The exam asks who may enter: nobody with a vehicle, not even a cyclist, unless a plate makes an exception. Pedestrians may. Do not confuse with C2: C1 applies in both directions, C2 only from this side. Typical question: 'except cyclists' on the plate — then you may enter by bike.
Trap
Reading C1 and C2 as the same closure.
C1 closes BOTH directions; C2 closes only this direction of a one-way road.
Exam question on this sign
On a provincial road you pass, in short succession: a round 'C1 closed in both directions' sign and, a hundred metres further, the round overtaking-ban sign. A passenger says: 'So those are two C-signs.' Is that correct?
Yes — both are round with a red border, so both are category C
No — only the first is category C; the overtaking ban is category F
No — neither is category C, because both are actually category F
Show the answer
Correct answer: No — only the first is category C; the overtaking ban is category F
Why learners get this wrong: The overtaking-ban sign (F1) belongs to category C, because it is a round sign with a red border like the other prohibition signs.
