Planning a trip? Whether you’re renting a car for a cross-country move, an international vacation, or a weekend getaway that ends in a different city, understanding your rental car company’s policies is essential.
Rental car terms can vary widely depending on the provider, location, and type of trip you’re taking. To help you avoid unexpected fees, restrictions, or surprises, here’s a breakdown of the most important rental policies to know in 2025—including one-way rentals, cross-border restrictions, and mileage limits.
What Is a One-Way Rental?
A one-way rental allows you to pick up a car at one location and return it to another. This is perfect for:
- Road trips that don’t circle back to your starting point
- Moving to a new city
- Flying into one airport and out of another
Things to keep in mind:
- One-way rentals often come with a drop-off fee, especially for long distances.
- Availability may be limited depending on the route and car type.
- Booking early helps ensure the best price and selection.
Tip: Use comparison tools like AutoRentals.com to find providers with low or no drop-off fees.
Renting a Car for Cross-Border Travel
Crossing a national border in a rental car—such as from the U.S. into Canada or Mexico—requires special permission.
U.S. to Canada:
- Most major rental companies allow travel across the border into Canada.
- You must inform the rental company in advance.
- Proof of insurance is often required.
U.S. to Mexico:
- Fewer rental companies allow cross-border travel into Mexico.
- You will likely need to purchase additional Mexican auto insurance.
- Not all car types may be eligible.
Tip: Always ask about cross-border policies when booking. Failure to disclose your travel plans may void your rental agreement or insurance.

Mileage Limits & Unlimited Mileage
Some rentals come with unlimited mileage, while others cap the number of miles you can drive without incurring extra fees.
- Unlimited mileage is common for standard rentals within the same region or state.
- Mileage caps may apply for specialty vehicles or discounted rates.
Tip: Estimate your travel distance in advance and ask about mileage caps before booking.
Other Rental Policy Considerations
- Underage Driver Fees: Renters under 25 may face additional charges.
- Additional Drivers: Must be listed on the agreement; fees may apply.
- Fuel Policies: Full-to-full is most common—return the car with a full tank to avoid extra fees.
- International Travel: Rental requirements and insurance coverage vary by country. Always verify what’s required if you’re renting abroad.
Conclusion
Being informed about your rental car company’s policies can help you save money, avoid complications, and have a smoother travel experience. Whether you’re planning a one-way road trip, heading over the border, or simply trying to avoid mileage overage charges, clarity is key.
