Frequently asked questions

How old do you have to be to rent a car in Carmarthenshire?
You have to be at least 21. But there are a handful of age-related restrictions to bear in mind before locking in your Carmarthenshire wheels. If you’re a younger driver, rental providers will likely charge an extra fee and limit the sorts of vehicles you can rent. This size of the surcharge, and which age range it applies to, differs between companies. It’s always a good idea to compare the rules.
What do you need to rent a car in Carmarthenshire?
Any rental company you choose will require two things — a current driver’s license and credit card. If you’d like to opt out of the provider’s insurance plan, proof of your own coverage will also likely be needed. Check your policy so you know what to bring when it’s time to pick up your ride.
Can I drive in Carmarthenshire with my U.S. Driver's license?
Yes, your U.S. License is all you need to legally drive in Carmarthenshire. But if you’re the kind of adventurer who likes to dot your i’s and cross your t’s, get yourself an International Driving Permit. Apply for this document a few weeks before you take off.
Can I rent a car for a month or longer in Carmarthenshire?
Check out our long-term car rental deals page, enter your trip details and then secure a ride that suits. Whether you’re basing yourself in Carmarthenshire or plan to journey beyond, Expedia will help you find a long-term rental at an incredible rate.
Where can I find a Carmarthenshire car rental if I am younger than 25?
This depends on the rental car companies located in Carmarthenshire. They often have different age policies. If you’ve found a supplier that does cater to drivers under the age of 25 bear in mind that extra costs may apply. Conduct some research into what those charges could be before picking up the keys to your vehicle.
