How should you signal when changing lanes?

When changing lanes, the correct approach is to use your turn signal to indicate your intention. This is essential for ensuring safety on the road. By signaling with your turn signal, you communicate your planned maneuver to other drivers, allowing them to anticipate your actions and adjust their driving if necessary. This practice helps prevent accidents and promotes smoother traffic flow.

Using hazard lights is not appropriate for signaling a lane change, as they are intended to indicate a vehicle that is stopped or in a situation requiring caution. Making eye contact with other drivers may be helpful at times, but it is not a reliable method for communicating lane changes, as this could lead to misunderstandings. Finally, failing to signal or making a swift change can create hazardous conditions, leading to collisions and confusion among other road users. Thus, using a turn signal is the safest and most effective way to communicate lane changes.
