Side mirrors, otherwise known as wing mirrors, are crucial to maintaining good visibility around you on the road. Importantly, they inform you of where a cyclist may be in traffic when your rear-view mirror might not have picked them up. Unfortunately, wing mirrors are prone to damage. Should this happen, it may not appear a major priority but legally you need two working mirrors and one must be on the driver’s side. A damaged mirror dramatically reduces your visibility and affects the safety of other road users. Fixing a wing mirror can cost from £15 to £150, so it isn’t worth taking the risk and landing a hefty fine of up to £2,500.
