What is the best way to inform other drivers of your intention to turn or change lanes?

Using your signal lights well in advance is the best way to inform other drivers of your intention to turn or change lanes. Signal lights are specifically designed to communicate your plans to other road users, providing them with a clear and standardized indication of your intended actions. By activating your turn signal well ahead of the maneuver, you give other drivers ample time to react appropriately, which enhances overall safety on the road.

This method is recognized universally among drivers, making it easy for others to interpret your intentions quickly. It also helps to establish predictable traffic patterns, allowing for smoother transitions between movements. Proper signaling is not just a courtesy; it is a legal requirement in most places, aimed at preventing accidents and fostering a cooperative driving environment.
