When should turn signals be used?

Turn signals should be used at least 100 feet before turning or changing lanes as this provides adequate warning to other drivers and allows them to react safely. Using turn signals in advance helps to communicate intentions clearly, ensuring that other road users are aware that you plan to change direction. This practice is essential for maintaining safety on the road, as it reduces the likelihood of misunderstandings or accidents caused by sudden lane changes or turns without signaling.

Using signals only at the moment of turning does not give other drivers sufficient time to respond. Similarly, limiting the use of signals to only when necessary may lead to situations where other drivers are caught off guard. Using signals exclusively at night fails to consider the importance of signaling during all driving conditions, as effective communication is critical regardless of the time of day.
