If two people may drive during your Miami rental, arrange that before the second person takes the wheel. Being a spouse, friend or colleague does not by itself establish permission under the rental agreement. Ask the team to confirm the additional-driver requirements for the specific car and booking.
The rental policies are a starting point; the final agreement should identify who is authorised. This guide helps organise the request without assuming one rule, age requirement or fee applies to every vehicle.
Decide who will drive before requesting a quote
Think about the full trip. One person may collect the car, another may prefer longer drives, and someone else may be expected to return it. Include every intended driver in the enquiry rather than adding names informally to a group chat after collection.
Ask which documents each person must provide, whether they must attend pickup, what eligibility checks apply and whether there is an additional charge. Send sensitive documents only through the channel the team specifies; a planning message need not include a full payment-card number.
| Item | Confirmation to keep |
|---|---|
| Each intended driver | Name recorded correctly in the agreement |
| Eligibility | Required documents and vehicle-specific conditions |
| Pickup attendance | Who must be present and when |
| Cost | Any additional-driver fee in the full quote |
| Return | Who is permitted to bring the car back |
| Mid-rental change | How to obtain approval before another person drives |
Treat approval and insurance as separate questions
Adding a name to the rental agreement does not answer every coverage question. If you rely on personal insurance or card benefits, ask the relevant provider whether the vehicle, rental period and intended drivers meet its terms. Do not infer coverage from a card logo or from a policy that covered a different trip.
The FTC's rental-car guidance notes that additional drivers may carry fees and that unauthorised driving can affect protection. Use that as a reason to resolve the details before pickup, not as a substitute for your actual agreement.
If plans change during the rental
Contact the team before handing over the keys. Provide the booking reference, proposed driver's name and the time from which the change is needed. Wait for the required approval and documentation. A message requesting permission is not the same as receiving it.
If the primary driver cannot continue, explain the situation and ask for an authorised solution. Do not improvise by assuming an emergency automatically changes the contract.
Keep one clear record
Save the final agreement and any approved amendment with your pickup and return details. Make sure both drivers understand mileage, fuel, parking, tolls and the contact process if something changes. Sharing a car works best when responsibility is clear rather than divided between several incomplete conversations.
For a longer stay, the weekly-versus-monthly guide covers a different decision: choosing the rental period. Include the additional-driver request in that same quote so the total reflects the way you will actually use the car.
