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.

Some companies may provide a complimentary tank of fuel with your rental. Understand the conditions, such as how much fuel you need to return with to avoid fees.

Most rental companies will require a credit card for the deposit, which is typically frozen in your account. Make sure to inquire about the specific deposit amount and the policy for releasing the freeze.

Before leaving the rental lot, check if the vehicle has essential emergency supplies, such as a spare tire, jack, and first aid kit.

If you plan to share driving, check if the rental company allows a second driver and whether there are additional fees. Some companies offer free second driver options under certain conditions.

Before booking, check for any promotional offers or discounts that may be available. Many rental companies provide seasonal deals or discounts for early bookings.

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