When changing lanes, the rule for using turn signals is to signal at least 100 feet before making the change. This practice is crucial as it alerts other drivers and pedestrians to your intended maneuver, allowing them to react appropriately. Signaling in advance not only enhances safety but also promotes smoother traffic flow by providing adequate warning to surrounding vehicles.

Using a turn signal well in advance is particularly important in scenarios where multiple lanes are involved, as it gives other drivers enough time to assess the situation and adjust their speed or position if necessary. This consideration helps prevent accidents and misunderstandings on the road.

While there may be other options that suggest less stringent signaling requirements, such as signaling only when other vehicles are present or not signaling at all, adhering to the guideline of signaling 100 feet ahead ensures that you are communicating your intentions clearly and consistently, regardless of the presence of other cars.
