Turn on your________ well in advance of your maneuver to turn or change lanes.

The correct answer is the turn signal. Using your turn signal well in advance of a turn or lane change is essential for safe driving. It communicates your intentions to other road users, such as drivers, cyclists, and pedestrians, allowing them to anticipate your movements and adjust their own as necessary. This simple gesture helps to reduce the risk of collisions and enhances overall traffic safety.

Using the turn signal for an adequate duration before making your maneuver is key; it provides a clear indication that you are about to change direction. This practice aligns with traffic laws in many areas, which require drivers to signal their intentions to ensure the safety of everyone on the road. By signaling early, you give others time to react appropriately, making the roads safer for all.
