This sign means:

Answers
You can travel in either direction in this lane.
There is two-way traffic.
You are approaching a divided highway.
The Correct Answer and Explanation is:
The correct answer is: There is two-way traffic.
Explanation:
The sign depicted in the image is a two-way traffic warning sign, which alerts drivers that they are entering a roadway where traffic flows in both directions. The sign typically consists of a yellow diamond-shaped background with two black arrows: one pointing upward and the other downward. This design emphasizes the direction of the opposing traffic.
Purpose of the Sign:
This sign is crucial for safety as it helps drivers anticipate oncoming traffic. It is often placed:
- At the transition from a divided highway or one-way street to a two-way road.
- In areas where road conditions might change, such as construction zones.
Importance in Driving:
Understanding and adhering to this sign is essential for maintaining safe driving practices. On two-way roads:
- Stay in Your Lane: Drivers must remain in their designated lane and avoid crossing into oncoming traffic lanes, unless safely passing where permitted.
- Be Vigilant: Pay close attention to vehicles approaching from the opposite direction, especially on narrow or winding roads.
- Adhere to Speed Limits: Reducing speed when transitioning to a two-way road is prudent, as the risk of head-on collisions increases.
How It Differs from Other Signs:
- “You can travel in either direction in this lane” typically refers to center lanes marked for reversible traffic or turning lanes, which this sign does not represent.
- “You are approaching a divided highway” would be indicated by a different sign, often showing a divider symbol.
By recognizing and responding appropriately to the two-way traffic sign, drivers contribute to safer roadways for everyone.
