Traffic sign B19: Narrow passage: give way

The B19 sign stands before a narrow passage and means: let oncoming traffic through first. For a worksite that reduces the road to one lane, it stands on the side of the works. The B21 sign stands on the other side.

Priority signs decide who goes first. At roadworks they mostly appear where the carriageway is reduced to a single lane: B19 on one side, B21 on the other, so both directions know who has right of way.

Anyone who puts up a traffic sign on the public road for works needs the consent of the road authority: through the occupation permit or through a signage permit with a signage plan. Without that consent you may not put up the sign.
