Waw, you have some stiff fines, almost everybody drives 150-160 on highway in Croatia, I did it too, so I risked 140 Euro?
(*)
For here - we have here two kinds of "penalty points", and the rules (as far as I remember) are:
1. "puncte amenda" - these are those mentioned by Alexu7, now a penalty point is 100RON (a little more than 28 euro). Note that Alexu7 mentioned the minimum fine, you can get a higher fine too depending on the policeman(i.e. "the severity of the contravention"). The good news is that regardless of the fine, by law you always get the option to pay half of the
minimum fine (not "your fine") on the spot, or within max. 24 (or was it 48?) hours. Also, if the policeman is nice, he may give you just a written "Warning" (no fine, but it includes "puncte penalizare").
2. "puncte penalizare": when you collect 15 of these points within 6 months, you get you license suspended for 3 months. If you do it again within a year or so, the second time it gets suspended for 6 monts
be careful though that you can easily get you license suspended directly by a large variety of other "actions" - e.g. crossing on the red
or yellow light, taking over in an area where it is forbidden (e.g. continuous line or explicit sign dissalowing this maneuver), going on in a forbidden dirrection (e.g. making a left when it is compulsory to turn to the right) etc.
