Kingsport installs new signals to improve left-turn safety

Posted: Updated:


Drivers in Kingsport may notice a change along some roads: flashing yellow turn signals.

The signals are posted over left-turn lanes at intersections along Fort Henry Drive in the Colonial Heights area from Interstate 81 to the intersection with Moreland Drive.

"Flashing yellow turn signals have shown to be a more efficient way to allow left turn movements at busy intersections by lengthening the period where turn movements are authorized," said Kingsport Traffic Engineer Tim Elsea.  "The Federal Highway Administration has demonstrated that these signals allow additional traffic flexibility while preserving safety." 

The signals have four lights:
  • a red arrow meaning no turning allowed
  • a steady-yellow arrow meaning unrestricted turning movements are allowed as gaps in oncoming traffic allow, but that opportunity is about to end
  • a flashing yellow arrow allowing turning movements when oncoming lanes are clear. 
  • a steady-green arrow meaning left turns are unrestricted
"When the flashing-yellow arrow is displayed, motorists are allowed to turn left when there are gaps in oncoming traffic or no pedestrians in the intersection," Elsea said.   "Motorists may also turn left normally when a green arrow is displayed and oncoming traffic has stopped. They should not turn left when the red left-turn arrow is displayed."

The city posted information on how the traffic signals work :
