Termination of this zone is indicated by
placing a Passing Permitted (RB-32) sign.
The sign informs drivers that passing is
permitted when safe to do so. It also
implies that vehicles should proceed with
caution and care when passing.
The Do Not Pass and Passing Permitted
signs are standard regulatory signs with
black symbols on a white background.
A red annular ring with interdictory stroke
indicates a prohibitive message. A green
annular ring indicates a positive, permissive
message.
