Polish Road Signs and Traffic Sign Meanings

The T-20 sign indicates how far a prohibition, like a speed limit, will last.

T-20 - Length of Prohibition Polish road sign meaning

The T-20 supplementary plate, often seen with signs like 'Speed Limit' or 'No Stopping', clarifies the exact distance over which a restriction applies. For instance, if you see a speed limit sign with a T-20 plate showing '↑ 500 m ↑', it means the lower speed limit is in effect for exactly 500 meters from the sign. This sign is crucial for understanding temporary restrictions in Poland and helps drivers know precisely when they can resume normal driving behaviour, which is vital knowledge for the theory exam.

Understanding the Length of Prohibition Sign (T-20)

The T-20 'Length of Prohibition' sign is crucial for understanding distance-based restrictions in Polish traffic law. Learn its specific meaning to correctly interpret prohibitions and avoid penalties during your driving theory test.

Definition of T-20

The T-20 plate is used with prohibitory signs like B-33 (Speed limit) or B-36 (No stopping). It looks like '↑ 500 m ↑'. It tells the driver that the rule starts at the sign and ends exactly after the specified distance. This is often used on stretches of road between intersections where a specific risk (like a school or a narrow bridge) requires a lower speed limit for a short, defined period.

Meaning of T-20

Indicates the distance over which a restriction (like speed or parking) applies.

Allowed actions for T-20

Using your trip odometer to track when the restriction endsMaintaining the required behavior (e.g., staying under 40 km/h) for the full distanceResuming normal rules once the distance is clearly exceeded

Prohibited actions for T-20

Resuming normal speed before the indicated distance has passedParking 100m after a 'No Parking' sign with a '200m' plateIgnoring the restriction because the 'reason' for it isn't immediately visible

T-20 - Length of Prohibition road sign FAQ

Get clear, practical answers to the most common questions about the T-20 - Length of Prohibition 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.

What does the T-20 'Length of Prohibition' sign mean?

The T-20 sign is a supplementary plate used with prohibitory signs. It indicates the specific distance, typically in meters, over which the main sign's restriction (like a speed limit or no stopping zone) is active. The prohibition starts at the sign and ends after the specified distance.

How do I know when a prohibition ends if I see a T-20 sign?

You should pay close attention to the distance indicated on the T-20 plate, often shown with upward arrows on both sides (e.g., '↑ 500 m ↑'). You can use your trip odometer to track the distance covered since passing the sign. Once you have travelled the specified distance, the restriction automatically ends, and normal rules apply.

What are common mistakes learners make with the T-20 sign?

A common mistake is assuming the prohibition ends at the next intersection or simply guessing when it might be over. Learners might also incorrectly assume the restriction continues indefinitely or ignore it because the reason for it isn't immediately obvious. Always adhere to the stated distance on the T-20 plate.

Can I resume normal speed before the distance on the T-20 sign is covered?

No, you must maintain the imposed restriction, such as the lower speed limit, for the full distance indicated by the T-20 plate. Resuming normal speed before reaching the end of the specified distance is a violation and could be an exam trap. The prohibition is only lifted after you have travelled the full measurement.

Is the T-20 sign used with all types of prohibitory signs?

The T-20 sign is most commonly used with signs that impose a temporary restriction over a distance, such as 'B-33 Speed limit' or 'B-36 No stopping' or 'B-35 No parking'. It's designed to manage traffic flow and safety on specific road segments, like those between junctions or near hazard areas.
