To further muddy the waters, the UK has advisory cycle lanes (with a
broken white line) and mandatory cycle lanes (solid white line).

Mandatory in this context means that it is a requirement that motor
vehicles do not drive in the lane, not that it is mandatory for cyclists
to use them. There are no lanes where it is compulsory for cyclists to
use them.
