How far ahead must you signal a turn on open highways?

When driving on open highways, the requirement is to signal at least 300 feet ahead of your intended turn. This distance is designed to ensure that other drivers have ample time to notice your intention to change directions, thus enhancing safety. On highways, where vehicles typically travel at higher speeds, signaling well in advance is vital for preventing accidents and allowing other motorists to adjust their speed or position accordingly.

This practice not only adheres to traffic laws but also contributes to better traffic flow by informing surrounding vehicles of your planned maneuver. Adhering to this requirement is especially important since the fast-paced nature of highway driving means that shorter signaling distances may not give other drivers enough time to react appropriately.
