Left Turn Traffic Signal Receives Makeover

Red left arrow to replace solid red indicator

COLUMBUS (Wednesday, May 2, 2012) – The Ohio Department of Transportation (ODOT) is in the process of  switching 643 protected-only left turn signals at nearly 400 intersections throughout the state due to changes in federal regulations.

Currently, as motorists approach a designated left turn lane, the signal transitions from a green arrow to a yellow arrow, and then to a solid red circle.  The new signal will transition from a green arrow to a yellow arrow and then to a red arrow (as pictured below).  Drivers CANNOT turn on red arrows.

Installation of the new red arrows will take place statewide as older versions are scheduled for routine replacement at a cost of about $26 per signal.

The change is part of the 2009 Federal Highway Manual Uniform of Traffic Control Devices which requires “protected-only” left turn signals to have red arrows replace all circular red indicators.  The purpose of the change is to enhance uniformity and eliminate “left turn signal” signs. 

ODOT began installing the red arrows on April 12 as part of its annual systematic signal improvement program.
