The D-43 sign is the city skyline with a red diagonal line. It signals that you are entering a rural environment. For most vehicles, the speed limit increases to 90 km/h (for single carriageways). However, you should still be cautious of farm vehicles, wild animals, and hidden driveways that are common in rural Poland. This sign also marks where you can once again use your horn for purposes other than immediate danger, such as before overtaking in low visibility.

Road Slope Percentage

The T-9 plate is paired with A-22 (Dangerous descent) or A-23 (Steep climb). A 10% slope means the road rises or falls 10 meters for every 100 meters of horizontal travel. This information is vital for heavy vehicles (to choose the right gear for engine braking) and for all drivers in winter, as steep slopes become impassable or extremely dangerous when icy.
