Turning, lane changes and passing →Use mirrors and a shoulder check together
Mirrors show much of the traffic beside and behind the car, but the handbook identifies areas to the rear left and rear right that mirrors may not show. A shoulder check addresses that missing view before a turn or lane change.
The check belongs in an ongoing scan. Do not stare at one mirror while losing track of the scene ahead. The question is whether the intended movement has a safe space, not whether you have completed a token head movement.

A vehicle two lanes away may also be preparing to enter your target lane. The handbook therefore asks you to examine that farther lane as part of the decision. A gap can disappear even when the car directly behind you stays in place.
After signalling, check again for a vehicle approaching quickly from behind. If conditions change, reassess rather than completing the move simply because you have already signalled.

Original learning cases
Your mirror shows a gap, but a vehicle is hidden beside your rear quarter. The shoulder check supplies information the mirror did not provide.
You want the middle lane while another car in the far lane also signals toward it. Check that competing movement before occupying the apparent gap.
You signal, then notice a rapidly approaching vehicle behind. Reassess the move; the signal did not reserve the lane for you.
Move gradually after the checks
The published sequence finishes with a slow steering movement into the new lane, maintaining speed or increasing it gradually. It does not call for a sharp sideways move. Prepare a required lane change before an intersection; the handbook says not to change lanes while travelling through one.
This is a lane-change reference. Passing a vehicle on a two-way road adds visibility, oncoming-traffic and return-gap decisions covered in the separate free passing article. A written exercise cannot assess your practical observation skills.
