Visual explanation · Motorway merge
The first gap is gone
Question recap: Your first motorway gap closes while another gap develops behind it.
Correct answer
Adjust your speed to reach a gap that fits.
Why this is correct
Traffic moves while you prepare. Changing the target gap can be appropriate when the original space disappears.
Adapt your speed smoothly within the remaining lane and the traffic ahead. Check mirrors and the blind area before merging; motorway traffic must be allowed to continue unhindered.
