Your car insurance will not be accepted in Jamaica, we tried that the first year we rented got a additional rider to cover Jamaica but the rental car company would not accept it . We use a American Express CC, and /or a TD Visa travel rewards card, they both cover the insurance, I think some one mentioned a World Master Card for US folks works too. I have a Chase Saphire Visa I kept from when I lived in the States and they cover Jamaica too.
