This is traffic offense, not a criminal offense..

I think nobody knows about private property/road. Mostly private property/road is not gazetted under any authorities as public road, thus making any accident happens are at your own risk. You can go to Mardi and you can find a signage there saying private road, and driving on it was absolute at your own risk. And if you want to know, some of road parts of Genting Highland was also a private road..
