Does this line indicate the place you must stop before entering the intersection?

Before the junction there is sign B-20 "STOP", and on the roadway you can see a thick, solid transverse line - the mandatory stop line P-12. It shows exactly the place where you must stop before entering the junction.

The STOP sign prohibits entering the junction without stopping before the priority road, and the Regulation on road signs and signals adds that you should stop at the place marked for this. This place is line P-12. You always stop before it, regardless of whether anything is coming along the priority road.

Legal basis: § 21 para. 1 and 2 and § 89 para. 1 of the Regulation on road signs and signals
