Where to position blind spot mirrors on your car

Blind spot mirrors (small circular mirrors) help eliminate visibility gaps. Optimal positioning depends on which rear view mirror you're fitting them to. For the left mirror, stick it in the top left corner to monitor the rear wheel - crucial when parallel parking near kerbs to avoid alloy wheel scrapes. Alternatively, placing it bottom left widens your lane view but sacrifices wheel visibility. Never fit the right mirror's blind spot aid top right despite wheel visibility, as it dangerously distorts distance perception - a car 3 metres back may appear deceptively far away, risking unsafe lane changes.

Blind spot mirrors should be positioned to maximise visibility while minimising obstruction. For the left mirror, fit the small convex mirror in the lower left corner to reduce blind spots and view the right wheel during parking. The right mirror offers more positioning options: lower left improves overtaking visibility, lower right helps gauge kerb distance when parking, but avoid the upper right as it obstructs view. These convex mirrors help monitor wheel and side body positions, though they don't eliminate blind spots during lane changes, especially at night. All mirrors must be adjustable to meet UK road safety standards.

Blind spot mirrors should be positioned on the upper outer corner of each wing mirror - left side for the driver's mirror, right side for the passenger side. This placement maximises visibility, reducing blind spots particularly when reversing. These small convex mirrors significantly improve safety by expanding your field of view.

Installing blind spot mirrors is straightforward. They use strong adhesive backing (typically 3M tape) and can be rotated to achieve the optimal angle after fitting. Proper adjustment helps eliminate dangerous blind spots without obstructing your main mirror view.

No legal approval is required for fitting blind spot mirrors in the UK. They're considered a safety enhancement rather than a vehicle modification, so you won't need to notify the DVLA or affect your MOT status. Many drivers find them especially helpful when parking in tight spaces or towing.
