In the situation presented, does the visible sign warn you of a dangerous bend to the right?

In the video you are driving on a road through fields outside a town; on the right there is sign A-1 "dangerous bend to the right" - a yellow triangle with an arrow curving to the right. It warns of a dangerous bend to the right. The answer is: yes.

The Regulation on road signs and signals states that sign A-1 warns of a dangerous bend in the direction shown on the sign; its mirror image, A-2, warns of a bend to the left. The sign is placed before a bend that is sharp or hard to see - on roads where you may drive faster than 60 km/h, at a distance of 150 to 300 m before the bend, and on other roads up to 100 m before it. Warning signs require road users to exercise particular caution, so you reduce your speed while still on the straight, before entering the bend, and you drive through the bend itself steadily, without braking, looking at where you want to come out. The Road Traffic Act also prohibits overtaking a power-driven vehicle on a bend marked with warning signs, and on such a narrow two-way road the roadway turning right hides what is coming from the opposite direction.

Legal basis: § 4 para. 1 and § 3 para. 1 and 2 of the Regulation on road signs and signals; Art. 24 para. 7 point 2 of the Road Traffic Act (Prawo o ruchu drogowym)
