When must you use turn signals in Pennsylvania?

Using turn signals is a critical aspect of responsible driving, as it helps communicate your intentions to other road users, thereby enhancing safety. In Pennsylvania, the law requires drivers to signal their intent to turn at least 100 feet before making a turn. This distance gives other drivers and pedestrians adequate time to react to your impending maneuver and can help prevent accidents.

It's important to adhere to this rule as it establishes a clear and consistent expectation on the road. Signaling well in advance allows for smoother traffic flow and demonstrates courteous driving behavior. This practice is not just a suggestion, but a legal requirement, ensuring that all drivers are aware of their responsibilities to indicate their movements clearly and promptly.

Other options do not align with the established requirements: signaling only when changing lanes does not cover the full scope of when turn signals should be used, while signaling whenever a driver feels it is appropriate is too subjective and could lead to confusion on the road. Additionally, the idea that turn signals are not required is incorrect, as they are indeed mandated by law for safety and communication purposes.
