Which is a common signaling method for lane changes?

Using turn signals to indicate the desired direction is a common and legally mandated signaling method for lane changes. Turn signals serve to communicate a driver's intentions to other road users, providing a clear indication of where the vehicle is planning to move next. This practice enhances road safety by allowing other drivers and pedestrians to anticipate the actions of the vehicle, reducing the likelihood of collisions that can occur when lane changes are made without signaling.

In many jurisdictions, failing to use turn signals while changing lanes can result in penalties, as it is considered a violation of traffic laws. The consistent use of turn signals is part of defensive driving techniques, promoting awareness and communication between drivers. This method of signaling is also standardized across various types of vehicles, making it universally understood among drivers on the road.
