How does a driver signal for a right turn?

Using the right turn signal about 30 meters before making the turn is the correct approach. This practice provides adequate notice to other road users, including drivers and pedestrians, about your intention to turn. Signaling early gives others enough time to react, helping to ensure safety on the road.

The rationale for signaling in advance lies in the principle of visibility and predictability in traffic. By indicating your intent well ahead of the turn, you contribute to a smoother flow of traffic and reduce the likelihood of sudden maneuvers, which can lead to accidents.

In contrast, signaling only when in the intersection might not provide sufficient warning for others, increasing the risk of collisions. Honking the horn is generally reserved for alerting others to immediate danger, not for signaling turns, and making eye contact with pedestrians does not effectively communicate your intention to turn to all road users.
