What is required inside all vehicles for visibility?

The requirement for a rearview mirror in all vehicles is rooted in the need for enhanced visibility and safety while driving. The rearview mirror plays a crucial role in allowing the driver to see directly behind the vehicle, which is essential for safe maneuvers such as changing lanes, reversing, and understanding the surrounding traffic situation.

This mirror helps minimize blind spots and contributes to overall situational awareness, which is vital for preventing accidents. Its presence is mandated by vehicle safety standards across many jurisdictions, ensuring that every vehicle is equipped with this critical component to promote safety on the road.

In contrast, while side view mirrors also help with visibility, they are not universally required inside the vehicle as a singular visibility feature. A dashboard camera and fog lights serve different purposes—dashboard cameras are used for recording, and fog lights are for driving in specific weather conditions—but do not satisfy the basic requirement for visibility mandated by law.
