Rear-View and Side Mirrors

The centre rear-view mirror (control 1) and side mirrors (control 3) must be checked first, before any change of speed, direction or braking — the manual’s core ‘mirrors first’ instruction. The motorcycle equivalent is the mirrors (control 3). Underpins safe Overtaking and lane changes.

Evidence note: Official NaTIS Section 3 numbered control. evidence_strength: confirmed.

Purpose

Let the driver see traffic to the rear and sides to build awareness before acting.

When used

Checked BEFORE changing speed, direction or braking — the manual’s standing rule.

Risks of incorrect use

  • Blind-spot collisions
  • Unsafe lane changes

Question patterns

  • “Which control performs function X?” — component identification.
  • Distractor trap: Checking mirrors after manoeuvring instead of before.
