There are many good tips in this and other driving threads. The top safety advice I would give is (in rough order of importance): 1) maintain at least two car lengths distance in all directions whenever possible to allow time to react to highly unpredictable local drivers
2) don't rely on or be distracted by horn honking as horns are used to signal presence more than impending hazard (there is only a fine distinction between the two on these roads) 3) beware of road hazards on the autopista such as people sat in lawn chairs within an inch of the edge of the highway pavement, or any manner of vehicle repair being performed ANYWHERE on the roadway 4) avoid sudden movements such as lane changes or rate of travel because other drivers will stop ahead of you at any moment for no apparent reason or approach from the rear or the side at shocking speeds. I wish them luck.

I have friends flying into the Capital on Sunday and they are renting a car and driving to Sosua. What can I tell them in truth about the roads?
