A Guide to Additional Drivers for Car Rentals: Your Ticket to Stress-Free Travel

Adding an extra driver to your car rental agreement might not sound like the most exciting part of planning your trip, but it’s one of the most thoughtful decisions you can make.

Let’s examine why this simple step should be on your pre-trip checklist and how it enhances your entire travel experience.

Why You Need an Additional Driver?

Adding a secondary driver to your car rental agreement offers several key benefits that enhance convenience, safety, and flexibility during your trip.

Firstly, it allows for shared driving responsibilities, which is beneficial on long journeys or road trips. Sharing the wheel helps reduce fatigue and ensures that everyone stays fresh and alert behind the wheel.

Another significant advantage is increased flexibility and preparedness. If one driver becomes unavailable due to illness, exhaustion, or other unforeseen circumstances, having a backup ensures the trip continues smoothly without interruptions

Adding extra drivers ensures compliance with rental policies and insurance coverage. Rental companies require all drivers to be listed in the agreement to avoid voiding the insurance.

If someone drives without being officially added, you risk losing coverage in case of accidents or damages. For instance, if your friend takes the wheel briefly while you rest but isn’t listed as an authorized driver, any incident could leave you liable for costs.

Finally, sharing driving duties fosters a sense of teamwork among travelers. Whether you're traveling with family, friends, or colleagues, taking turns driving lets everyone relax and enjoy the scenery rather than focusing solely on navigating unfamiliar roads.

Who Can Be an Additional Driver?

Not just anyone can hop into the driver’s seat, though. Most rental agencies require additional drivers to present a valid driver’s license and meet age requirements (typically 21 or older). Some places even mandate that all drivers appear at the rental office to sign paperwork in person. This process ensures everyone is vetted and meets the company’s standards.

Spouses or employees traveling under a corporate contract often get special treatment, sometimes avoiding fees altogether. However, friends or family members will likely incur a small charge, usually around $10−15 per day per driver.

International travelers may need to provide an International Driving Permit (IDP) alongside their home country’s license. Always double-check the rules before arriving at the rental counter.

How to Add a Secondary Driver to my Car Rental Agreement?

Adding an additional driver to your rental agreement is a simple process but must be done correctly to ensure insurance coverage and avoid penalties. Here’s how it works:

Visit the rental counter: At the time of pick-up, inform the rental agent that you'd like to add another driver. Car rentals allow you to add a driver online during the booking, but in most cases, both you and the additional driver must be physically present.

Provide necessary documents: The additional driver must show a valid driver’s license and, in some cases, a passport or another form of ID. If you're renting abroad, they may also need an International Driving Permit (IDP) depending on the local laws.

Meet age and experience requirements: Most companies require additional drivers to be at least 21–25 years old with at least 1–2 years of driving experience. If these conditions aren’t met, the driver might not be approved or may face a surcharge.

Sign the agreement: The additional driver will typically need to sign the rental agreement, confirming they are authorized to drive the vehicle.

Pay any applicable fee: Many rentals charge a daily fee for each additional driver. This can vary depending on the country, vehicle type, and rental duration.

Book Smart: Some loyalty programs or membership clubs offer free additional drivers as part of their perks. Certain credit cards or travel memberships waive these fees entirely.

Travel During Off-Peak Seasons: Car rentals often lower their rates during quieter months, including those pesky add-on charges.

Negotiate On-Site: Believe it or not, you can sometimes haggle with rental staff. Politely ask if they can reduce or waive the fee.

Always confirm the total cost upfront. Fees vary wildly depending on location, so don’t assume what applies in one country will hold elsewhere.

Additional Drivers for Car Rentals: FAQs

What documents are required to add extra driver to a rental car agreement?

Car rentals require three key documents to add an additional driver: a valid driver’s license from the driver’s home country, a passport or national ID for identity verification, and a signed rental agreement. Sometimes, international drivers may also need to provide an International Driving Permit (IDP). For example, if you're renting a car in Canada for a road trip and your companion is from the US, their local license must be paired with an IDP to be accepted.

Is the additional driver equally liable in case of damage or a traffic violation?

While the primary and additional drivers are authorized to use the vehicle, the primary driver typically holds legal and financial responsibility. This includes paying for damages, fines, or breach of terms. However, if the additional driver causes an accident, the rental company may hold them liable under civil law, depending on local regulations.

How does adding an additional driver affect insurance coverage?

Adding an additional driver can expand insurance coverage to include them as long as they’re officially registered in the rental agreement. However, coverage terms might differ based on age, license type, or driving history. For example, if your travel partner is under 25 and added as a driver, the insurance might include them, but with higher deductibles or limited vehicle class coverage. Always confirm the policy limits and exclusions for each listed driver to avoid surprises.

Are there age restrictions for adding additional drivers internationally?

Age restrictions are often more complex when renting internationally. While some countries allow drivers aged 21–24 to be added with a young driver surcharge, others may set the minimum at 25. For instance, in particular Gulf countries, only drivers aged 25 and above with a clean driving record are allowed to be additional drivers without extra paperwork. Always check both the rental agency’s rules and local laws to ensure compliance.

Can I add an additional driver at any point during the rental period?

In most cases, yes—you can add a driver after the rental has started. However, both the primary and additional drivers must visit a rental location in person. The new driver must show their license and sign the agreement. For instance, if you're on a week-long road trip through Portugal and decide mid-trip to share driving with a friend, you'll need to stop by a branch with them to authorize the change legally.

Will the cost of adding an additional driver change based on car type or rental duration?

The cost can vary depending on the vehicle type and the rental length. Larger or luxury vehicles may incur higher driver fees due to increased risk, and longer rentals might incur cumulative daily fees. For example, adding a second driver for a compact car on a 2-day rental might cost less than a premium SUV over 10 days. Some companies also cap the fee after a certain days, so ask for a breakdown before booking.

Do additional drivers need to meet the exact driving experience requirements?

Additional drivers must meet the same standards as the primary renter. That includes minimum driving experience, often at least one to two years, depending on the region. In some countries, rental companies may refuse to authorize a driver who got their license within the last 12 months, even if they meet the age requirement. Always check the fine print for experience thresholds to avoid disqualification.

What happens if someone drives the car without being added as an additional driver?

Insurance coverage can be completely voided if an unauthorized person drives the car and gets into an accident. That means the renter becomes fully responsible for all repair costs, third-party liability, and legal repercussions. Even a minor scratch could lead to hefty bills. For example, if you're traveling and let a friend not listed on the agreement drive “just for a bit,” the insurer could deny all coverage, regardless of fault.

How does the rental agreement reflect the rights of additional drivers?

The rental agreement legally defines who is allowed to drive the car. The additional driver's name, license number, and signature must be listed. However, only the primary driver is contractually responsible for the rental, including payment, extensions, and communication with the agency. For instance, if the car is towed or impounded, only the primary renter can retrieve it, even if the additional driver used it at the time of the incident.

Are there any special considerations for adding an additional driver in certain countries?

Absolutely. Requirements can vary drastically by country. In the UAE car rentals, for example, a foreign additional driver may need an International Driving Permit and a visa stamp showing their entry. In the UK, drivers with licenses from outside the EU might need extra paperwork, and driving on the left side could affect insurance assessments. Research your destination's local driving rules and rental regulations before listing another driver.

Wrapping Up: Drive Smarter, Not Harder

At the end of the day, renting a car is about freedom to explore new places, chase spontaneous detours, and create unforgettable moments. And adding an extra driver amplifies that freedom tenfold.
