Tennessee Permit Practice Test

Which of the following is a reason to use your turn signal?

1. To alert other drivers of a lane change

2. To indicate you are lost

3. To communicate frustration with other drivers

4. To ignore traffic laws

The correct answer is: To alert other drivers of a lane change

Using your turn signal is essential for safe driving and smooth traffic flow. One primary reason for signaling is to alert other drivers of your intention to change lanes. When you activate your turn signal before making a lane change, it communicates to surrounding vehicles what you plan to do, allowing them to adjust their speed or position accordingly. This can help prevent accidents, as other drivers are given a clear warning that you are about to move into their lane. The other options do not align with the purpose of using turn signals. Indicating you are lost with a turn signal can confuse other drivers and does not effectively communicate your situation. Communicating frustration is not constructive for safe driving and further contributes to road rage scenarios rather than traffic safety. Ignoring traffic laws is not only dangerous but can lead to legal consequences, and using a turn signal is very much about adhering to those laws. Therefore, using your turn signal to alert other drivers is the correct and safe practice when changing lanes.
