Executive Summary

Sharing the driving can turn a long journey into a smoother, safer, and more enjoyable experience. One person can handle the highway while the other relaxes, manages directions, checks the itinerary, or takes over when fatigue begins to build with Zoom Rentals.

Yet the additional driver car rental process remains one of the most misunderstood parts of renting a vehicle. Many travelers assume that a spouse, partner, friend, or family member can drive automatically. In reality, every person who operates the rental should be properly authorized under the rental agreement.

This guide explains how to add a driver to a rental car, what documents are required, how much a car rental extra driver may cost, and why arranging it correctly protects your trip.

What Is an Additional Driver?

An additional driver is a second person who is legally authorized to operate the rental vehicle. They are not simply a passenger with permission from the primary renter. Their name must be added to the rental contract as an additional authorized driver.

Once approved, the second driver can take the wheel under the rental company’s terms. They must follow the same rules regarding licensing, age, driving area, vehicle use, insurance, and return conditions.

If someone drives without being listed, the rental agreement may be breached. Coverage and liability can also become more complicated if an accident, traffic violation, theft, or damage occurs. The safest approach is straightforward: add every person who may drive before handing over the keys.

Why Adding a Driver Is Worth It

The FTC publishes consumer guidance on renting a car, including practical information about rental fees and driver requirements that travelers should understand before authorizing another person to drive.

Share long distance driving

Road trips across Ontario, Alberta, the United States, or the Caribbean can involve several hours behind the wheel. A second driver allows the journey to be divided into manageable stretches instead of leaving one person responsible for the entire route.

This is especially useful when traveling from Toronto Airport to destinations across Ontario, driving between major cities, or planning a multi-stop vacation.

Reduce fatigue

Driver fatigue affects concentration, reaction time, and decision-making. Taking regular turns helps both drivers remain alert and comfortable. A second driver is not a substitute for proper rest, but it creates more flexibility when the itinerary includes early departures, late arrivals, or long highway sections.

Handle errands and changing plans

An additional driver gives your group more freedom when the primary renter is unavailable. One person can collect luggage, manage hotel check-in, attend a meeting, or deal with an unexpected task while the other drives.

Create more flexibility for families

Families often benefit from a second driver when children need attention, the itinerary changes, or one parent needs a break. Groups traveling in a spacious standard SUV rental for family road trips or a 12-passenger van rental for group travel can coordinate the journey more comfortably when more than one qualified adult is authorized to drive.

Who Can Be Added as an Additional Driver?

A spouse, domestic partner, family member, friend, colleague, or travel companion may generally be added if they meet the rental location’s requirements. As an example of common industry standards, Enterprise’s official additional-driver FAQ outlines similar eligibility and authorization expectations.

The additional driver typically needs:

• A valid physical driver’s license

• The required minimum driving age

• Government-issued identification when requested

• A passport for many international renters

• Any required license class or insurance documentation

• Approval under the rental company’s driving policies

Age requirements vary by location and vehicle category. Zoom’s published FAQ shows that standard vehicle requirements can differ between branches. Some locations permit renters from age 21, while others use age 23 for standard vehicles. Drivers below the standard age threshold may also face an underage surcharge.

Luxury vehicles and larger specialty vehicles can have higher minimum-age requirements. Confirm the rules for your pickup location and vehicle class before adding the driver.

How to Add a Driver to a Rental Car

Adding a driver is usually simple when completed before the vehicle leaves the rental location.

1. Identify the driver before booking

Decide who may drive during the trip. Include anyone who could realistically take the wheel, even if you expect the primary renter to do most of the driving.

Adding the driver at the beginning avoids last-minute changes at the counter and ensures the rental agreement reflects your actual travel plans.

2. Select your vehicle and location

Use the Zoom Rentals homepage to select the pickup location, rental dates, driver age, and vehicle category. Review the vehicle options before deciding whether an economy car, SUV, minivan, or passenger van best suits your group.

Zoom serves travelers across Canada, the United States, and the Caribbean through a growing network of airport and city locations. You can review the full service area on the locations page.

3. Ask to add the driver during booking or pickup

If the online reservation does not display an additional-driver option, request the change when collecting the vehicle at one of Zoom’s locations. Tell the rental representative that another person will drive and needs to be listed on the contract.

The additional driver will generally need to be present so their documents can be reviewed and the rental agreement can be updated.

4. Present the required documents

The additional driver should bring their physical license and any other documents required for the specific location. Digital-only license copies may not be accepted.

International renters may need a passport and, depending on the license language and local requirements, an International Driving Permit. The primary renter must also satisfy Zoom’s payment and deposit requirements.

5. Review the revised agreement

Before leaving, confirm that:

• The additional driver’s name is correctly listed

• The fee is clearly shown

• The authorized driving area is understood

• Insurance or loss-damage options apply as expected

• Any age-related surcharge is included

• The return and mileage terms remain clear

• Any booking conditions align with Zoom’s Price Match Guarantee terms when relevant

Keep a copy of the updated rental agreement in the vehicle or in an accessible digital format.

What Is the Additional Driver Fee?

Zoom’s published rental policies state that up to two additional drivers may be added at an additional charge of $10 per day for each driver. This makes the potential car rental extra driver cost:

• One additional driver: $10 per day

• Two additional drivers: $20 per day

Taxes, location rules, vehicle category, age surcharges, and other rental terms may affect the final amount. The additional driver fee can also vary by branch, rental agreement, and applicable local regulations, and the FTC’s renting-a-car fee guidance is a useful consumer reference when comparing how companies present those charges.

Some rental companies waive the fee for a spouse or domestic partner, certain business rentals, loyalty members, or qualifying memberships. A waiver should never be assumed. Ask the rental representative to confirm whether the driver is free and ensure the agreement shows the correct charge or waiver. For another consumer-protection perspective on extra charges, the Georgia Attorney General’s Consumer Education page on rental car extra fees explains why these fees can appear in rental agreements.

For customers focused on value, Zoom also offers discounted car rentals to help reduce overall rental costs and extra fees, plus a Price Match Guarantee, subject to the terms of each program. Customers comparing total charges can also review Zoom’s pricing and fees where applicable.

Important Things to Know Before Adding a Driver

Authorization affects responsibility

The additional driver must be officially listed before driving. A verbal agreement between the primary renter and a friend does not replace written authorization from the rental company.

Insurance terms can vary

Adding a driver does not automatically make every insurance arrangement identical. Ask how the additional driver is treated under the selected loss-damage waiver, liability protection, personal auto policy, or credit-card coverage. Avis’s official additional-driver FAQ is also a useful reference for understanding how major rental brands address named additional drivers.

Coverage can depend on the driver’s age, license type, residence, vehicle category, and driving location. Review your protection options before pickup instead of waiting until an incident occurs.

Check geographic restrictions

Zoom policies may require approval and additional charges for travel outside the pickup province or state, across international borders, or into restricted areas. Every authorized driver must follow the same geographic limitations.

Use the right vehicle for the group

The best second driver rental car is one that matches the number of passengers, luggage, and driving conditions. A compact vehicle may suit a city trip, while a standard SUV provides additional space for family travel. Larger groups should review Zoom’s full fleet before booking.

Remove a driver when circumstances change

If an authorized driver will no longer operate the vehicle, contact the rental location and ask whether the agreement should be amended. Removing a driver can clarify who is permitted to drive and may prevent unnecessary charges on an extended rental. For broader policy details, review Zoom’s FAQ.

Frequently Asked Questions

1. Can I add an additional driver after picking up the rental car?

   You may be able to add a driver after the rental has started, but you must contact or visit the rental location first. The additional driver will need to meet the location’s age and licensing requirements and may need to sign an updated agreement. Do not let the person drive before the change is formally approved. You can also review general policy guidance on the Zoom Rentals FAQ page.

2. How many additional drivers can I add with Zoom Rentals?

   Zoom’s published rental policy permits up to two additional drivers. Each additional driver is listed at a charge of $10 per day, subject to location-specific terms, taxes, and applicable conditions.

3. How much is the additional driver fee at Zoom Rentals?

   The stated fee is $10 per day for each additional driver. One driver would add $10 per day, while two drivers would add $20 per day before applicable taxes or other charges.

4. Does the additional driver need to be present at pickup?

   An additional driver may be permitted to drive if they meet the location’s minimum age and license requirements. Drivers under the standard age may incur an underage surcharge, and some vehicle categories may not be available to them.

6. Is an additional driver covered by rental insurance?

   Coverage depends on the rental agreement and the protection selected. Ask whether the additional driver is covered under the loss-damage waiver, liability protection, personal insurance, or credit-card benefits. A driver who is not listed may create serious coverage concerns.

7. Can a friend be a second driver on a rental car?

   Some reservations allow additional-driver requests during booking, while others finalize the process at pickup. If the option is not visible online, contact the selected Zoom location or request the change at the rental counter.
