The Utah Department of Transportation has received your request and we will be looking into the issue. Thank you for taking the time to let us know.

Thank you for contacting UDOT. The flashing yellow arrow for the eastbound left turn is disabled during certain parts of the day when the order of the movements change. This is to avoid what is called a perceived yellow trap. When the flashing yellow arrow for the eastbound left goes solid yellow, the first thought would be to finish turning before it turns red, however the westbound through would still be green which would cause an accident for the car that thought they could finish turning. Overall, this was done as a safety concern. We apologize for any inconvenience this may cause you. If you have any questions, feel free to call us directly at 801-887-3702.
