Mileage policy
A different drop-off rental can involve more driving than a local round trip. Before choosing a car, review whether the offer shows unlimited mileage, mileage limits, one-way terms, and rental conditions that fit your route.
Compare one-way rentals →A one-way rental often exists because the traveler is covering distance. A short airport pickup may not make mileage terms feel urgent, but a different drop-off route can include highways, detours, overnight stops, or extra local driving before return.
Mileage terms can vary by offer, supplier, location, route, country, and car class. Treat the mileage line as part of the route setup, not as a detail to check after payment.
Unlimited mileage generally means the rental offer does not set a standard per-mile driving cap for the included rental period. The exact conditions may still depend on the supplier, rental location, country, one-way approval, cross-border rules, vehicle class, and booking terms.
Look for whether the offer shows unlimited mileage or a daily or total mileage allowance.
Check whether one-way, cross-region, or cross-border driving changes the terms for the car you select.
Vans, large SUVs, specialty cars, and premium categories may have tighter conditions than standard cars.
Mileage limits may matter more when the route is long, the itinerary is uncertain, you plan multiple stops, you expect detours, or the rental spans several days with heavy driving.
The lowest headline price may not be the best fit for every one-way route. A slightly different offer may have mileage, pickup, fuel, or return conditions that better match the trip.
Start with routes where distance, extra stops, or return timing make mileage terms easier to overlook.

How we source this: each row links to the rental company's own published one-way / drop-off policy, with the month we last checked it. These policies change often and vary by route, location and vehicle class, so treat them as a guide and always confirm the current one-way fee and terms with your supplier before you book.
Use route pages for airport return facilities, toll notes, and drive-specific issues.
Some one-way rental offers may show unlimited mileage, while others may include mileage limits or conditions. Review the rental conditions for the exact offer before booking.
It generally means the offer does not set a standard per-mile driving cap for the included rental period, but supplier rules, location rules, vehicle class, one-way terms, and cross-border conditions can still apply.
A mileage limit may matter more on longer one-way routes, uncertain itineraries, multi-stop trips, detours, cross-region drives, or weekly rentals with heavy driving.
