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.

Before departing, check the interior of the rental car for cleanliness and any functional issues. Ensure equipment like the radio and air conditioning works properly.

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 leaving the rental lot, inspect the vehicle for any pre-existing damage and ensure it’s recorded. Taking photos can help avoid disputes upon return.

If you plan to drive off-road, confirm with the rental agency whether it's permitted. Not all vehicles are suited for off-road conditions.

Most car rental companies will ask for a credit card deposit, which is usually held temporarily. Inquire about the specific deposit amount and the process for releasing it once the rental is complete.

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

Ask the rental agency about any specific local driving challenges or conditions. This can help you prepare for potential difficulties during your journey.
