How should you indicate a lane change?

Indicating a lane change is primarily done for safety and communication with other drivers. Using your turn signal before making the change is the correct approach because it alerts other drivers of your intentions, allowing them to react appropriately. This practice helps to minimize the risk of accidents by creating a clearer picture of your movements on the road.

Using your horn, waving your hand, or speeding up do not serve the same purpose. Honking could startle other drivers rather than inform them, hand gestures can be misinterpreted, and speeding can increase danger by reducing your ability to make safe decisions. Relying on the turn signal is the standard and safest method to convey your intention to change lanes.
