The P-3 marking, known as the Unilateral Crossing Line, is crucial for regulating overtaking on Polish roads where conditions differ for opposing traffic. It consists of a solid line and a dashed line running parallel. You may only cross this line to overtake or return to your lane if the dashed line is on your side of the road and the manoeuvre can be completed safely.
This P-3 road marking dictates specific overtaking rules based on line type; learn its precise meaning and application to correctly navigate Polish traffic and prepare for your theory test revision.
This marking consists of a solid line and a dashed line running parallel to each other. It is designed to regulate overtaking in areas where visibility or safety is different for each direction of travel. For instance, a driver coming out of a sharp bend might have a solid line (no overtaking), while a driver entering the straight section from the other direction has a dashed line. A special exception allows a driver who started overtaking on the dashed side to cross back over the solid line to return to their original lane.
Allows crossing from the side of the dashed line, but prohibits crossing from the side of the solid line.
Get clear, practical answers to the most common questions about the P-3 - Unilateral Crossing Line road sign.

This FAQ strengthens your understanding and supports accurate decision making for the Polish driving theory exam in Poland.
The P-3 marking signifies a line where overtaking is permitted from one side but prohibited from the other. It consists of a solid line and a dashed line. You can initiate an overtake or cross if the dashed line is closest to your vehicle; however, you must not cross or overtake if the solid line is on your side.
You are allowed to cross the solid line part of the P-3 marking only to return to your original lane after you have legally completed an overtake that was initiated on the dashed line side. You must not initiate an overtake from the solid line side, nor cross it to access side roads or properties.
A common mistake is initiating an overtake from the solid line side, believing it's permitted if the dashed line is on the opposing vehicle's side. Learners might also mistakenly follow another vehicle that is overtaking from the dashed side, crossing the solid line without a clear understanding of the rule. Always check which line is on your side.
While the P-3 marking itself doesn't dictate a specific speed, the reason it's placed (e.g., bends, reduced visibility) often implies a need to adjust your speed. When the dashed line is on your side, you may overtake if safe, which might involve accelerating. If the solid line is on your side, you must maintain your speed and stay in your lane, respecting the prohibition on overtaking.
Yes, the P-3 is unique because it combines both a solid and a dashed line. A standard solid line prohibits crossing entirely, while a standard dashed line permits crossing for overtaking if safe. The P-3 line allows crossing for overtaking only from the side with the dashed line, creating a selective prohibition.
