Where to rent a car in Knoxville and what each location offers
Knoxville has rental desks at McGhee Tyson Airport (TYS), which is about 12 miles south of downtown, plus several off-airport locations scattered through the city. The airport location is the most convenient if you're flying in, but off-airport branches often have lower daily rates and less crowded counters. Major chains operating in Knoxville include Enterprise, Hertz, Budget, Avis, and National.
Off-airport locations cluster around downtown and near the University of Tennessee campus. These branches typically have shorter wait times than the airport counter, especially during peak travel seasons. Some are open seven days a week; others close on Sundays or have limited weekend hours. Call ahead to confirm hours before you arrive, particularly if you need an evening or weekend pickup.
A few local and regional companies also operate in Knoxville, though they have fewer locations than the national chains. These smaller operators sometimes offer competitive rates for longer rentals or specialty vehicles, but availability can be limited and they may not have 24-hour roadside information networks.
Key Takeaways
- McGhee Tyson Airport has rental desks from major chains, but off-airport locations in downtown Knoxville and near UT often have lower rates and shorter lines.
- You will need a valid driver's license, a credit card in your name, and proof of insurance before you can pick up a rental car.
- Damage waivers and additional insurance offered at the counter are often redundant if your personal auto policy or credit card already covers rentals.
- One-way rentals from Knoxville to other cities are possible but carry a drop-off fee that varies by destination and company.
- Booking online typically locks in a lower rate than walking up to the counter, and you can often modify or cancel free of charge up to 24 hours before pickup.
Documents and payment you need at pickup
When you arrive to pick up your rental, bring your valid driver's license, a credit card in your own name, and proof of insurance. The rental company will run your license through their system and may check your driving record. If your license is expired or suspended, or if you have recent at-fault accidents or serious violations on your record, the company may refuse to rent to you or charge a higher daily rate.
The credit card must be in your name — rental companies will not accept a card belonging to someone else, even if that person is present. They use the card to place a hold for the rental cost plus a damage deposit, which is typically $200 to $500 depending on the vehicle class. This hold is not a charge; it releases when you return the car undamaged. If you pay with cash or debit, most companies require a larger deposit and may not rent to you at all.
Proof of insurance can be your personal auto policy, your employer's fleet policy, or a credit card's rental car coverage. Bring the actual document or a digital copy on your phone. The rental company will note your coverage details in their system. If you have no insurance, you can purchase a damage waiver from the rental company, though this is usually more expensive than adding a few dollars to your daily rate.
Understanding damage waivers and insurance at the counter
When you sign the rental agreement, the agent will offer you a damage waiver (also called a Loss Damage Waiver or LDW) and sometimes additional liability coverage. The damage waiver means the rental company will not charge you for dents, scratches, or collision damage to the car. Without it, you are responsible for any damage, up to the full value of the vehicle.
Before you buy this coverage at the counter, check what your personal auto insurance and credit card already cover. Most personal auto policies extend to rental cars, and many premium credit cards include rental car damage coverage automatically. If your coverage is already in place, paying for the rental company's waiver is redundant. Call your insurance company or credit card issuer before your trip to confirm what is covered and what the deductible is.
If you have no personal insurance and your credit card does not cover rentals, the damage waiver is worth buying. The daily cost is usually $15 to $25, depending on the vehicle. Read the fine print: most waivers exclude damage from off-road driving, racing, or gross negligence, and some exclude damage to the windshield or undercarriage.
Booking online versus walking up to the counter
Booking online through the rental company's website or a travel site like Kayak or Autoslash almost always results in a lower rate than the walk-up counter price. Online rates are locked in at the time of booking, so you know exactly what you will pay before you arrive. Walk-up rates fluctuate based on current demand and inventory, and they are almost always higher than pre-booked rates.
Most online bookings allow you to modify your reservation or cancel free of charge up to 24 hours before your scheduled pickup time. After that window closes, changes or cancellations may trigger a fee. Read the terms before you book: some discount sites impose stricter cancellation policies than the rental company's own website.
If you book through a third-party site like Kayak or Autoslash, you will still pick up the car at the rental company's location and sign the agreement with them. The third-party site is only a booking engine; it does not change your rights or obligations. The rental company's cancellation and modification policies explore, not the third-party site's.
One-way rentals and drop-off fees
You can rent a car in Knoxville and return it to a different city, but the rental company will charge a one-way or drop-off fee. This fee varies widely depending on the destination and the company. A one-way rental from Knoxville to Nashville might cost $40 to $80, while a drop-off in Atlanta could run $100 to $150 or more. Some companies waive the fee if you book a longer rental or rent a larger vehicle.
One-way fees are not always transparent in online quotes. When you search for a one-way rental, the price shown may or may not include the drop-off fee — read the fine print or call the company to confirm. Comparing one-way rates across companies is important, because fees vary significantly even for the same route.
If you are returning the car to an airport location rather than a city branch, the fee may be higher. Some companies charge extra for airport returns because they have to move the vehicle to a lot outside the terminal area.
Age restrictions and young driver surcharges
Most rental companies in Knoxville require you to be at least 21 years old to rent a car. Drivers under 25 typically pay a young driver surcharge, which ranges from $15 to $30 per day depending on the company and the vehicle class. Some companies do not rent to drivers under 25 at all, particularly for premium or sports vehicles.
If you are between 18 and 20, only a few companies will rent to you, and they usually require a higher damage deposit and charge significantly more per day. Call ahead to confirm age policies before you book, because availability for young drivers is limited and rates are not always shown online.
Drivers over 75 may also face restrictions or surcharges, though these policies vary by company. Ask when you book if you fall into this age range.
Fuel, mileage, and return policies
Most rental cars in Knoxville are rented on a full-to-full fuel basis: you pick up the car with a full tank and return it with a full tank. If you return it with less fuel, the company will charge you for a fill-up at their pump, which is typically more expensive than gas station prices. Some companies offer a pre-purchase fuel option, where you pay for a full tank upfront at a set price; if you return the car with fuel remaining, you do not get a refund.
Mileage is usually unlimited on daily rentals, but some companies impose mileage limits on weekly or monthly rentals. Read your agreement to confirm. If you exceed the limit, you will be charged per mile, typically 15 to 25 cents per mile.
Return the car by the time specified in your agreement. Late returns are charged at the daily rate or a higher hourly rate, depending on how late you are. Some companies allow a grace period of 30 minutes to an hour; others charge when ready. Confirm the grace period when you pick up the car.
What to inspect before you drive away
Before you leave the rental lot, walk around the car with the agent and point out any existing damage — dents, scratches, stains, or mechanical issues. The agent should note these on the rental agreement or take photos. This protects you from being charged for damage you did not cause. Do not skip this step, even if it takes a few extra minutes.
Test the brakes, lights, windshield wipers, and air conditioning. Check that the spare tire and jack are in the trunk. Confirm the fuel gauge reads full. If anything is not working or the car feels unsafe, ask for a different vehicle before you sign the agreement. Once you sign, you are responsible for the car's condition.
Take photos of the car's exterior and interior on your phone before you drive away. These photos are your record if a dispute arises later about damage or missing items.
Frequently Asked Questions
Can I rent a car in Knoxville if I have a suspended license or recent DUI?
No. Rental companies run your driving record and will refuse to rent to you if your license is suspended or revoked. A recent DUI conviction will also disqualify you or result in a much higher rate. You must have a valid, unrestricted driver's license to rent.
What happens if I get into an accident with a rental car?
Call the rental company when ready and report the accident, even if it is minor. Do not leave the scene. Get the other driver's information and take photos. The rental company will file a claim with their insurance or your coverage, depending on your agreement. You may be liable for the deductible if you did not purchase their damage waiver and your personal insurance does not cover it.
Can I rent a car if I do not have a credit card?
Most companies require a credit card in your name for the damage deposit hold. A few will accept a debit card, but they typically require a larger deposit and may refuse to rent to you. Call the rental location directly to ask about their debit card policy before you book.
Is it cheaper to rent from the airport or downtown?
Downtown and off-airport locations usually have lower daily rates than McGhee Tyson Airport, sometimes by $10 to $20 per day. However, the airport is more convenient if you are flying in. Compare rates for both locations when you book to see which makes sense for your trip.
What if I need to extend my rental after I pick up the car?
Call the rental company as soon as you know you need more time. If the car is available, they will extend your reservation and adjust your bill. If the car is already booked for another customer, they may not be able to extend. Extending by phone is usually more expensive than booking the extra days online before your trip.
