About overtaking as a cop.

[Moving Coil]

http://forum.city-driving.co.uk/showthread.php?tid=4912 As I saw in this report there is a something that you can't overtake behind barriers. I didn't know this so I looked at the rules and didn't saw anything about it.

It says "Driving on the wrong side is tolerated for short periods of time and as long nobody else gets disturbed or endangered." But it also says "Cops must obey road laws when not in a chase." I didn't find the road laws anywhere either and if its about the real road laws I don't think there is such a law that says you can't overtake behind barriers.

If this is something like "don't drift the roundabout" rule, something everybody know and wasn't in the rules. Please add it to rules.
