It's a key indicator for adjusting your driving behaviour in Poland.
The D-42 Built-up Area sign fundamentally changes driving rules, imposing a 50 km/h speed limit and altering parking and honking regulations within Polish towns. Understanding this road sign meaning is vital for passing your driving theory exam and ensuring safe navigation through urban traffic, reflecting official Polish traffic rules.
The D-42 sign shows a black silhouette of a city skyline on a white background. It defines the legal boundary of a built-up area (Obszar zabudowany). From this point forward, the general speed limit is 50 km/h (unless otherwise posted). This sign also changes rules regarding honking (prohibited except for danger) and parking. It is a crucial marker for road safety, as it signals a higher density of pedestrians, intersections, and property entrances.

Get clear, practical answers to the most common questions about the D-42 - Built-up Area road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the Polish driving theory exam in Poland.
The D-42 sign indicates the start of a built-up area, and its primary effect is to lower the default maximum speed limit to 50 km/h. You must ensure your speed does not exceed this limit from the moment you pass the sign, unless a lower speed limit is explicitly indicated by another sign.
Yes, while the D-42 sign sets a default limit of 50 km/h, other traffic signs might override this. You may encounter signs indicating a higher speed limit (e.g., on main roads entering a larger city) or a lower speed limit (e.g., in school zones or areas with specific hazards).
Besides the speed limit, the D-42 sign also affects other rules. Honking is generally prohibited in built-up areas unless it's an immediate danger warning. Parking regulations may also change, and you should be more vigilant for pedestrians, cyclists, and children who are common in these zones.
While a town name sign (E-17a) might show you are entering a town, it doesn't automatically change the speed limit. The D-42 sign is the official marker that legally establishes the built-up area and enforces the 50 km/h speed limit. You must slow down only when you see the D-42, not just the town name sign.
A common trap is assuming the speed limit changes when you see the town's name sign (E-17a) rather than the D-42 'Built-up Area' sign. Another trap is forgetting that the 50 km/h limit applies immediately after the D-42 and not paying attention to potential signs indicating a different speed limit, especially at junctions.
