This FAQ strengthens your understanding and supports accurate decision making for the Polish driving theory exam in Poland.

What does the D-55 'End of Clean Transport Zone' sign mean?

The D-55 sign means you are leaving a low-emission zone where certain vehicles might have been restricted. It signals that those specific environmental driving rules no longer apply on the road ahead.

What actions are prohibited when I see the D-55 sign?

A common mistake is assuming ALL traffic restrictions end with the D-55 sign; it only lifts the 'clean transport' environmental rules. You should not accelerate excessively in urban areas simply because the zone has ended, and always remain mindful of other traffic signs.

Can I now drive a restricted vehicle after passing the D-55 sign?

Yes, if you were driving a vehicle that was not permitted in the clean transport zone you just exited, you are allowed to continue driving it after passing the D-55 sign. The environmental restrictions from the previous zone are no longer in effect.

Does the D-55 sign mean all traffic rules, like speed limits, have ended?

No, the D-55 sign specifically marks the end of the 'clean transport' environmental zone only. General traffic rules, including urban speed limits (typically 50 km/h) and any other designated zones like 'Paid Parking' or 'Residential Areas', remain in effect. Always observe other posted signs.

What should I pay attention to after seeing the D-55 sign?

After passing the D-55 sign, you should check for any other signs that might indicate you are entering a different type of zone, such as a paid parking area or a residential zone. It's also important to re-evaluate your speed according to general urban limits if you haven't already.
