Convex mirrors are preferred as a rearview mirror in vehicles as: 

  • i) It forms an erect (Rigidly upright or straight.) image of an object hence object becomes easily identified. 
  • ii) It forms a diminished image of the object thus increases the field of vision.
  • iii) An object that is far away from us is seen closer which helps us to take early decision while driving.
