When riding a motorbike, can you overtake a passenger car beyond this sign?

Explanation
Correct answer: No
No. The B-25 'no overtaking' sign prohibits overtaking multi-track motor vehicles. A car is a multi-track vehicle, so overtaking it beyond this sign is prohibited. The ban applies to all drivers, including motorcyclists: a motorcycle rider must not overtake a car in the area covered by sign B-25.
