About Overtaking: the F1 sign and the five exceptions to left-overtaking: which statement is WRONG?

There are FIVE exceptions: right before/at roundabouts, driving to the right of a block marking, overtaking a traffic jam, a driver who has signalled left and pre-sorted left, and overtaking a tram.
F1 prohibits motor vehicles from overtaking EACH OTHER; agricultural vehicles may still be overtaken at this sign.
✓ Overtaking at a pedestrian crossing (zebra crossing) is only prohibited if there is a no-overtaking sign.
The icon is unambiguously a RED border on a WHITE background, with a black car overtaking a red car.

Correct answer: Overtaking at a pedestrian crossing (zebra crossing) is only prohibited if there is a no-overtaking sign.
