Yes, you can legally rent a car at 19 in Missouri, but it is significantly more challenging and expensive than for drivers 25 and older. Missouri state law does not set a minimum rental age, leaving the decision to individual rental companies. Most major national companies like Enterprise, Hertz, and Avis set their minimum age at 21. However, a key exception is Enterprise Holdings—which includes Enterprise, Alamo, and National—which allows 18- to 20-year-olds to rent at many of their Missouri locations. The major hurdles you will face are a Young Renter Fee (often $20-$30 per day) and a limited selection of vehicle classes, typically excluding premium cars, SUVs, and minivans.
Finding a rental requires direct contact with specific locations, as policies can vary even within the same city. You must also meet all other standard requirements: a valid driver's license held for at least a year, a major card in your name (debit cards are rarely accepted for young renters), and proof of insurance. Your own auto insurance policy may provide coverage, but you must verify this beforehand. Renting from an off-airport location can sometimes be easier and may have slightly lower fees.
Here is a comparison of policies from major companies that may rent to 19-year-olds in Missouri:
| Rental Company | Minimum Age in Missouri | Young Renter Fee (Approximate) | Vehicle Class Restrictions | Key Requirements |
|---|---|---|---|---|
| Enterprise Holdings | 18 | $20 - $30 / day | Typically compact to full-size cars only | Credit card, license held for 1+ year |
| Local/Regional Companies | 18 or 19 | Varies by company | Varies | May accept debit cards; call to confirm |
| Hertz | 20 (at select locations) | Varies | Significant restrictions | Credit card, specific location approval needed |
| Budget | 21 (standard policy) | Not applicable for under 21 | N/A | Standard minimum age is 21 |
The most reliable strategy is to call several Enterprise locations directly. Be prepared for the additional daily cost, and always read the rental agreement thoroughly to understand all fees and restrictions before signing.

It's a total pain, but yeah, it's possible. I just went through this last month trying to get a car for a road trip. Your only real shot is with Enterprise or maybe a local spot. Expect to pay an extra fee every single day on top of the rental cost, and they'll basically only rent you the most basic car they have. Forget about a cool SUV. Your biggest hurdle will be the card—it has to be in your name, no exceptions. Start calling places way in advance.

Focus on the financials. While legally permissible, the economics are unfavorable. The mandatory Young Renter Fee can effectively double the advertised daily rate. Furthermore, your options are limited. Using a debit card is typically not an option, and relying on your personal insurance policy requires explicit confirmation of rental coverage. For a 19-year-old, the total cost often outweighs the convenience. Exploring alternatives like ride-sharing or public transport for short trips may be more financially prudent.

As a parent who helped my son navigate this, here's my advice. Enterprise is your best bet. Call the specific branch, don't just book online. The extra fee is a hassle, but it's non-negotiable. The most important thing is . Call your own auto insurance provider first to confirm you're covered for rental cars. This can save you from buying expensive coverage at the counter. Also, make sure the young driver has had their license for a full year—that’s a firm rule. It’s doable with careful planning.

Look beyond the big names at the airport. Smaller, locally-owned rental companies near universities or in smaller towns are sometimes more flexible with their policies for young drivers. They might have lower fees or be more willing to work with you. Always have your license, a major card with enough available credit for the security hold, and proof of insurance ready. The process requires patience and several phone calls, but securing a vehicle is achievable if you target the right companies and meet all their criteria without exception.
