When signaling a lane change, which of the following is true?

Always signaling when changing lanes is crucial for maintaining safety on the road. This practice ensures that other drivers and pedestrians are aware of your intentions, which helps prevent accidents and promotes smoother traffic flow. Signaling is a fundamental part of defensive driving; it communicates your next move to those around you, so they can react accordingly. Regardless of whether other vehicles are present or the traffic situation, the act of signaling contributes to overall situational awareness and helps foster a culture of caution and respect among drivers.

Options that suggest signaling only when other vehicles are present, not at all if no one is around, or only in specific scenarios do not align with safe driving principles. Every lane change should be preceded by a signal, reinforcing the practice as a standard part of driving etiquette.
