When should a driver signal before making a turn?

The correct choice emphasizes the importance of signaling well in advance of making a turn to ensure that other drivers and pedestrians are aware of your intentions. Signaling at least 75 to 100 feet before making a turn strikes a balance between providing adequate warning to other road users and allowing the driver to prepare for the maneuver safely. This distance gives sufficient time for surrounding traffic, especially in urban areas or on busy roads, to adjust their speed or position accordingly, thereby enhancing road safety.

Signaling at this distance is part of the standard driving practices taught in driver education to promote predictability and communication on the road, which are crucial for preventing accidents. By giving clear signals well in advance, drivers contribute positively to the overall flow of traffic and reduce the chances of confusion among other road users.
