When renting a car, understand the fuel policy. A 'Full-to-Full' policy means you return the car with a full tank, while 'Same-to-Same' means you return it with the same level of fuel. Full-to-Full is often more cost-effective.

Before returning the vehicle, clarify the return procedures with the rental company. Knowing where to drop off the car and any required inspections can streamline the process.

Many rental firms prefer credit cards and may not accept debit cards for payment. If you're using a debit card, confirm the company's policies before making a reservation.

Before renting a car, check if your personal car insurance covers rental losses. Many personal auto insurance policies and credit cards offer coverage for rentals, which could save you from extra insurance fees.

Make sure you know the details of the roadside assistance included with your rental. This is crucial in case of breakdowns or accidents.

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher rates.

Note that some rental companies impose age restrictions or additional fees for drivers under 25. Always verify the age policy when booking.

Research any toll roads on your travel route and understand the payment options. Some rental companies provide toll transponders for convenience.
