What do you need to rent a car in San Martin?
Before you can take the wheel in San Martin, you’ll need a valid driver’s license and a credit card that matches the name on your license. If you choose not to take out the rental company’s insurance policy, you may also have to provide proof of alternative coverage. Requirements may vary, so understand the policy terms and conditions before you select a rental supplier.
Can I drive in San Martin with my U.S. Driver's license?
Yes, but if you really want to play it safe, obtain an International Driving Permit to accompany your U.S. License. The permit features your name, photo and driver’s details and is an useful additional identity document.
Can I rent a car for a month or longer in San Martin?
Yes, so you won’t need to rebook a rental car mid-vacation. Head to our long-term car rental deals page, enter your information and reserve a ride that’s all yours for however long you need.
Where can I find a San Martin car rental if I am younger than 25?
You’ll need to investigate the age policy of the San Martin rental providers you’re interested in. If you’re under the age of 25, be aware that some will charge additional fees. It’s better to know this before arriving at the desk so you can plan your budget accordingly. Every rental car company has its own policies for young drivers, so it pays to do your research.
