Think, if one little thing can save your life, why ignore it? Bike side mirrors – no more valuable than you and your loved ones. The side mirror is not just a mirror, but a means of protection. Without side mirrors, it becomes difficult to keep track of oncoming traffic. This can cause accidents while cutting turns, changing lanes, or stopping. Without side mirrors, your reckless driving can also be dangerous to others. The act of looking back before changing lanes can reduce accidents.
