What is the purpose of activating your signal before passing?

Activating your signal before passing is primarily intended to warn other drivers of your intentions. When you signal, you communicate to other road users that you plan to change lanes or pass them, which is essential for maintaining safety on the road. This action helps to alert drivers behind you and in adjacent lanes, allowing them to anticipate your movement and adjust their speed or position as necessary.

Clear and timely signaling is a key component of defensive driving and helps to prevent misunderstandings that could lead to accidents. Being predictable on the road enhances safety for all, as other drivers can make informed decisions based on your intentions.
