What is the minimum diameter for each convex mirror?

The minimum diameter for each convex mirror used in Maryland is 12 inches. This specification is important as it ensures adequate visibility and coverage for the area being monitored. A mirror of this size provides a sufficient field of view, reducing blind spots and enhancing safety in various environments, such as parking lots or roadway intersections where the convex mirrors are typically installed. The requirement for a 12-inch diameter reflects compliance with safety regulations designed to improve driver awareness and prevent accidents. This size strikes a balance between visibility and practicality, ensuring that the mirrors fulfill their intended purpose effectively.
