If you're 18 or elder you're considered mature enough to pay taxes and even vote. But there’s no car rental company offering car rental under 18 La Romana, Dominican Republic.
Sorry, but this is a common age policy of car rental companies all over the world, and you have to accept it.
Car rental under 18 La Romana, Dominican Republic users are not eligible to sign a contract and if the renter decided not to pay, it would bring a huge risk to the car rental company.
