Getting the Most Out of the Rearview Mirror Specifically
Last reviewed: 2026 · Driviology Road Safety Education Team
Quick Answer
The rearview mirror should be positioned to frame the full rear window, with its anti-glare tab flipped at night to reduce headlight glare from vehicles behind, a specific setup step distinct from side mirror adjustment.
The rearview mirror gets its own dedicated setup steps, separate from the side mirrors covered elsewhere in this guide.
Correct Positioning
The mirror should be angled to frame the full rear window without needing to move your head, a baseline step within the broader routine covered in our guide to mirror adjustment.
Using the Anti-Glare Tab at Night
Flipping the small anti-glare tab at the base of the mirror at night significantly reduces headlight glare from vehicles behind, a feature specific to the rearview mirror rather than the side mirrors.
How It Complements the Side Mirrors
The rearview mirror covers the space directly behind, while blind spot mirrors and side mirrors cover the areas it cannot, together forming complete rear coverage.
