Ok. Thank you for explanation.

In a built-up area you may choose the lane that best suits your destination

Can be left if you want to turn left somewhere ahead
Can be left if you don't want to mingle with traffic slowing down to turn right in the right lane

There are no set rules, so you can simply remain left is that suits you ...[u] if there are at least 2 lanes in either direction[/u] or 1 way road

Hello, I found it's confusing where to drive within built up area when we have two lane in each direction.

Lesson 2 (question 12)says : within built up area you have two lane in your driving direction. Can you continue to drive in left lane : [b]Answer is yes, if you want to turn little further to left of park on left.[/b]

Lesson 15-16 ( question 25) : in built up area blue car continue to drive in left( in two lane in each direction) : answer is [b]Answer is this is permitted.[/b]

Please clarify.
Regards.
