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.

What does the D-51b 'Average Speed Check End' sign mean?

The D-51b sign means that the section where your average speed was being monitored by cameras has ended. You are now free from that specific speed check, and your journey through that controlled zone is complete.

What should I do when I see the D-51b sign?

Upon seeing the D-51b sign, you can resume normal driving. Ensure you are adhering to the current speed limit for the road you are now on, which may be different from the speed limit within the average speed check zone. Continue driving safely and be aware of any upcoming traffic signs or road conditions.

Can I accelerate immediately after the D-51b sign?

While the average speed check has ended, you should not accelerate dangerously. Always ensure your speed is legal and safe for the current road conditions and speed limit. Sudden, aggressive acceleration immediately after the sign could be unsafe and potentially attract attention.

Are there any specific exam traps related to the D-51b sign?

A common trap is assuming all speed restrictions are lifted. While the average speed check ends, the general speed limit of the road still applies. Learners might also mistakenly think they can speed up excessively once past the sign, forgetting that safe driving principles always apply. Always check for subsequent speed limit signs.

What if I stopped for a break inside the average speed check zone?

If you stopped for a break within the zone monitored by average speed cameras, your overall average speed for that section would naturally be lower. This is a key factor in how average speed is calculated. The D-51b sign simply marks the end of this calculation period, regardless of whether you stopped or not.
