Car rental services are on the rise in the United States, with the overall industry being worth over $60bn in 2025. The car-sharing movement has transformed how Americans drive, too, with millions now opting for the convenience and flexibility of borrowing vehicles on demand. People love how easy and stress-free car rental can be. Simply pick a vehicle, sign, drive, and enjoy the freedom that comes with your own wheels without the long-term commitment.

But even with all this convenience, some travelers still fall into common traps that can make their experience less smooth than it could be. To help you make the most of every trip, this article highlights the most frequent car-sharing mistakes — and how to steer clear of them.

Booking at the last minute

Many renters wait until a few days before a trip to reserve a car. In plenty of cases that’s not a problem, but when supply is tight last-minuters might find higher rates and limited choice. If you’re planning to rent a car over popular dates like holiday weeks, large events, spring break, and summer weekends, it’s a good idea to book at least a couple of weeks ahead of time. Remember also that carshare and rental locations close to airports tend to run out first, so be extra-organized if you want to pick up a vehicle at or near the airport.

For example, on Turo, booking in advance gives you a wider selection of vehicles and hosts, including premium or specialty models that tend to go first.

Ignoring the total price

Travelers often look at the base rental rate and miss the full cost that appears at checkout. Airport concessions, state and local taxes, energy recovery fees, and underage fees can add a significant premium to the cost.

To avoid unpleasant pricing surprises, always look for the full fee breakdown before you confirm and repeat the check when you receive the confirmation email. If the confirmation shows items you did not select, query this with your vendor immediately.

With Turo, for example, transparent pricing means you can review the full cost breakdown before you confirm — no hidden airport surcharges or unexpected charges at pickup. When renting or car-sharing, always double-check your total price in the confirmation email and make sure you understand any optional extras, such as trip protection or delivery fees.

Skipping the fuel plan fine print

Fuel is a pain point in all areas of motoring, and car sharing is no different. So, dig into the fine print of the fuel plan before you commit. Prepaid fuel can be a poor value if you return the car with a half full tank, but pay on return can sometimes be worse if per gallon rates at the counter are above local stations.

It’s generally a good idea to choose ‘Return full’, unless you expect to have a nearly empty tank by the time you get back. Refuel within ten miles of the return location, and keep your refuelling receipts as proof of what you paid.

If booking through a car-sharing site, such as Turo, each host sets their own fuel and mileage policies. Before booking, review what’s included and what isn’t. Most trips use a “return full” fuel policy — refill the tank to the level noted at check-in and upload your receipt if requested. If your trip involves long distances, look for listings with generous or unlimited mileage to avoid overage charges.

Not checking insurance coverage before the trip

Insurance confusion is one of the biggest sources of stress in traditional car rentals. You’re likely to hear a lot of insurance jargon from rental and carshare vendors, such as loss damage waiver, liability, personal accident and personal effects, and if you’re not familiar with the lingo, this can be confusing. Some travelers either brush off all of the insurance talk, or lean in too hard and overbuy. On Turo, you can choose from several protection plans that clearly outline coverage for damage and liability.

Before your trip, decide what level of protection suits you best — or confirm that your personal auto policy or credit card already provides coverage for peer-to-peer car sharing or car rental.

If you are not already covered, consider buying a collision damage waiver at the counter, or a third party policy in advance. If you are covered and want to avoid the insurance conversation altogether, simply bring proof of coverage with you to the pickup point.

Overlooking the security deposit and payment rules

Some vendors require a major credit card and will not accept debit at pickup. Others accept debit but require a higher hold, a recent utility bill, or proof of return travel. International renters may face different rules, depending on if they’re using a domestic or foreign bank/card while in the USA. It sounds simple, but a lot of rental plans are derailed simply by confusion about deposits and payments. Skip this pitfall by reading the payment policy in advance. Bring the same card you used to book, a backup card, and government issued ID that matches your reservation name.

When it comes to car-sharing, payment methods are simple, but you’ll still need to make sure your payment card and ID match your account name. Some hosts may require identity verification before handing over keys, so complete any verification steps in advance to avoid delays at pickup.

Forgetting to add additional drivers

Typically, only named drivers are covered for driving a rental car. If you’re planning a road trip with shared driving, you need to put everyone who’s going to be taking a shift behind the wheel on the paperwork or ensure they’re added on the reservation through the car-sharing platform that you’re using. This ensures that everyone is properly covered under the selected protection plan. Make sure to bring IDs that match the names on the reservation, and keep the paperwork in the glove box.

Picking the wrong vehicle

Larger vehicles can seem tempting when you’re scrolling through listings, but they’re less appealing when shelling out a fortune on fuel and you can’t find a big enough parking space within miles of your hotel. On the flip side, a small sedan can seem like a great idea for zipping around on sunny days, but in the event it can be a bad fit for a family with luggage and a child seat. It’s surprisingly common for renters to be seduced by glossy carshare or rental listings, and end up with a vehicle that’s totally unsuitable for their needs.

When you’re planning your rental car journey, pay close attention to your needs and match the vehicle to the trip. For city parking choose a compact crossover or small sedan. For long interstate drives pick a midsize sedan or a crossover with good fuel economy and seat support. For snow or mountain routes look for all wheel drive and winter ready tires.

Returning late without planning for grace periods

Most rental and carshare vendors will allow a brief grace period. After that, late returns can trigger hourly charges or an extra day. Traffic, airport security lines, and flight delays make this a common problem. So, do your very best to get back on time (or within the grace period). If you’re struck by delays, call or message ahead and let the vendor know your new ETA. As well as being courteous, this could also result in a grace period extension.

Skipping the inspection

Travelers who are rushed often sign and drive without documenting the condition of the car. That puts you at risk of a dispute about damage that you did not cause. The same problem applies at return.

Avoid being charged for damage or mess that you didn’t cause by walking around the car at pickup and documenting everything you can. Photograph or film the roof, the interior, the sides, the windshield, the bumpers and (as far as you can) the tires. Keep the images for at least 60 days to bring out as evidence if you’re asked to pay for something you don’t feel is justified. Some car sharing platforms allow you to upload photos directly through the Turo app for easy reference.

Before driving off, take a few minutes to photograph the car from all angles, inside and out. This protects both you and the host by documenting the car’s condition. Do the same when returning the vehicle, and upload photos directly through the Turo app for easy reference.

Forgetting about age rules and international license needs

Driving rules are not the same everywhere, and rental rules may vary according to perceived driver risk. For example, drivers under twenty five or over seventy may face a daily surcharge. International visitors may need a passport and in some cases an international driving permit in addition to a home country license.

So, check your vendor’s policy for things like minimum and maximum age restrictions. If you are visiting from abroad, check that your licence is valid in the state you’re visiting and for the rental company you’re hiring from. If it isn’t, apply for an international driving permit.

Leaving personal items behind

This is one of the simplest and most common issues people experience with rental cars. It’s all too easy to simply drop your stuff on the back seat and forget about it. Phone chargers, sunglasses, toll transponders, house keys, and passports are common forgotten items. While most rental vendors will have lost and found policies, it can be complicated to retrieve your stuff after the fact – especially if you’ve flown out of state since returning your rental car.

So, give yourself a final sweep checklist. Go through the center console, door pockets, the glove box, the seats, under the seats, and the trunk. Take a photo of the empty interior, and check your own bags to make sure that all essential items have been retrieved and packed.

Get a great rental car experience with a few simple strategies

A little preparation goes a long way in avoiding car rental and car sharing challenges. Reserve early, compare the full price, know your insurance, and document the car at pickup and return. Understand payment rules and bring backup IDs and cards. Match the vehicle to the trip, rather than choosing by impulse and keep receipts for fuel and tolls. Finally, recheck policy details for mileage, additional drivers, and anything else that you might need to know.

If you remember only three things, make them these. Book early with a flexible rate. Bring proof of coverage and the card you used to reserve. Photograph the vehicle at pickup and at return. Do those three and you will avoid most of the expensive mistakes that can turn a simple car hire into a headache.
