What is the primary reason for using turn signals?

The primary reason for using turn signals is to notify other drivers of your intentions. By signaling your intentions, you are providing critical information to those around you about what you plan to do, whether that involves making a turn, changing lanes, or merging into traffic. This communication helps to ensure safety on the roads by reducing confusion and the likelihood of accidents, as other drivers can anticipate your movements and react accordingly.

The other options do not capture the fundamental safety purpose of turn signals. Checking if your lights are functioning is important for vehicle maintenance but is not the reason for signaling during maneuvers. Enhancing vehicle styling has no relevance to the function of turn signals, as their design is primarily focused on visibility and communication rather than aesthetics. Lastly, while making driving enjoyable is a factor in various aspects of driving, turn signals are specifically meant to convey intentions and improve road safety rather than contribute to overall enjoyment.
