Signals are normally given by direction indicators and which of the following?

Brake lights are an essential vehicle safety feature that communicates the driver's intentions to other road users. When a driver brakes, the brake lights illuminate, signaling that the vehicle is slowing down or stopping. This action is crucial for maintaining safe distances between vehicles, especially in situations where sudden stops may occur. Proper use of brake lights enhances overall road safety by alerting drivers behind you to your actions, reducing the risk of rear-end collisions.

While hazard lights, headlights, and side mirrors play roles in vehicle communication and visibility, they do not serve the primary purpose of indicating a stopping motion or the intention to reduce speed, which is the specific role of brake lights. Hazard lights indicate a stationary vehicle or warn of a potential hazard, headlights are primarily for illumination, and side mirrors are used for visibility but do not signal intentions. Hence, brake lights are the correct choice for signaling slowing or stopping actions on the road.
