When are you required to use turn signals?

Using turn signals is a critical aspect of safe driving, as they communicate your intentions to other road users. You are required to use turn signals whenever you are changing direction or lane, which includes making turns, merging into another lane, and any situation where your trajectory is altered. This helps maintain safety on the road by alerting drivers and pedestrians to your movements, allowing them to anticipate and react appropriately.

The requirement for turn signals is not limited to specific actions, such as just changing lanes or turning left. It's important to signal all directional changes to ensure comprehensive communication with others. Moreover, treating turn signals as optional can lead to confusion and increased risk of accidents, as other drivers may not be able to predict your actions if you fail to signal properly. Therefore, turn signals are an essential tool in promoting road safety.
