When should you use your turn signal while driving?

Using your turn signal at least 100 feet before making a turn is critical for safe driving and effective communication with other road users. This advance notice allows other drivers, pedestrians, and cyclists to anticipate your actions and adjust accordingly, thus minimizing the risk of collisions.

The requirement to signal well ahead of a turn ensures that the signal has enough time to inform those around you of your intent to change direction. It is essential for maintaining safety and providing adequate warning to motorists who may be following closely behind or approaching from other directions.

In contrast, signaling at the moment you begin the turn does not give other drivers enough time to react, which could lead to accidents. Not signaling only when other vehicles are present may lead to a misunderstanding of your intentions, and failing to use a signal when entering or exiting a highway neglects a critical aspect of highway safety protocols. Thus, the correct practice is to use your turn signal well in advance of making a turn to ensure clarity and safety on the road.
