What is the minimum distance a rear view mirror should allow the operator to see behind?

The minimum distance a rear view mirror should allow the operator to see behind is 200 feet. This standard is in place to ensure that the driver has a sufficient line of sight to monitor traffic and obstacles that may be coming from behind. By having a clear view up to 200 feet, the operator can make safer driving decisions, such as merging into traffic or reversing without unaware of approaching vehicles, enhancing overall safety. This distance is often considered a practical limit to balance visibility with the realities of driving situations.
