Yes, you can typically add an additional driver to a rental car agreement after you've already picked up the vehicle. However, it's not an automatic process and involves specific steps, potential fees, and adherence to the rental company's policies. The easiest and most recommended method is to handle it directly through the rental company's official channels.
The primary requirement is that the additional driver must present themselves in person at the rental location with their valid driver's license and a credit card in their name. The rental agent will then run the same eligibility checks they performed on you, including verifying the license and checking the driving record. This is a standard security procedure for all major rental companies. Expect to pay an additional driver fee, which is usually a daily charge. This fee varies significantly between companies and can be a deciding factor.
It's crucial to understand the insurance implications. The added driver will be covered under the same insurance policy you selected at pickup, but you must confirm this with the agent. Never allow an unauthorized person to drive the rental car, as this voids the rental agreement and all insurance coverage, leaving you fully liable for any damage.
The table below compares the additional driver policies for some major US rental companies. Note that spouses or domestic partners are often exempt from extra fees, but proof of relationship may be required.
| Rental Company | Can Add Driver Later? | Typical Daily Fee (for non-exempt drivers) | Spouse/Domestic Partner Fee Exemption? | In-Person Requirement? |
|---|
| Enterprise Holdings | Yes | ~$10 - $15 per day | Yes, at most US locations | Yes, with license & credit card |
| Hertz | Yes | ~$13 - $15 per day | Yes, with proof of address | Yes, with license & credit card |
| Avis Budget Group | Yes | ~$10 - $15 per day | Varies by location and brand | Yes, with license & credit card |
| Sixt | Yes | ~$15 per day | Case-by-case basis | Yes, with license & credit card |
The most important takeaway is to always contact the rental location directly as soon as you know you need to add a driver. Policies can differ by state, country, and even individual franchise locations. Proactively handling this is the only way to ensure you are fully compliant and protected.
