Not in the UK or the Netherlands at least. They can do whatever they see 
fit in the course of duty, especially with lights and sirens. Of course 
they can be called to account if anything goes wrong. But a policeman 
chasing a criminal who turns the wrong way up a one way street is going 
to follow them and is not going to take a longer route just because of a 
little no-entry sign. Maxspeed, turn restrictions, oneways, 
waiting/stopping/parking restrictions, traffic signals - you name it, 
they can (and do) ignore it when required (sometimes only under certain 
circumstances such as life-and-death).

Having said that there are certain restrictions which they would do well 
to follow, such as maxheight and maxwidth. If it don't fit, it don't 
fit, with or without blue lights!
