This sign warns drivers to __________.

The correct answer identifies the need for drivers to slow down for a turn to the left, which is a common traffic scenario. Signs that indicate a left turn typically feature symbols or arrows that alert drivers to the approaching curve. When encountering such a warning, it is essential for drivers to reduce their speed to ensure they can navigate the turn safely without losing control or endangering themselves or other road users.

Familiarity with this type of sign is crucial for maintaining safe driving practices. Slowing down allows the driver to evaluate the intersection, check for oncoming traffic, and assess any other potential hazards, such as pedestrians or cyclists. This is particularly important in areas where road conditions may change or where visibility is reduced.

Understanding this context helps drivers appreciate the importance of adhering to such warnings, which ultimately contributes to road safety for everyone.
