What does a two-headed arrow with one head pointing straight and the other left indicate?

The symbol of a two-headed arrow, with one head pointing straight and the other pointing left, indicates that drivers have the option to either proceed straight ahead or turn left at that intersection. This sign is designed to offer flexibility to drivers, allowing them to choose their route without any restrictions on direction, provided that conditions permit.

This is particularly useful in intersections where both straight and left turns are common, facilitating a smoother flow of traffic. It's important for drivers to be aware of their surroundings and traffic signals while making their choice, but this sign clearly communicates that both maneuvers are allowable. This makes it essential for drivers to be attentive to other road users and yield to pedestrians or other vehicles as necessary when making their decision.

The other options do not accurately describe the meaning of the two-headed arrow. For example, stating that a mandatory left turn is required would misrepresent the flexibility that this symbol offers. Similarly, suggesting that only a straight path is allowed ignores the left turn option available to drivers.
