Additional Driver on a Car Rental: Rules, Fees and How to Do It Right
How to add an additional driver to a car rental: who must be listed, the documents needed, typical fees, insurance risks, and tips for couples and families.
Yes, anyone who gets behind the wheel of your rental car must be listed on the rental agreement as an additional driver, and adding one usually means presenting their licence and passport and, in many cases, paying a small daily fee. If an unlisted person drives and has an accident, the insurance and damage waiver can be voided, leaving you liable for the full cost of the car.
That single rule catches out more travellers than almost anything else at the rental counter. Below is a plain-spoken, honest guide to how additional drivers actually work in Europe and North Africa, what you can expect to pay, and how couples and families can share the driving without a nasty surprise.
- Every person who will drive must be named on the contract before they touch the wheel; an unlisted driver typically voids your insurance and damage cover.
- An additional driver needs a valid full driving licence, a passport or ID, and usually an International Driving Permit if their licence is non-EU or not in the Latin alphabet.
- Additional-driver fees are typically a small per-driver, per-day charge, sometimes capped, and are occasionally waived for a spouse or folded into inclusive rates.
- You can add a driver at booking or at pick-up, but doing it in advance is calmer, usually cheaper and avoids counter pressure.
- On a transparent marketplace like DRIVO you see what's covered and the deposit before you book, so additional-driver terms don't ambush you at the desk.
Why every driver must be listed
A rental agreement is a legal contract between you and the agency, and the insurance attached to it only covers the people named on it. The named renter is the person the agency has verified, whose licence they've checked, and whose card holds the security deposit. Anyone else is, from the insurer's point of view, an unauthorised driver.
This isn't fine-print pedantry. If an unlisted friend or partner is driving and something goes wrong — even a minor scrape — the agency can refuse the damage waiver entirely. Instead of paying an excess of a few hundred euros, you could be billed for the full repair or, in a write-off, the value of the car. Listing a second driver costs a little; not listing one can cost everything.
What documents an additional driver needs
The additional driver goes through nearly the same checks as the main renter. Bring these to pick-up:
- A valid full driving licence held for the minimum period the agency requires (commonly one to two years).
- A passport or national ID card that matches the name on the licence.
- An International Driving Permit (IDP) if the licence was issued outside the EU/EEA or isn't printed in the Latin alphabet — this is common for travellers renting in Morocco, Tunisia or across Europe on a non-European licence.
- Sometimes a second form of ID or proof of address, at the agency's discretion.
The additional driver must be physically present at pick-up so the agency can see the original documents and photocopy the licence. A photo on a phone is not enough. Age rules apply to them too: if the agency charges a young-driver surcharge under 25, or restricts drivers under 21, that applies to each named driver, not just the main renter.
Typical additional-driver fees — and when they may be waived
Most agencies charge a per-driver, per-day fee, though the exact amount varies by country, season and company. Traditional counters often quote it as an optional extra you only discover at the desk, which is exactly the kind of surprise a transparent listing should spare you. Here's roughly what to expect.
| Scenario | Typical additional-driver cost | Notes |
|---|---|---|
| Standard second driver | A modest per-driver, per-day fee | Often the single biggest surprise line at the counter |
| Fee capped per rental | Flat cap after a set number of days | Some agencies stop charging after, say, the first week |
| Spouse / civil partner | Sometimes free | Depends on the agency and the country; ask, don't assume |
| Inclusive or premium package | Included | One or more additional drivers bundled into the rate |
| Unlisted driver | Nothing upfront — but cover voided | You pay for any damage in full; never worth it |
When might the fee disappear? A spouse or civil partner is the most common waiver, though it's never guaranteed and often depends on showing proof of the same address. Loyalty schemes with the big chains sometimes drop the charge, and some all-in rates simply fold one additional driver into the price. The honest advice: treat the fee as payable unless the booking clearly states otherwise in writing.
Insurance implications if an unlisted person drives
This is the part worth reading twice. Standard rental insurance and the collision damage waiver are conditional on the driver being authorised. Let an unlisted person drive and, in the event of a claim, the agency and its insurer can treat it as a breach of contract.
- The damage waiver and theft protection can be cancelled, exposing you to the full value of the car.
- Any insurance the agency arranged for you may not apply at all, because the person driving wasn't a listed driver in the first place.
- In a serious incident, third-party liability disputes and legal costs can follow you home.
The fix is simple and cheap: name every potential driver up front. If you booked on a marketplace where you could see what the agency's own insurance covers before paying, you already know where you stand — and once every driver is properly listed on the contract, the agency's cover applies to all of them, not just one.
How to add a driver — at booking or at pick-up
At booking (recommended)
Adding the driver when you reserve is the calm, cheaper route. You enter their details in advance, the fee is shown before you commit, and there's no counter negotiation with a queue behind you. On a transparent platform you see the rental price and the service fee up front, the agency's own insurance terms, the security deposit, and what's covered — so an additional-driver term is visible rather than sprung on you.
At pick-up
You can almost always add a driver at the desk too, as long as they're present with their documents. The trade-off is that pick-up is exactly when up-sell pressure peaks, and any fee is charged on the spot. If plans change and a new person needs to drive mid-rental, call the agency first and add them properly before they take the wheel — never just hand over the keys.
Tips for couples and families sharing the driving
- List both partners from the start on a long road trip — swapping drivers legally beats one person doing every motorway hour.
- Ask specifically whether a spouse is exempt, and get the answer reflected in the price you pay, not just a verbal 'probably'.
- For families, remember additional-driver rules cover any adult who might drive — a grown child or a visiting relative included.
- Check the young-driver surcharge before assuming a 23-year-old can share the wheel for free.
- If you're renting in North Africa or on a non-EU licence, sort the International Driving Permit for every driver at home; you can't buy it at the counter.
- Book somewhere the total, the deposit and the inclusions are visible up front, so the second-driver line is a known number, not a pick-up surprise.
That last point is really the whole story. Additional-driver rules exist for good reasons — safety, verification, valid insurance — and they're easy to satisfy. The frustration almost always comes from opacity: fees and conditions that only appear once you're at the desk. DRIVO is built the other way around, letting you rent directly from trusted local agencies across Europe and North Africa with transparent pricing — the rental and DRIVO's service fee both shown up front — the deposit and what the agency's insurance covers shown before you book, instant confirmation, free cancellation up to 48 hours before pick-up, and concierge support over WhatsApp or in-app in five languages. Add your drivers, know your numbers, and drive.
Do I have to add my partner as an additional driver if we're sharing the car?
Yes. If your partner will drive at all, they must be named on the contract and present at pick-up with their licence and ID. Some agencies waive the fee for a spouse, but the listing itself is never optional.
How much does an additional driver usually cost?
Usually a modest per-driver, per-day fee, though it varies by country, season and agency and is sometimes capped per rental or bundled into inclusive rates. Always confirm the figure in writing before you book.
What happens if an unlisted person drives the rental car?
Your insurance and damage waiver can be voided, meaning you're liable for the full cost of any damage or the value of the car in an accident. It's never worth the risk — add every driver in advance.
Can I add an additional driver after I've picked up the car?
Usually yes, but call the agency and add them properly before they drive. The new driver must present their documents, and any fee applies from that point. Don't simply hand over the keys.
Does an additional driver need an International Driving Permit?
If their licence was issued outside the EU/EEA or isn't in the Latin alphabet, then usually yes — especially in Morocco, Tunisia and much of Europe. Arrange the IDP at home, as you can't obtain it at the rental counter.
Is there an age limit for additional drivers?
The same age rules apply to every named driver. Under-25 drivers may face a young-driver surcharge and under-21s may be restricted entirely, so check before assuming a younger traveller can share the driving.
