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

The symbol of a two-headed arrow with one head pointing straight ahead and the other pointing left is used to indicate that drivers have the option to either proceed straight or turn left. This flexibility allows drivers to choose the direction that best fits their intended route while navigating an intersection or road configuration that accommodates both movements.

In contrast, other options imply mandatory actions, such as requiring a specific direction (turn left or proceed straight) or yielding to traffic, which is not indicated by this particular symbol. The presence of both directional arrows signifies the available choices for drivers rather than enforcing a single course of action, thereby making it clear that either path is permissible in this scenario.
