Mirrors - MSM
A manoeuvre is a change in speed, position or direction. Before you perform a manoeuvre you must first check your mirrors, then signal, then manoeuvre - Mirror, Signal, Manoeuvre.
When turning right, you must check your rear view mirror and your right wing mirror. These mirror checks are important, especially if you're altering your position drastically for the turn. An early mirror check will inform if it's safe to go and when you should put your signal on.
Warning - Failure to check mirrors could result in dangerous mistakes. It's important to know what's going on around you in case you need to react to other vehicles.
