When should you use your turn signals?

Using turn signals is crucial for safe driving, as they communicate your intentions to other road users. The correct choice emphasizes that you should signal before changing lanes, merging, or turning. This helps ensure that drivers around you are aware of your actions, allowing them to react accordingly and maintain safety on the road.

Signaling before these actions provides a clear and consistent message about what you intend to do, reducing the risk of accidents caused by unexpected maneuvers. It is a fundamental aspect of driving etiquette and legal requirements in Illinois and most other jurisdictions. By consistently using turn signals in this manner, you contribute to a safer driving environment for everyone.

Although signaling only when turning, when entering a roundabout, or in the presence of pedestrians is important in specific contexts, using turn signals before any significant directional changes encompasses all relevant situations and is the most comprehensive practice for effective communication on the road.
