What is the correct procedure for using turn signals?

• A. Activate the turn signal immediately before turning
• B. Activate the turn signal at least 100 feet before turning or changing lanes
• C. Only use turn signals in heavy traffic
• D. Turn on the signal once in the intersection

Answer: (B)

Activating the turn signal at least 100 feet before turning or changing lanes is crucial for ensuring safety on the road. This practice provides adequate notice to drivers and pedestrians around you that you intend to make a maneuver, allowing them to adjust their actions accordingly. The three key reasons for this timing are communication, predictability, and safety.

Communication is critical in driving; turn signals serve as a way to inform others of your intended actions. Providing this information well in advance helps prevent misunderstandings that could lead to accidents.

Predictability in traffic behavior helps maintain an orderly flow. When drivers signal their intentions early, other road users can anticipate movements, which supports smoother traffic patterns.

Safety is enhanced because it gives adequate time for other drivers to react, reducing the likelihood of collisions, particularly in busy intersections or merging situations.

In contrast, activating the turn signal immediately before turning or only in heavy traffic does not allow sufficient time for others to notice your intentions. Similarly, signaling only once in the intersection leaves little time for nearby vehicles to adjust their speed or position in response to your movements. Following the correct procedure maximizes the effectiveness of turn signals and upholds road safety standards.
