This sign means:

Four-lane traffic ahead.
Divided highway ahead.
Two-way traffic ahead.
The Correct Answer and Explanation is :
The correct answer is: Two-way traffic ahead.
Explanation:
This sign indicates that the road you are on is transitioning into a section where traffic will be moving in both directions. Specifically, the two-way traffic symbol typically means that the lane you are traveling in could be joined by vehicles traveling in the opposite direction, and drivers must be extra cautious.
The symbol on the sign consists of two parallel lines with arrows pointing in opposite directions. This design is meant to warn drivers that they are leaving a one-way section of the road or highway and entering a two-way road, where vehicles can travel in both directions.
This sign is essential for several reasons:
- Alerting Drivers: It helps drivers be aware of the change in traffic flow. Without this sign, drivers might unknowingly expect one-way traffic and may fail to anticipate vehicles coming from the opposite direction.
- Safety Precaution: In areas where roads split, such as when transitioning from highways or divided lanes into a more open area, two-way traffic can cause confusion. This sign gives drivers the chance to adjust their speed, positioning, and awareness before encountering vehicles traveling in the opposite direction.
- Road Design: A divided highway is different from a two-way road. A divided highway has physical barriers or medians to separate the traffic moving in opposite directions, while a two-way road may not have such physical separation. This is another reason why it’s vital to pay attention to these types of signs.
- Legal Requirements: In many places, it’s required by law to pay attention to these traffic signs to prevent accidents caused by drivers failing to adjust to new road conditions. Ignoring the sign could lead to dangerous collisions or wrong-way driving, which can result in severe accidents.
In summary, the two-way traffic sign is an important warning for drivers to be aware of oncoming vehicles, helping them navigate safely through areas where traffic is flowing in opposite directions.
