When must you signal while driving?

The requirement to signal while driving is fundamental for ensuring safety on the road and effective communication with other drivers. Signaling is most important when changing lanes or turning at an intersection because these maneuvers can significantly affect the flow of traffic and the actions of other drivers.

When you signal your intention to change lanes or turn, you provide crucial information to other drivers about your movements, allowing them to adjust their speed or position accordingly. This helps to prevent potential accidents and misunderstandings on the road. It is a key principle of defensive driving, promoting awareness and cooperation among all road users.

The need to signal only when pulling over, entering a parking lot, or driving below the speed limit does not encompass the full range of driving situations where communication with other drivers is essential. Proper signaling includes various driving scenarios beyond just those mentioned in the other options, reinforcing the importance of being aware of your surroundings and the actions of those around you while behind the wheel. Thus, always signaling when changing lanes or making turns aligns with the safest driving practices mandated by road regulations.
