When are you required to use turn signals?

Using turn signals is an essential safety practice for communicating with other road users your intentions while driving. The requirement to signal when changing lanes, turning, or merging is rooted in the need to provide clear and timely information to other drivers, cyclists, and pedestrians. This practice helps prevent accidents by ensuring that everyone is aware of your movements on the road.

By signaling when changing lanes, you are indicating that you plan to move into a different lane, which allows other drivers to adjust their speed or position accordingly. When making a turn, signaling informs others of your intention to leave the roadway or transition from one direction to another. Similarly, using signals when merging helps to facilitate a smoother flow of traffic as vehicles enter or exit roadways.

While there are other situations where it may be beneficial to use turn signals, such as at intersections or during nighttime driving, the primary requirement involves the actions of changing lanes, turning, or merging, making it crucial for safe driving practices.
