Lawmaker Just Exposed One Utah Law That’s Been Catching Drivers Offguard For Years
Americans break thousands of obscure traffic laws every single day without even knowing it.
One Utah lawmaker just found out the hard way that her state has been enforcing a rule nobody seemed to know existed.
And what she discovered about roundabout signals is going to make every driver in Utah question what other laws are lurking in the books.
The Traffic Stop That Started Everything
Rep. Ariel Defay thought her friend was joking when she got pulled over for not signaling in a roundabout.
"She came to me and said, 'Is this really a law? I don't even know if it's true,'" Defay told KSL News.
Turns out it wasn't a joke at all.
Utah Code Section 41-6a-804 requires drivers to signal before turning, changing lanes, or moving left or right on any roadway.
That includes roundabouts.
Every single one.
Defay dug into Utah's traffic code and found that drivers are supposed to signal both entering and exiting every roundabout, regardless of which exit they're taking.
The Kaysville Republican couldn't believe what she was reading.
Most people in her district had no idea this law even existed.
Utah Legislature Takes Action
Defay introduced House Bill 128 last week to kill the requirement.
The bill sailed through its first hearing before the House Transportation Committee on Friday.
The problem isn't just that nobody knows about the rule.
The bigger issue is that the law makes no practical sense for how roundabouts actually work.
"There are many exits while you're going in a circle," Defay explained.
"By the time you have signaled, you may be beyond one exit to another exit."
"It's very confusing which exit you're intending to leave from."
Think about it.
You're supposed to signal continuously for 100 feet before any turn under Utah law.
But if the distance between exits in a roundabout is less than 100 feet, you'd be signaling past the first exit while trying to reach the second or third exit.
That doesn't help other drivers figure out your intentions.
It just confuses everyone on the road.
The Rule Nobody Follows
Here's what makes this law particularly ridiculous.
Roundabouts only have one direction of travel when you enter.
There's nowhere else to go except into the circle.
So what exactly are you signaling when you enter?
That you're doing the only thing you're allowed to do?
Exiting creates the same problem.
Drivers are already watching for traffic, yielding to vehicles in the circle, and tracking which of several exits they need to take.
Adding a turn signal to that list just creates one more thing to worry about while navigating an already confusing intersection.
The law's obscurity suggests it hasn't been a cornerstone of traffic enforcement anyway.
Most cops probably don't even know it exists.
But the fact that it's on the books means any officer who wants to pull someone over has an easy excuse to do it.
Everyone going through a roundabout is technically breaking the law.
Roundabout Confusion Hits Every State
Utah isn't alone in having unclear roundabout laws.
A Washington state traffic expert surveyed 16 local law enforcement officers about whether drivers must signal when exiting roundabouts.
He got three different answers from different police departments.
Nobody could agree on what the law actually required.
That's because most states wrote their turn signal laws back in the 1970s, long before roundabouts became common in America.
Minnesota explicitly exempts drivers from signaling once they're inside a roundabout, though they still have to signal when entering.
Other states have vague language that could technically require signals but nobody enforces it.
The confusion creates a perfect storm where cops can pull over any driver they want under the guise of a traffic violation that most people don't even know exists.
What Happens If The Bill Passes
Defay's bill doesn't eliminate all signaling requirements in roundabouts.
Drivers in two-lane roundabouts would still need to signal while inside them to show which lane they're using.
That makes sense because other drivers actually need that information to navigate safely.
But for single-lane roundabouts, the signal requirement would disappear entirely.
No more pretending to signal an intention that's already obvious from your position on the road.
"I don't know how law enforcement will feel about it, but I think from the general population it will be a very enthusiastic 'Yes,' for this legislation," Defay said.
The real question is what other obscure traffic laws are sitting in state codes just waiting to trap unsuspecting drivers.
Traffic laws written 50 years ago don't account for modern road designs like roundabouts.
As infrastructure changes, the laws need to change with it.
Otherwise states end up with rules on the books that everyone breaks without knowing it.
And that's not safety enforcement.
That's a trap.
