Quick Summary:
- Adding a driver can trigger extra fees that increase the card authorisation.
- Insurance only applies when every driver is named on the contract.
- Ask staff to reprint the agreement showing all drivers and charges.
- Check credit card limits before pick-up, especially for SUVs in Las Vegas.
When you collect a car hire vehicle in Las Vegas, it is tempting to treat “extra driver” as a small admin tweak. In practice, adding another driver can affect two things you care about immediately at the counter, the deposit (usually taken as a pre-authorisation on your card) and whether the insurance or damage cover you have is valid while the other person is driving.
The key is that most rental systems treat the additional driver as a contract change. Contract changes can add daily fees, change the risk profile, and require fresh verification checks. That is why you should expect the authorisation amount to be recalculated and why you must ensure every intended driver appears on the rental agreement before you leave the lot.
If you are arranging car hire around the airport, policies can differ by supplier and package, but the principles stay consistent. The practical details below will help you understand what can change, what should not, and what to check at pick-up so you do not get a surprise decline on your card or an uncovered incident later.
What “deposit” really means at Las Vegas pick-up
At Las Vegas car hire pick-up, “deposit” typically means a temporary authorisation, not money taken permanently. The rental company places a hold on the main driver’s credit card to cover potential costs such as the excess, fuel, toll admin fees, late return charges, or unpaid extras. The funds remain unavailable until the hold is released after the car is returned and the final bill is settled.
The authorisation amount is usually made up of two parts, the security amount tied to the vehicle and cover, plus an estimated amount for the rental charges. If you add optional items or services at the counter, the estimated rental charges increase, and the authorisation often increases with it.
For travellers collecting at the airport, it helps to read the pick-up guidance specific to the location you are using, as airport concessions can influence taxes and local fees. See Las Vegas airport car rental for location context and planning tips.
Can adding an extra driver increase the authorisation amount?
Yes, it can, and there are three common reasons.
1) Additional driver fees raise the estimated total. Many suppliers charge a daily fee per additional driver, sometimes capped at a maximum. When that fee is added, the estimated rental total rises, and the authorisation can rise accordingly. Even if the “security” portion stays the same, the overall hold may still be higher.
2) A different driver can trigger extra verification or eligibility checks. If the extra driver is under a certain age, newly licensed, or has a licence from a jurisdiction requiring additional documentation, the rental desk may apply a young driver surcharge or require additional checks. Surcharges are still charges, and that can increase the authorisation.
3) Vehicle category and risk profile can affect the hold. Higher-value vehicles can carry higher pre-authorisations. If you are hiring a larger vehicle for a group trip, the baseline authorisation may already be higher, and any added fee makes the hold more likely to push your card limit. If you are comparing categories, you can review Las Vegas options such as SUV hire in Las Vegas to understand how category choices may interact with counter requirements.
Important nuance, some suppliers keep the security hold fixed and only add the extra driver fee to your final bill. Others recalculate the full authorisation based on a fresh estimate. Either way, plan for the possibility of an increased hold when the contract is modified.
Will it change the insurance or damage cover?
It can, depending on what cover you have and what the supplier requires for it to apply.
Contract-listed drivers are the foundation of cover. Whether you have a package that includes a damage waiver, theft protection, or additional cover products, they generally apply only when the vehicle is driven by an authorised driver. An authorised driver is typically the main driver and any additional drivers who are explicitly listed on the rental agreement.
If the second person drives without being listed, you risk invalid cover. That can mean the driver is treated as unauthorised, and the supplier may pursue the full cost of damage, plus administrative fees, even if you thought you had “insurance”. This is one of the most costly misunderstandings in car hire.
Adding a driver is not the same as “being insured to drive at home”. Your personal motor insurance at home rarely extends to a US rental, and even when it does, it may not cover all drivers unless named. Similarly, card benefits can have strict conditions. The rental contract still needs to list the driver for the supplier’s cover conditions to be met.

When the deposit should not change, and why it still sometimes does
There are situations where adding an extra driver does not necessarily change the authorisation amount. For example, if your rate already includes an additional driver at no extra cost, or if the supplier waives the fee for a spouse or domestic partner under certain conditions. In those cases, the estimated charges might not rise.
However, even when the cost is waived, the desk may still need to re-run the authorisation because the contract has been reissued. That reissue can temporarily create two holds, an old one that will later drop off, and a new one reflecting the updated contract. This can look like the deposit “doubled” on your banking app for a short time, even though it should resolve when the first authorisation is released.
If you are close to your card limit, that temporary overlap can cause a decline. The best prevention is to ensure your card has sufficient headroom for a reauthorisation and to keep an eye on notifications from your bank during pick-up.
What must be listed on the contract before you drive away
To protect both your budget and your cover, treat the rental agreement as the single source of truth. Before you leave the pick-up area, confirm the following are printed on the contract and match what you requested:
All drivers’ full names. The additional driver must be explicitly named. Do not rely on a verbal confirmation. If there is a separate sheet for additional drivers, keep it with the main agreement.
Driver licence details where shown. Some agreements reference licence issuing state or country. If the licence information is wrong, ask for correction.
Any additional driver fees and their rate basis. Look for per-day charges and any caps. If it was meant to be included, ensure it shows as included or zero.
Selected cover and exclusions. If you purchased cover at the desk or your package includes it, the agreement should reflect the relevant products. If you declined cover, ensure you understand what liability you are accepting.
The authorisation amount or deposit reference. Not every agreement prints the hold amount, but you can ask the agent to confirm it and show how it was calculated. If you are unsure, request a breakdown, vehicle, rental charges estimate, extras, and any local fees.
Fuel policy and return instructions. Extra driver changes can distract you, but fuel charges are one of the most common surprises. Make sure the fuel option matches what you agreed.
This is also the right moment to confirm where to return the car and how tolls are handled, because toll programmes can add daily fees even if you do not use toll roads.
How to add an extra driver smoothly at Las Vegas pick-up
If you know you will want a second driver, the easiest path is to plan for it and bring the right documentation. The additional driver should be present at pick-up with their physical driving licence and a passport or ID if required by the supplier. Some desks will not add a driver who is not physically there to sign.
Ask the agent to add the driver first, then confirm the updated price and authorisation before you insert your card. This reduces the chance of multiple authorisations. If you are already checked in and then remember the extra driver, expect a reissue and possibly a new hold.
Supplier rules can vary. If you want to understand the way large brands often structure add-ons and contract changes, you can review pages such as Alamo car rental in Nevada and Payless car rental in Nevada. Even within one brand, the exact fees and waiver rules can depend on the counter location and your chosen package.
Common scenarios that change deposit or cover
Scenario A, adding a driver who is under 25. In the US, under-25 surcharges are common. If the additional driver triggers one, the rental total rises and your authorisation may rise. Cover is only valid for that driver if they are accepted and listed on the agreement.
Scenario B, you have cover but forget to list the second driver. This is the classic “insurance surprise”. The cover might apply to the vehicle and the agreement, not to any person who happens to be behind the wheel. The fix is simple, add the driver properly, but do it before driving off.
Scenario C, the counter reissues the contract and you see two holds. This can happen when a contract is amended. If your bank app shows two authorisations, ask the agent which one is active and when the previous one should drop. Your bank controls the timing, but the desk can usually confirm that the old one is voided.
Scenario D, you change vehicle category and add a driver. Upgrading to a larger car and adding an extra driver at the same time stacks two changes, higher rental charges plus extra fees, making a higher authorisation more likely. If budget is tight, do one change at a time and confirm the new total before proceeding.
Practical checklist before you leave the lot
Check the agreement header. Confirm location, date, time, and the primary driver details.
Confirm the driver list. The additional driver must be printed as an authorised driver, not just noted verbally.
Reconfirm the charges. Look for additional driver fee lines, young driver fees, and any cover product lines you accepted.
Confirm the authorisation amount. Ask for the amount the card was authorised for and keep the receipt.
Keep all paperwork accessible. If you are stopped or need roadside help, having the agreement showing all drivers reduces delays.
Doing these checks takes a couple of minutes, but it can prevent a bigger financial headache, especially in Las Vegas where road trips often start immediately after pick-up.
FAQ
Does adding an extra driver always increase the deposit in Las Vegas? Not always. If the additional driver is free in your rate, the hold may stay similar, but the desk might still reauthorise the card after reissuing the contract.
If the extra driver is not on the agreement, are we still covered? Usually not. Most cover and waivers apply only when an authorised, contract-listed driver is driving, so ensure every driver is printed on the agreement.
Can I add the extra driver later, after leaving the airport? Often yes, but you may need to return to a rental counter or approved location with the driver’s licence. Until they are added, they should not drive.
Will the additional driver need to be present at pick-up? Many suppliers require the additional driver to be present with their physical driving licence to be added and to sign, although rules can vary.
Why do I sometimes see two deposits after changing the contract? A contract amendment can create a new authorisation while the previous one is still pending release. The earlier hold should drop off once voided and processed by your bank.
