Abstract:

The use of the flashing yellow arrow (FYA) for permissive left turns is relatively new to California, with at least five

installations approved under a 2006 Federal Highway Administration (FHWA) Interim Approval memorandum.

Inclusion of formal guidance for the optional use of FYA in the 2009 edition of the Manual on Uniform Traffic

Control Devices for Streets and Highways (MUTCD) is expected to lead to heightened interest in applying the FYA

within California, and Caltrans would like to know more about the safety implications of the use of the FYA for

permissive left-turn lanes, particularly at intersections with railroad-preempted traffic signals.
