Mirrors. All mirrors should be used effectively throughout your journey. You should
- use your mirrors frequently so that you always know what is behind and to each side of you
- use them in good time before you signal or change direction or speed
- be aware that mirrors do not cover all areas and there will be blind spots. You will need to look round and check.
Remember: Mirrors – Signal – Manoeuvre
