Final answer:
Signaling continuously in the last 100 feet before a turn is generally a good habit for safety reasons, although exceptions include when turning is protected by a green arrow, in a designated turn lane, or when no other vehicles are present. Signaling helps reduce accidents and is a part of safe driving practices.
Step-by-step explanation:
It is a good habit to signal continuously during the last 100 feet before you turn at an intersection to notify other drivers and pedestrians of your intention to turn. While there are certain situations where signaling may not be strictly necessary, such as:
- when your turn is protected by a green arrow, implying a dedicated turn phase without opposing or cross-traffic,
- when there are no other vehicles around, though it is still a good practice to signal to maintain the habit, and in case any hidden vehicles or pedestrians are present,
- when you are in a designated turn lane where the direction is clear, but signaling still indicates your intention to turn for any observers who may have an obstructed view of the lane markings.
Despite exceptions, signaling is a critical aspect of safe driving practices and is typically required by law. The purpose of signaling is not only to comply with legal requirements but also to contribute to overall road safety by reducing confusion and the potential for accidents at intersections.
