A driver intending to use the acceleration lane to merge onto a motorway or dual carriageway, or any other road with an acceleration lane, must observe the traffic and stop the vehicle at the beginning of the acceleration lane if necessary, if merging cannot be done safely, and when the right moment comes, resume driving by accelerating until reaching the appropriate speed at the end of the acceleration lane in order to merge into traffic.
