Choosing the Right Car for the Distance
For road trips over 500 miles, comfort matters more than cost. Upgrading from an economy to a midsize car adds maybe $40-60 for the week but saves your back, gives you room for luggage, and improves highway stability. For mountain roads or unpaved areas, consider an SUV with higher ground clearance.
Mileage Limits
Most major US rental companies offer unlimited mileage. But watch out for smaller companies, truck rentals, and some luxury vehicle bookings — they may cap you at 100-150 miles/day with overage charges of $0.25-0.50 per mile. On a 2,000-mile road trip, that is $250-500 in overages. Confirm unlimited mileage before booking.
One-Way vs Round-Trip
If your road trip ends in a different city, compare the one-way rental fee against driving back. Sometimes the one-way fee is reasonable ($50-100). Sometimes it is absurd ($300+). You can also fly back and do a round-trip rental from your starting city, which is occasionally cheaper than the one-way fee.
Breakdown and Emergency Coverage
Verify that your rental includes roadside assistance — most do, but the response time varies. Save the roadside number in your phone before you leave. For remote road trips (desert Southwest, rural Alaska, Montana highways), also download offline maps and carry a basic emergency kit: water, phone charger, flashlight, and a blanket.
