Philadelphia Drivers License Practice Test

When navigating a straight road, when is it necessary to use turn signals?

1. Only when passing other vehicles.

2. Only when the car is stopped.

3. When changing lanes or turning.

4. It is never necessary on straight roads.

The correct answer is: When changing lanes or turning.

Using turn signals is essential for communicating your intentions to other drivers on the road, particularly when you are changing lanes or making a turn, even on straight roads. This practice promotes safety by providing clear signals to others about your upcoming actions, allowing them to react appropriately. When you change lanes, signaling alerts drivers nearby of your movement, reducing the risk of accidents. Similarly, if you're about to turn while navigating a straight portion of the road, using your turn signal helps inform surrounding vehicles and pedestrians, ensuring that everyone on the road is aware of your actions. Failure to signal can lead to misunderstandings and increase the likelihood of collisions, as other drivers may not anticipate your movements if you're not clearly communicating them. This is why proper use of turn signals is a critical aspect of safe driving, regardless of whether the road is straight or curved.
