What is the main purpose of using mirrors in a vehicle?

Using mirrors in a vehicle primarily serves the purpose of providing visibility of surroundings and other vehicles. This visibility is crucial for safe driving, as it allows the driver to be aware of blind spots, adjacent lanes, and what is happening behind the vehicle. Proper use of mirrors enables safe lane changes, turns, and reversals by giving drivers the information they need to make informed decisions on the road.

While other choices may mention related functions, they don’t align with the fundamental role that mirrors play in enhancing safety and awareness during vehicle operation. For instance, while mirrors might contribute to aesthetic appeal, that is not their primary function; similarly, they do not enhance audio systems or assist in parking exclusively, though they can be valuable tools for parking when used alongside other techniques.
