Poor mirror use is a top fault on driving tests. Learn when, why, and how to use mirrors correctly.
Failing to check mirrors is one of the most common causes of serious driving test faults. The Mirrors-Signal-Manoeuvre (MSM) routine must become completely automatic. This guide explains when, where, and how examiners expect you to use your mirrors.
MSM stands for Mirrors — Signal — Manoeuvre. Before any change of direction, speed, or position, you must check your mirrors first. The order matters: check mirrors, THEN signal, THEN act. Signalling before checking mirrors is a fault because you might have signalled into the path of an overtaking vehicle.
