A two-headed arrow with one head pointing straight ahead and the other pointing to the left means?

The presence of a two-headed arrow, with one head pointing straight ahead and the other pointing to the left, indicates that drivers have the option to either proceed straight or make a left turn. This traffic signal is used to inform drivers that they can choose their path based on their driving intentions, allowing for flexibility in navigation at that intersection.

This dual-arrow symbol effectively conveys that both options are legally permissible, thus helping to facilitate better traffic flow and communication among drivers. Understanding this signal is crucial for safe and lawful driving, as it allows drivers to make choices that suit their travel plans without ambiguity.
