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.
Explanation
trap: 'all vehicles' assumed where the sign only bans motor-vehicle-on-motor-vehicle overtaking. Book p.145 - F1 prohibits motor vehicles from overtaking EACH OTHER; agricultural vehicles may still be overtaken at this sign
