There’s no better way to experience the vast and varied landscapes of the United States than by hitting the open road. From coastal highways and mountain passes to bustling cities and quiet countryside, a road trip allows you to explore the country at your own pace. But before you jump behind the wheel, there are a few key things to understand about renting a car in the U.S.
Whether you’re an international visitor or a domestic traveler, this guide will walk you through everything you need to know, from rental requirements to insurance options, and even how to avoid hidden costs.
Who Can Rent a Car in the U.S.?
Most rental car companies in the U.S. require drivers to be at least 21 years old. However, drivers under 25 may face a “young driver surcharge.” If you’re an international driver, make sure you have a valid driver’s license from your home country. Many agencies also require an International Driving Permit (IDP) in addition to your original license, especially if your license isn’t in English.
Be prepared to show a major credit card when you pick up your vehicle. Some rental agencies also accept debit cards, but this may come with additional restrictions or deposits.

Choosing the Right Car for Your Journey
When it comes to choosing a vehicle, think about where you’re going and how many people you’re traveling with. If you’re sticking to city roads, a compact car will be fuel-efficient and easier to park. But if you’re heading to national parks or mountainous areas, or plan to carry a lot of gear, an SUV or 4×4 might be more suitable.
Also consider the weather conditions. Renting a car in the U.S. during winter in northern states may require an all-wheel-drive vehicle or snow tires.
Understanding Rental Car Insurance in the U.S.
One of the most confusing aspects of renting a car in the U.S. is insurance. Rental agencies will usually offer several types of coverage:
- Collision Damage Waiver (CDW): Covers damage to the rental car.
- Liability Insurance: Covers damage to other people or property.
- Personal Accident Insurance: Covers medical costs in the event of an accident.
- Personal Effects Coverage: Protects your belongings inside the car.
If you have personal auto insurance, check with your provider to see if it extends to rental cars. Many credit cards also include rental car insurance if you use the card to book and pay for the rental. However, the coverage may be secondary and not include liability.

Avoiding Hidden Fees and Extra Charges
Rental car prices might look affordable at first glance, but it’s easy to rack up additional fees if you’re not careful. Here are some tips to avoid hidden costs:
- Prepaying for Fuel: It’s often cheaper to fill the tank yourself than to use the agency’s fuel service.
- Toll Fees: Consider bringing your own toll pass if you’re traveling in regions with frequent toll roads.
- Additional Driver Fees: If more than one person will be driving, check for fees and policies.
- Drop-Off Charges: Renting in one location and returning the car in another can lead to hefty fees.
- Late Returns: Even an hour over the return time could incur an extra day’s charge.
