Warning Signs
Background color: yellow
Location: at the beginning of sharp turns or curves
The Turn/Advisory Speed sign warns drivers of an upcoming turn and provides a recommended speed for safely navigating it.
When you see this sign, slow down to the advised speed to safely complete the turn. The sign usually marks the beginning of the turn and ensures safe driving behavior in sharp curves.
Warning Signs
Background color: yellow
Location: transition sections between multi-lane and two-way roads, or construction zones
The Two-Way Traffic sign warns drivers of a transition from a divided or one-way section to a two-lane, two-way section of roadway. It reminds road users to expect oncoming traffic and is placed at critical points such as construction zones, lane merges, or changes from multi-lane freeways to two-lane highways.
This sign means traffic flows in both directions. If you were driving on a divided highway and see this sign, it signals that you are entering a two-lane, two-way section. Always stay in your lane and be prepared for oncoming traffic.
Warning Signs
Background color: yellow
Location: in advance of winding road sections with multiple curves
The Winding Road sign warns drivers of a section of road with three or more consecutive curves. It is used when multiple curve signs would be ineffective. This sign alerts motorists to reduce speed and drive carefully through the winding section. If the winding section exceeds one mile in length, an additional NEXT MILES plaque may be used.
This sign suggests multiple curves ahead. Slow down and stay alert for turns to avoid sudden maneuvers.
Warning Signs
Background color: yellow
Location: before yield-controlled intersections and crossings
The Yield Ahead sign warns road users of an upcoming YIELD sign. It is used where the YIELD sign might not be visible from a sufficient distance, ensuring drivers can react appropriately. It is also placed before intersections, entrances to expressways, and at crossings where drivers expect an acceleration lane but none exists.
The red inverted triangle on the sign reminds drivers to slow down and be prepared to yield the right-of-way. Always check for cross traffic and proceed only when it's safe.
