Normally, you should use the interior mirror first followed by the exterior mirrors. Before carrying out any manoeuvre always check your mirrors. This includes: moving off - check all mirrors and look over your right shoulder to check the blind spot.
When should you check your mirrors when driving?
When and why you should use your mirrors: Before moving off to check it's safe to pull out into traffic. Before signalling to check you won't confuse a driver behind you. Before any change of direction including turning, overtaking and changing lanes.
Anytime you're changing lanes or merging, you'll want to check for any car blind spots in your driver view first. Flip on your turn signal to let other cars know you'll be moving over, and check your rear mirrors and sidecar mirrors. Finally, you'll want to do a quick shoulder check one last time.
