Yes, you can absolutely use a rental car for interstate travel. This is a standard and permitted use of a rental vehicle across all major companies like Enterprise, Hertz, and Avis. However, your rental agreement will include specific rules you must follow, primarily concerning where you can take the car and any mileage limitations. The core of your planning should focus on understanding these specific terms to avoid unexpected fees.
The most critical rule to check is the "Mileage Policy." Many rental contracts include unlimited mileage for interstate travel within the contiguous United States, but this is not universal. Some cheaper rates or specific car classes may have a daily mileage cap, and exceeding it incurs significant per-mile charges. Always confirm this before booking.
Another key restriction involves "Geographical Boundaries." While driving between states is allowed, taking the rental car into Mexico or Canada often requires prior authorization from the rental company and may involve additional fees and insurance. Furthermore, some rental agreements prohibit driving on certain types of unpaved or rough roads, which could impact routes through national parks or remote areas.
One-Way Rentals are a convenient option for interstate trips where you don't plan to return to your starting point. This service allows you to pick up a car in one city and drop it off in another. However, it almost always incurs a "drop fee" or "one-way fee," which can range from a modest charge to several hundred dollars depending on the distance and demand. It's essential to get a quote that includes this fee upfront.
Finally, your personal auto insurance or the credit card you use for the rental may already provide coverage for rental cars. Before accepting the rental company's additional insurance offers, check with your insurer and credit card benefits to understand your existing coverage, which can save you money on your trip.
