Why Replacement of Broken Side Mirrors Are Important? Side mirrors are used more than you think, every time you’ve got to change lanes, reverse into a spot or before opening your door when you want to step out. Importance of side mirrors is often overlooked as we spend conscious effort into steering, accelerating and braking but not so much in glancing at the side mirrors for information. A damaged engine, a punctured tire or a cracked windshield is repaired instantly but a broken side mirror is often overlooked if you can still barely see out of it. Now you don’t want your mirror to fall out on the road when you’re commuting or break even more when you’re adjusting the angle to see better.
