I was warned by a local several months ago to avoid the Villa Altagracia-San Cristobal road because of the robberies that were taking place on that road, even during the day. It is a nice stretch of road but the warnings said several people, Dominicans, had been treated violently when they resisted. It happened after a rain storm when the road was partially flooded and cars slowed down to navigate the water in the road. A few well placed boards and it is easy to cause a flood on the road. I have stayed off that road since.
