When must you use your turn signals?

Using turn signals is a critical aspect of safe driving that communicates your intended actions to other road users. The correct answer indicates that turn signals must be used both when turning and when changing lanes. This is essential to notify drivers and pedestrians of your plans, reducing the likelihood of accidents and misunderstandings on the road.

When you are making a turn or changing lanes, signaling serves as a warning to those around you, allowing them to react appropriately. This practice promotes a predictable traffic environment, which is particularly important in busy areas or on highways where the speed and volume of traffic are higher. Additionally, it fosters courtesy and respect among drivers, contributing to overall road safety.

In contrast, only signaling when changing lanes on highways limits the situations in which drivers communicate their intentions. Not signaling when other cars are nearby does not account for the many driving scenarios where drivers may need to be aware of your actions long before you actually execute them. Lastly, while signaling at a stop sign may seem prudent, it is not specifically mandated; it is more crucial to signal for the actions that impact others, like turning or lane changes.
