That is OK as long as you have your left turn signal on
I think that will be too early to put on the signal, for instance here in my home town, coming into town on the highway from the south, about 1000 M before the road cross the rives where there are 2 left turn and 2 right turn lanes, then i am in the left lane as soon as the 1 lane turn into 2 lanes.
I could stay in the right lane most times of the day and then change to the left lane about half way, but in peak hours then 350 M after the road go 2 lane there is a intersection, and you want to be in the left lane there cuz both lanes back up, and when released by green light cars dot get to space out before the next intersection in 450 M and then after that, and on the other side of that the 2 lanes turn into the 4 turn lanes on the bridge over the river.
As i said i keep up to speed, actually in my little car i often leave the other people behind as i accelerate faster, so the issue are not me hoggin the lane forcing people to drive slow, i think the issue are entitled people want ownership of that lane so they can pass the rest of us, even if that mean braking the speed limit passing us other drivers in the right lane.
If some one can guarantee me that i will not be passed by lawbrakers as i keep left, then sure no problem, but that's not going to happen and further up those people will force their way into the Left lane as traffic there are already bumper to bumper, and so you cant really overtake as the law state you can only do that when it dont inconvincible other motorists, and if people have to brake all the time to let people into a already filled and probably slow moving lane well then to me that are a inconvenience.
I know we are supposed to give way to one and other and be nice, but i really dont want to do that with people braking the law zooming past me to get 2-3 cars lengths ahead of me.
I feel Danish law are faulty on this, cuz if all drove according to law then we would have empty Left lanes all over the country, cuz you cant legally pass people driving bumper to bumper at the max posted speed.
You could then argue well people shouldent drive bumper to bumper, and that's true, but try telling that to Danes or the people who should uphold our laws.
Clearly as it is at the moment we Danes cant handle it on our own and we invent our own addon traffic rules, and that are unsustainable for sure, so i argue for rule change and stronger enforcement of those rules.
