How old do you have to be to rent a car?
<|assistant|>
In the United States, the minimum age to rent a car varies depending on the company, but you typically need to be 21 years old or older. Some companies will rent to 18-year-old drivers with a valid learner's permit, but an adult (over 25) usually must sign the rental contract. Additionally, you will likely need to have had a driver's license for at least 1-2 years and have a good driving record.
