What is not an advantage of side mirrors?

Answer: C — Seeing what's in front of the car

The correct answer highlights that side mirrors are not designed for the purpose of seeing what is in front of the car. Instead, their primary functions include providing drivers with visibility of areas behind the vehicle and assisting in detecting vehicles in blind spots, which is crucial for safe lane changes. Understanding the limitations of side mirrors is essential for safe driving practices. They enhance the driver's awareness of surrounding traffic and potential obstacles, but they do not provide a clear view of what lies ahead. This distinction is important for effective vehicle operation and maintaining safety on the road.
