Caution: New flashing yellow traffic signals installed on U.S. 49


The Mississippi Department of Transportation is nearing completion of traffic signal upgrades in Forrest County.

The $5.2 million project included installing new flashing yellow arrow traffic signals to intersections along U.S. 49 in Hattiesburg.

The new signals are more efficient for motorists turning left and have demonstrated a reduction in crashes.

“The flashing yellow arrow left-turn signal is safer than the traditional circular green left-turn signal, because some drivers perceive any green signal to mean go,” said Tom King, Southern Transportation District Commissioner. “The new flashing yellow arrow left-turn signal provides a more direct message to drivers, telling them to yield to oncoming traffic and pedestrians when it is flashing.”

Flashing yellow left-turn signals give MDOT engineers the flexibility to use specific signals during different times of the day. This will reduce wait times at intersections using the new signals.

To help motorists navigate the new signals, safety information and a video are available at /flashing-yellow-arrow/.

The improvement project along U.S. Highway 49 is being performed by Webster Electric and is expected to be completed May 31.
