When are you required to use turn signals?

• A. You only turn left
• B. You turn, change lanes and move from a straight line
• C. You turn in city traffic
• D. Traffic is following you

Answer: (B)

Using turn signals is a critical part of safe driving practices as they communicate your intentions to other road users. The correct choice emphasizes that you are required to signal not only when you are making a turn but also when changing lanes and when moving out of a straight line. This is important because it informs those around you of your movements, allowing for better prediction of your behavior on the road and enabling others to adjust accordingly, which enhances overall road safety.

In many jurisdictions, the law mandates the use of turn signals in these situations as a means to prevent accidents and improve traffic flow. For instance, signaling when changing lanes is essential because the vehicle you intend to merge in front of may have a different speed. Similarly, signaling when moving out of a straight line alerts other drivers and cyclists who may be unaware of your intentions.

Other options, while mentioning scenarios related to vehicle movement, do not cover the complete range of situations where signaling is required. This choice adequately encapsulates the comprehensive nature of turn signal use, reinforcing the responsibility drivers have to communicate their actions on the road.
