Who Is at Fault in a Left-Turn Crash in Utah?

Short answer: In most left-turn crashes, the driver turning left is found mostly or entirely at fault, because Utah law requires a left-turning driver to yield to oncoming traffic that is close enough to be an immediate hazard. But “usually” is not “always.” If the straight-through driver was speeding, ran a red light or was not paying attention, fault can be shared, and that split changes what each side recovers.

Left-turn crashes tend to be serious because they are often side impacts or near head-on hits at intersection speed. They also tend to produce two very different stories. Here is how Utah law sorts them out.

The Basic Rule: The Left-Turning Driver Yields

Utah Code 41-6a-903 says a driver intending to turn left “shall yield the right-of-way to any vehicle approaching from the opposite direction which is so close to the turning vehicle as to constitute an immediate hazard” (Utah Code 41-6a-903(1)(a)).

That duty applies whether the turn is at a signal, a stop sign or a driveway. The turning driver has to judge the gap, and if an oncoming car was close enough that the turn put it in danger, the turn should have waited.

Utah’s signal statute says the same thing for a green light. A driver facing a circular green may go straight or turn, but must yield to other vehicles and pedestrians lawfully within the intersection or an adjacent crosswalk (Utah Code 41-6a-305(2)(a)). A green light lets a driver start a left turn. It does not give the turning driver the right-of-way over oncoming traffic.

Green Arrows, Flashing Yellow Arrows and Yellow Lights

Signal type often becomes the center of the dispute.

• Green arrow. A driver facing a green arrow may cautiously enter the intersection only to make the movement the arrow shows, and must still yield to pedestrians in an adjacent crosswalk and to other traffic lawfully using the intersection (41-6a-305(2)(b)). If oncoming traffic had a red at the same time, an oncoming driver who came through may be the one at fault.
• Flashing yellow arrow. Many Utah intersections use a flashing yellow arrow for left turns. Utah’s signal statute does not describe the flashing yellow arrow separately, so we will not tell you it has a special rule. What we can say is that the general left-turn rule in 41-6a-903 still applies to any left turn, and a flashing yellow signal allows a driver to proceed only cautiously (Utah Code 41-6a-307(1)(c)). A driver turning on a flashing yellow arrow is turning across traffic that may have a green.
• Steady yellow. Under Utah law, a steady yellow warns that the green movement is ending (41-6a-305(3)(a)). A turning driver waiting in the intersection often tries to finish the turn on yellow. Whether that was reasonable depends on whether oncoming traffic was stopping or coming through.

Because the light matters so much, the exact signal each driver faced at the moment of impact is usually the first thing to pin down.

When the Straight-Through Driver Shares the Blame

The oncoming driver has duties too, and insurers for the turning driver will look hard at them.

• Running a red light. A driver facing a steady red may not enter the intersection unless another signal allows the movement, and must stop at the stop line (41-6a-305(4)(a)). An oncoming driver who ran the red can end up with most of the fault.
• Speeding. Utah requires drivers to keep a speed that is reasonable and prudent under the conditions, including when approaching and crossing an intersection (Utah Code 41-6a-601(1)(a)). Speed matters in two ways: a car traveling well over the limit closes the gap faster than a turning driver would expect, and it has less time to stop.
• Not keeping a lookout. A distracted straight-through driver who could have braked or steered and did not may be assigned some share of fault.

The turning driver’s insurer will often argue one of these even with thin evidence. That is why speed evidence, like vehicle data, video and crush damage analysis, can decide a left-turn case.

How Utah Splits the Fault

Utah uses modified comparative fault. You can recover from a defendant only if the combined fault of the defendants and others assigned blame is greater than your own, and no defendant pays more than its own percentage of the damages (Utah Code 78B-5-818; 78B-5-820). In practice, a person found 50% or more at fault recovers nothing from the other side.

That rule makes the percentage fight in a left-turn crash high stakes. For the straight-through driver, a finding of some speeding might reduce the recovery. For the turning driver, arguing that the other car was going fast is often the only path to any recovery. More on the rule is in can I still recover if I was partly at fault in Utah.

Motorcycles and Left Turns

Riders see this crash more than anyone. The driver turning left often says they never saw the motorcycle. That is not a defense to the duty to yield, but it usually leads to an argument about the rider’s speed. Our guide to motorcycle accident claims in Utah covers the insurance issues riders face, including why many motorcycle policies do not carry PIP.

Evidence That Settles a Left-Turn Dispute

Since the two drivers usually disagree, neutral evidence matters most.

• Video from dash cameras, nearby businesses and buses or other commercial vehicles.
• Witnesses, especially drivers who were stopped at the light and saw which signal was showing.
• Vehicle event data showing speed and braking in the seconds before impact.
• Damage location. Where each car was hit can show where the turning car was in the turn.
• The police report and any citation, which you can request using our guide to getting a Utah police crash report.

Video and vehicle data are the pieces most likely to disappear. Ask about cameras quickly, and do not let a car be repaired or scrapped before it has been photographed if fault is disputed.

If You Were Hit by a Left-Turning Driver

Start with your own PIP coverage for medical bills, since Utah requires it on most car policies. See is Utah a no-fault state. Get treatment, keep records, and be cautious with the other insurer until you know what they are arguing about fault. Most Utah injury claims have a four-year filing deadline (Utah Code 78B-2-307(4)), but a claim involving a government vehicle requires a written notice of claim within one year (Utah Code 63G-7-402).
