If you're planning a road trip in the United States and want to rent a car, you can typically add another driver to your contract. However, it might cost you a significant amount more depending on the company you choose. 

Although including additional drivers on a rental contract used to be limited to spouses and domestic partners, many rental car companies like Alamo, Avis, and Hertz now allow any licensed driver to be added to the contract for a fee. Some won't charge for spouses or partners and some won't charge for 

However, keep in mind fees and restrictions vary by location—from state to state and from city to city, even within the same rental company. Be sure to check with your preferred car rental agency for specific pricing details—and to see if you can avoid paying for an additional driver altogether while remaining insured on your road trip.

The situation is a little more complicated today. Some rental car companies allow renters to add spouses and domestic partners to their contracts free of charge. Others charge for domestic partners but not spouses or companion drivers. A few rental car companies charge to add even spouses as additional authorized drivers—except in certain states.

How to Add an Additional Driver for Your Rental Car

Saving Money on Adding Extra Drivers

The best way to avoid paying for additional authorized drivers is to do your homework early, well before you go to pick up your rental car. You can get information from the rental car company's website or call a customer service representative, but the answers you receive may not be accurate for your rental location.

The best way to know what you will be charged is to read your rental car contract carefully before you sign it. Because rental car company policies vary from state to state and even from office to office, be sure to review the entire contract.

Another way to avoid paying an additional driver fee is to join your car rental company's loyalty program. This strategy will not work in all cases, but it will help you avoid additional driver fees if you rent from National or Hertz.

Costco Travel members who rent from Avis, Budget, Alamo, or Enterprise will not be charged a fee for the first additional driver added to their contract.
