sparks Legal Change
The conversation started with a simple traffic stop. A friend of Utah State Representative Ariel Defay received a citation for failing to use a turn signal while exiting a roundabout. This incident highlighted a disconnect between the written law and how people actually drive. Most drivers focus on yielding and finding a gap in traffic rather than flipping their blinker lever.
Rep. Defay introduced House Bill 128 to amend the state code so drivers are no longer legally required to signal when entering or exiting a roundabout.
She argues that the current statute is vague. Many drivers do not know it exists. The bill specifically targets smaller roundabouts where the distance between entry and exit is short. In these tight spaces, signaling can often send mixed messages to other drivers.
Drivers often feel that the mechanics of a roundabout make signaling physically difficult. You are turning the steering wheel sharply to the left to navigate the curve. Simultaneously, the law expects you to flip the signal lever up to indicate a right turn for the exit. This requires awkward hand movements while maintaining control of the vehicle.
Here is a breakdown of the proposed changes in H.B. 128:
- Entry: Drivers would not need to signal when approaching the roundabout.
- Navigation: No signal is required while circulating the central island.
- Exit: The strict requirement to signal right before leaving would be removed for standard roundabouts.

Why Signaling in Circles Confuses Drivers
Roundabouts are designed to keep traffic moving continuously. The primary rule is to yield to the left. However, adding turn signals to the mix creates a layer of complexity that some experts say is unnecessary.
When a car is in a small roundabout for only three seconds, a turn signal provides little value to other motorists.
If a driver signals too early, a car waiting to enter might pull out in front of them, causing a crash. If they signal too late, the car behind them has already reacted to their brake lights. The window for a useful signal is incredibly small. This reality makes the law feel like a “gotcha” tactic rather than a safety measure.
Most American drivers treat roundabouts simply as a bend in the road. They do not view it as a series of distinct turns. Because the natural flow guides the car through the exit, using a blinker feels counterintuitive.
Common driver frustrations include:
- Unsure if they should signal left to stay in or right to get out.
- The blinker often auto-cancels due to steering wheel movement.
- Worrying about signals takes attention away from watching for pedestrians.
- Fear of getting a ticket for a rule they did not know existed.
Navigating Different Rules Across State Lines
The confusion in Utah reflects a broader issue across the United States. There is no single federal standard for how to drive in a roundabout. Each state sets its own vehicle code. This creates a patchwork of regulations that can trap travelers.
A driver who is perfectly legal in one state could be breaking the law just across the border.
In Washington State, for example, the law explicitly requires drivers to signal their exit. Failure to do so can result in a fine. Conversely, the Indiana Supreme Court ruled in 2022 that drivers are not required to signal when exiting a roundabout. The court reasoned that the roundabout itself is one continuous intersection, not a series of turns.
This inconsistency makes it hard for national safety organizations to teach a single method. Driver education courses struggle to keep up with shifting local statutes.
| State | Signal Requirement | Context |
|---|---|---|
| California | Required | Must signal intent to exit (Right turn signal). |
| Indiana | Not Required | Supreme Court ruling says signaling is not mandated. |
| Utah | Pending | H.B. 128 seeks to remove the requirement. |
| Washington | Required | Must signal before leaving the circle. |
Balancing Traffic Flow With Public Safety
Opponents of the bill worry about pedestrian safety. They argue that turn signals are not just for other cars. They communicate intent to people walking across the crosswalks at the exit points.
If a pedestrian knows a car is exiting, they know to wait on the curb.
Without a signal, the pedestrian has to guess the driver’s path. This could lead to hesitation or dangerous situations where a walker steps out in front of an exiting vehicle. Safety advocates insist that communication between road users is vital, even if it feels inconvenient.
However, data shows that roundabouts are already much safer than traditional intersections. According to the Insurance Institute for Highway Safety (IIHS), roundabouts reduce fatal accidents by up to 90 percent. They also reduce injury crashes by 75 percent.
This safety record exists despite the confusion over signaling. This suggests that the geometry of the road does the heavy lifting for safety. The slow speeds and angled entry points prevent high-speed T-bone collisions. Whether a driver signals or not, the design forces them to slow down.
Law enforcement officers also have mixed feelings. Some appreciate the clear rules that signals provide. It gives them a concrete reason to stop unsafe drivers. Others agree with Rep. Defay that writing tickets for a technicality wastes police resources. They prefer to focus on aggressive driving or failure to yield, which are the actual causes of accidents in circles.
The outcome of H.B. 128 will likely influence other states grappling with this issue. If Utah successfully removes the mandate without a spike in accidents, other legislatures may follow suit. It represents a shift toward practical laws that match human behavior.
As roundabouts become more common in the US, the rules governing them must evolve. The goal is to keep traffic flowing smoothly without burdening drivers with confusing regulations.
Traffic laws work best when they align with common sense. Utah’s potential move to scrap turn signal requirements in roundabouts acknowledges that over-regulation can sometimes hinder the natural flow of the road. While safety remains the top priority, clarity is just as important. Drivers should not have to fear a ticket for driving in a way that feels natural and safe.
