Warning line and solid line (M11)
”This marking is used where it is not permitted for a vehicle on the side of the solid line to change lanes. The marking can also be used to indicate an oncoming solid line on the side where there is a warning line.”
Since the line is solid on your side, you may not normally cross it.
There is also a driving licence book online (2022).
