What type of signal should you use when changing lanes?

Using turn signal indicators when changing lanes is essential for safe driving. Turn signals communicate your intention to other drivers and pedestrians, allowing them to anticipate your movement on the roadway. This is crucial for maintaining safety and preventing accidents, as it creates a clear understanding of your actions on the road.

Hand signals, while an alternative, are less commonly used in modern driving and can be difficult for other drivers to notice. Audible signals like honking are inappropriate for indicating lane changes, as honking typically serves as a warning or alert rather than a signal of intent to maneuver. Adjusting vehicle speed alone does not provide any indication to other road users about your intention to change lanes. Therefore, using turn signal indicators is the most effective and recognized method to signal a lane change, making it the best choice for this scenario.
