In most cities on a 2 lane city street it is illegal to pass.
Any turn going left from any of the right lanes is an illegal turn. However, if you signal into any of the two left lanes (assuming the white lines are dashed and not solid), you can make a legal left turn from any of the two left turn lanes.

From the lane nearest the right hand curb into the lane nearest the right hand curb -UNLESS of course - making a LEGAL left hand turn into a one-way street. Then it would be from the lane closest to the left hand curb into the lane nearest the left hand curb.
