When are you required to turn on your signals?

You are required to turn on your signals 100 meters before making a turn or changing lanes to notify other road users of your intentions. This distance allows sufficient time for nearby drivers and pedestrians to understand your planned action, facilitating a safer driving environment.

Using your signals well in advance is essential in preventing accidents, as it gives others ample time to react. For example, if you are about to change lanes on a highway, signaling 100 meters ahead allows other vehicles to maintain a safe distance or adjust their speed accordingly. This practice helps ensure that all road users are aware of your movements, promoting a cooperative traffic flow.

The other options do not provide the correct guidelines for effective signaling. Only signaling in residential areas or during night driving would not account for situations in various environments and conditions where signaling is crucial. Similarly, relying solely on the presence of nearby drivers does not establish a clear protocol for signaling your intentions, which should be done consistently regardless of the immediate situation.
