Hello,
Could someone explain me the meaning of these signs? Which are bus lanes and which are not?

I'm referring to question 8739 of the exam.
F17 and F18 signs on this page.

Thank you in advance.

Sign 1 = Bus lane
Sign 2 = Specific reserved route
Sign 3 = Specific reserved route

See explanation and rules in your book p. 136 (specific reserved route) and 138 (Bus lane)

Thank you so much
