Left Turns Across a Median
A topic came up in local Reddit forum today, with an equal split of opinions, both sides being adamant that their approach is correct. When making left turns across a median, is it the red line that drivers should take or the blue one as shown in this image of Cambie Street and West 64th Avenue in Vancouver?

Question: If a novice driver is accompanied by someone over 25 who has a full class 5 license but is currently serving a 90 day immediate roadside prohibition, are they within the law? Does this count as an appropriate "Supervisor" ?
Question: I'm wondering what the offence is if I carry 3 passengers in a vehicle that's only equipped for two? If one passenger was seated on the floor / a box between the two installed seats? It's a 3 ton truck.
