# Explanation
At a road narrowing without priority signposting, **the basic rule is that the vehicle that entered the narrow zone first has right of way**. This rule avoids conflicts and maintains traffic flow in an orderly manner. The vehicle that arrives later must give way and wait for the first one to complete its passage before driving.
