How old do you have to be to rent a car in Knox County?

What do you need to rent a car in Knox County?
Your driver’s license and a credit card in the same name are necessities. Don’t want to take out the company’s insurance plan? Then there’s a good chance you’ll also need proof of your own coverage.

Where can I find a Knox County car rental if I am younger than 25?
You’ll need to look up the age policy of the Knox County rental providers you’re interested in. If you’re under 25 years of age, some will charge additional fees. It’s handy to know about this ahead of time so you can have the funds ready. Every rental car company has its own rules for younger drivers, so it pays to do your research.
