Sign L403: The acceleration/merge lane continues as a through lane
Legal meaning
Acceleration lane becomes a through lane (information sign from the CROW sign register, not an RVV annex 1 sign).
Shape and colour
Blue rectangular sign with white lines where the merge lane continues as a lane: merge lane becomes a lane.
Where the sign stands

What the exam asks about this sign
The question is how it differs from an ordinary merge lane: this lane does not end but becomes a full lane, so you need not merge and traffic on the main carriageway need not make room. Trap: candidates look for a gap to merge and brake needlessly.
