A manoeuvre is a change in speed position or direction. In driving, you are doing manoeuvres all of the time. The procedure, Mirror, Signal, Manoeuvre (MSM) should be applied to every manoeuvre. When turning left, which mirrors should you check at the start of your MSM routine?
Which mirrors should you check and why. Before turning left, you should first check your rear view mirror and then your left mirror to be sure that it is safe to turn. It will also help you decide when to signal.
Your mirrors should be used well before you signal or change direction or speed.
Remember: Mirrors - Signal - Manoeuvre - HC rule 161.
