Turn signals are a crucial safety feature in driving, serving the specific purpose of indicating your intention to turn or change lanes to other drivers. When you activate your turn signal, you communicate your upcoming maneuvers, allowing other road users to anticipate your actions and respond appropriately. This reduces the risk of collisions and enhances overall road safety.

The other choices do not reflect the primary function of turn signals. For example, while alerting emergency vehicles may involve other signals or lights, it is not the main role of turn signals. Similarly, while it is important to signal your vehicle's speed changes or to alert pedestrians at times, these actions are not the primary intention of turn signals, which are specifically designed to communicate turning or lane changing intentions.
