Core: Solid line: main rule, two exceptions, and the gore area

A solid line not running along the road edge may not be crossed, and with two-way traffic you may not even be positioned to the left of that line. At a double line (one solid, one broken side by side) only the line on YOUR side decides — not the line on the far side, however close it looks. The second exception lets you cross the line specifically to reach or leave a breakdown bay, hard shoulder or peak-hour lane — not a general licence, only that one manoeuvre. A gore area or nose marking is never a lane: driving or stopping on it is forbidden, even in a jam. Only someone following a peak-hour lane, or lawfully a bus lane passing a split or merge, may briefly cross it. And all these markings are themselves binding traffic signs — a line with no sign next to it is just as mandatory as a line with one.
