What is the best practice if you want to ensure your turn signal is visible?

Using hand signals is the best practice to ensure your turn signal is visible because they provide a clear and noticeable indication of your intended direction, especially when other vehicle signals may not be easily seen or are malfunctioning. Hand signals can be particularly effective during daylight or in situations where your vehicle lights are obscured. They communicate to other drivers and pedestrians that you are about to make a turn or change lanes, thus enhancing safety on the road.

Hazard lights are typically used to indicate a vehicle is stationary or moving slowly due to an emergency, and while they are visible, they do not convey specific turning intentions. Staying in a center lane does not necessarily enhance the visibility of your turn signals, as lane positioning is more related to the flow of traffic rather than signaling intent. Driving at a slower speed may help in certain circumstances but does not guarantee that your turn signal will be clearly noticed by others. Therefore, hand signals serve as a direct and effective method to ensure your intentions are communicated clearly to other road users.
