Rental-Car Additional Driver Rules and Fees
An additional driver should be authorized under the rental agreement before taking the wheel. Eligibility, daily fees and exemptions vary by company, pickup location, payment method, membership, corporate rate and local law. Being a spouse, having personal insurance or holding a valid license does not by itself…
Timeline
- 2023-09: The FTC published its current rental-car consumer guidance, including additional-driver fees and unauthorized-driver waiver risks.
- 2026-10-12: Current federal consumer guidance and rental-company policies were reviewed for this guide.
An additional driver is someone other than the primary renter who is permitted to operate the rental vehicle under the agreement. Authorization is the first question; price and insurance are separate questions. A person can hold a valid license and personal auto policy yet still violate the rental contract if the company has not authorized that driver. Before anyone else takes the wheel, read the signed agreement and confirm that the person is either named or expressly included by the applicable policy. [1][2][3]
The usual process is to add the driver at pickup, although some companies permit an amendment during the rental. Hertz says the renter and proposed additional driver generally must appear at a rental location, present valid licenses and sign the updated agreement. The additional driver must meet the company’s standard qualifications, including minimum age and any vehicle-class restrictions. Do not assume that entering a name during an online reservation completed the authorization; inspect the final contract issued at the counter. [2][4]
Fees vary by company, country, branch and rate plan. The FTC notes that some companies charge to add another driver. Hertz describes its standard charge as per day and per person, while its support page lists exceptions tied to loyalty status, family relationships, California rentals and qualifying corporate business. A young-driver or age-differential charge can apply on top of the additional-driver fee. Compare the full rental total rather than multiplying the advertised base rate alone. [1][2][4]
Spouse and family rules are especially easy to misread. A spouse or domestic partner may be included under a particular membership, jurisdiction or contract, but that does not create a worldwide automatic exemption. Enterprise’s San Francisco airport policy, for example, authorizes several relatives and coworkers without an extra charge when they meet the same age and license rules, yet limits a debit-card rental to a spouse or domestic partner as the only additional driver. The pickup location’s written terms control the specific rental. [2][3]
Authorization also affects damage responsibility. FTC guidance says a rental company’s collision or loss damage waiver may be canceled if an unauthorized person drives. Personal auto insurance, employer insurance and credit-card rental protection have their own definitions, exclusions and payment conditions; a rental company cannot determine whether an outside policy is adequate. Ask each provider whether the primary cardholder must rent and drive, whether named additional drivers are covered and whether travel outside the permitted area changes protection. [1][3]
Every authorized driver remains bound by the rest of the contract. Geographic and border limits, prohibited uses, toll rules, fuel terms and reporting duties do not disappear when a second driver is added. Enterprise’s SFO policy illustrates this by excluding some specialty vehicles from Canada and prohibiting its U.S. rentals from entering Mexico. Confirm the actual vehicle class and itinerary, especially for a one-way trip, international border crossing, large van or corporate booking. [3]
If plans change after pickup, contact the renting branch before swapping drivers. Ask whether both people must return in person, what identification or payment card is required, when the charge starts and whether the amended agreement will be emailed. Keep the written revision in the car or available offline. In an accident, follow the agreement’s reporting instructions and identify the actual driver accurately; trying to recast an unlisted driver after the event can compound a coverage and contract dispute. [1][2][4]
A useful checkout sequence is to identify every intended driver, verify license and age eligibility, request all exemptions or negotiated rates, and review the itemized total. Then confirm that each name or authorized category appears in the executed agreement and separately verify damage waiver, liability, personal-policy and card benefits. Photograph or download the final contract. If the document and the agent’s explanation conflict, resolve the discrepancy in writing before leaving the lot or letting the other person drive.
