When should you use your turn signals?

Using turn signals before changing lanes or turning is a critical aspect of safe driving. Turn signals communicate your intentions to other drivers and pedestrians, helping to ensure that everyone on the road is aware of your actions. This communication is essential for preventing accidents, as it allows other road users to anticipate what you plan to do next.

Turn signals should be activated in advance of making a maneuver, ideally about 100 feet before you change lanes or turn. This gives other drivers enough time to react accordingly. Consistent use of turn signals not only adheres to traffic laws but also promotes safe driving practices.

The other options underestimate the importance of signaling. Relying solely on signaling when changing lanes ignores situations requiring signals when making turns, which is equally important for road safety. Using signals based on a personal decision undermines the consistent communication needed on busy roads. Lastly, only signaling when other cars are present does not account for the safety of pedestrians and bicyclists, who also need to be aware of a driver's intended actions.
