Lane Numbers

[firstmazda]

How are the lanes on the highways numbered?
I always hear on the traffic reports "Lane 2 is blocked" etc.

Is Lane 1 the passing lane? or does it start from the other side, the merging/on off ramp/grandma lane?

Numbered from the left.

Thanks, I was wondering the same thing.
