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

The icon is unambiguously a RED border on a WHITE background, with a black car overtaking a red car.
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.
✓ At the F1 sign (no overtaking) you may also not overtake an agricultural vehicle.
Pressure from following traffic is not a recognised exception to the F1 sign.

Correct answer: At the F1 sign (no overtaking) you may also not overtake an agricultural vehicle.

Explanation

F1 prohibits motor vehicles from overtaking EACH OTHER; agricultural vehicles may still be overtaken at this sign

The icon is unambiguously a RED border on a WHITE background, with a black car overtaking a red car. Red border = prohibition sign, like the rest of the F-series (F1-F4)
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. The traffic jam is only one of them
