I would definitely want Exceso Civil added, I always go up to the maximum RD$ 15 Million. Little story about this. I met a lady who was from Europe, working in Punta Cana. She was driving on the highway one night back from work, a young guy comes straight across in front of her on a motorbike. She has no chance to stop, kills him. He was drunk, the bike was old and in a really bad state, no lights. But his family were well known and popular in Veron, not rich but well known and popular.
She was arrested at the scene (this is normal) but released a few hours later pending the investigation. She was advised she would not be allowed to leave the country until everything was settled (again normal). The case went to court, the insurance company paid out their RD$ 1M (even though everyone kind of knew it wasn't her fault, we all know how Dominican courts work). The family, the girlfriend, the aunty, all start holding their hands out, everyone is on the young boy's side, the case goes on and on. Eventually it took years to settle, and the lady ended up paying a huge amount (I think somewhere like US$ 30,000) to make it go away. During this time her mother got cancer and she was not allowed to leave the country.
This happened years ago but I seem to remember us discussing it on here, maybe it will ring a bell with some of the older members of the forum. And that's why I would recommend always maxing out your third party liability. If the insurance company is on the hook for RD$ 1M, they may well just pay and go. If it's RD$ 15M, that's a lot of cheese and they will try a bit harder to make things go away. And personally I prefer to have someone else drive and use Uber in the city rather than having a car. It's just a lot easier if things go wrong.
