Penalty for “Ghost Dangers”

Hello guys, I have a question I was on the road in the city today and mistakenly assumed that the road on which I drive is 2 lanes (so the 2 lanes go in one direction, net only one… asks me why, maybe because I drove the time before the highway or anyway.) in each case I switched to the left lane to turn left in 100m.. now this was not the left lane, but the opposite lane My question is now how high is the number of lanes. the punishment for such misconduct is (no one was harmed, the road was clear, otherwise I would have noticed that there was nothing wrong, only a driver who wanted to leave the exit looked stupid) Thank you already!
