Regs: i was driving down dominon road yesterday and was looking at the road markings. the bus lane is clearly marked as such, but the line between 'lanes' is a solid white line, not a broken white line. Is it even a legitimate lane for cars to travel down (been a while since i checked road code)? If not then the other car shouldnt be passing you in it.

"Some special vehicle lanes operate 24 hours a day for the use of the designated vehicles. Others have times of operation specified on their signs, for example, '4 pm to 6 pm'. In that case, you may be able to stop in them outside of these times"
"may be able to stop in them" - i.e. not drive in them. Probably a good idea to clarify that.
The picture on Page 1 also shows the solid white line. In that case, neither car should be in it.
