Driving is straightforward generally and signs are easy to follow. Keep in mind that police cars do not typically pull you over. If police are on duty they usually keep their lights on. Instead of pulling you over for a violation, they will put cones in the middle of the road and force you to slow down and pull over. If they stop you, most likely you were caught several km back by an officer you didn't see with a radar gun or something.

Another confusing thing is that cars typically pull directly into roundabouts and then the cars inside the roundabout need to yield to oncoming traffic. Sometimes there are even traffic lights inside the roundabout. So just be aware.
