Can you overtake the vehicle in this situation?

Why?

Overtaking the car ahead would require crossing or driving onto the double solid centre line P-4, which is prohibited. A warning sign also indicates dangerous bends ahead. Stay behind the car until you reach a section where overtaking is both permitted and safe.

P-4 „linia podwójna ciągła”, § 86 ust. 5 rozporządzenia w sprawie znaków i sygnałów drogowych
