You can add an additional driver to your Hertz rental car, but it must be done at the rental counter before you drive away, and the added driver must be present with their valid driver's license and card. There is almost always an Additional Driver Fee charged per day, and the person you're adding must meet Hertz's age and license requirements. Spouses or domestic partners are often added for free at some corporate-owned locations, but this policy is not universal, so always confirm in advance.
The process is straightforward but requires planning. You cannot add a driver later through the app or over the phone once the rental agreement is active. Here’s a step-by-step breakdown:
The following table outlines key data points regarding Hertz's additional driver policy based on common U.S. practices (always verify with Hertz directly as policies can change).
| Policy Aspect | Details |
|---|---|
| Fee (Approximate) | $10 - $15 per day, per additional driver. |
| Spousal/Domestic Partner Waiver | Often waived at corporate locations; not guaranteed at franchisee-owned airports. |
| Minimum Age | Typically 25 years old; younger renters (21-24) may have restrictions. |
| License Requirement | Valid, non-probationary license held for at least 1 year. |
| Maximum Number of Drivers | Usually 3-4 additional drivers per rental contract. |
| When to Add | Only at the time of pickup, before taking the car. |
Failing to add a driver properly means they are not covered by the rental insurance, and driving the car could be a violation of your contract, potentially voiding all coverage.

Just went through this last week. You both have to go to the counter together with your licenses. They’ll run the other person’s card for a hold and charge a daily fee—it was $13 a day for us. The big thing is you can’t do it later via the app; it’s a counter-only thing. If your spouse is the added driver, ask if the fee is waived. Sometimes it is, but don’t count on it, especially at the airport.

My main advice is to factor the extra driver cost into your budget upfront. That daily fee adds up quickly on a long trip. Call the specific Hertz location you're using before you go to confirm their exact fee and if they offer any waivers. It’s a few minutes at the counter that saves huge headaches later. An unauthorized driver causing even a small fender bender could leave you financially responsible for all the damage.

I always handle the driving on family trips, but I add my wife as a driver just in case. The process is simple: we both go to the counter, show our licenses, and I pay the extra daily charge. It’s worth the peace of mind. If I get tired or unwell, she can take over without a worry. I make sure to check the contract before we leave to see her name printed right there next to mine. It makes the whole trip smoother.
