Summary

The 2009 edition of the federal MUTCD suggests the use of the flashing yellow arrow (FYA) indication in lieu of the green ball indication for permissive left-turn signals in the presence of separate signal heads. Currently, there are no clear guidelines on how to implement FYA with Protected-Permissive Left Turn (PPLT) operations in Texas. The objective of this research was to develop guidelines for the implementation of the FYA with PPLT operations that are suitable for statewide application in Texas.
