Free practice: Turning, signalling and changing lanes →Know what each lane needs to do
The driver in the lane that ends should signal, check the blind spot and enter an available safe gap. In the continuing lane, each driver should allow one vehicle to merge ahead. Alternating vehicles keeps both queues moving; it does not let a driver force another car aside.
Where two lanes feed a new single lane, both streams need to signal, shoulder check and take turns when safe. Identify the actual layout before deciding that only the driver on one side has work to do.

SGI says zipper-merge signs may be absent even where the method is allowed and recommended in construction zones. Their absence does not by itself require everyone to join one long queue early. Follow posted instructions and any directions controlling the work area.
A lane-closure merge is different from passing on a shoulder or using a lane closed to traffic. The method uses lanes that remain available up to the merge. Construction or maintenance vehicles operating warning lights also have right-of-way requirements in the handbook.

Original worked cases
Continuing lane: one car from the ending lane has merged ahead of you. Continue leaving room and let the next pair alternate at the merge. Closing the gap to punish a late-arriving car defeats the turn-taking method.
Ending lane: you reach the taper beside another vehicle. Signalling alone does not create a safe gap. Adjust position and speed, shoulder check and merge only when it can be done safely.
Two-to-one layout: neither original lane continues straight through. Both drivers need to check and signal; neither should assume the other stream must yield simply because of the side it started on.
Practise the lane decision and the observation step
For each practice question, identify which lane ends, whether a lane remains open to the taper, and whether the scenario supplies special signs. Then explain the signal, blind-spot check and alternating gap.
The free turning-and-lanes questions cover lane-change observations; right-of-way questions add work-zone decisions. Learn these alongside current SGI directions before supervised driving practice.
