LAMESA — The Texas Department of Transportation is set to install new traffic signals with flashing yellow left turn arrows at several locations in the city of Lamesa as part of an effort to upgrade the signals to meet Federal Highway Administration (FHWA) standards.

The traffic signals are scheduled to be installed over the next two weeks; work begins today. Signal intersection locations are:

  • US 87 and US 180
  • US 180 and Avenue G
  • US 180 and SH 137
  • US 87 and FM 2592
  • SH 137 and S. 1st Street

“The flashing-yellow, left-turn arrows were adopted in 2009 by the FHWA as the national standard for permissive left-turn signals,” said Jeremy Dearing, P.E., TxDOT transportation operations engineer. “The signals are now being used by TxDOT and local jurisdictions across the state.”

Motorists should be aware that oncoming traffic has a green light when the flashing yellow arrow is displayed.

“The flashing yellow-arrow, left-turn signals are gradually being phased in to replace the traditional circular green signals,” Dearing added. “The flashing yellow arrow is being used to indicate traffic is permitted to turn left but must still yield to oncoming traffic. This is different from the old green arrow signal which means traffic turning left is protected and has the right of way.” 

Flashing yellow arrows will continue to be retrofitted where appropriate at existing signals when traffic control equipment is upgraded or replaced.

Work will take place weather permitting.
