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

If you have a specific vehicle in mind, opt for rentals that guarantee your chosen car type. This ensures that you receive the vehicle you expect, rather than being offered an alternative.

If you're traveling with pets, verify the rental company's pet policies beforehand. While some allow pets, there might be specific fees or limitations.

Ensure your rental agreement, ID, and insurance details are easily accessible throughout your rental period for quick access if needed.

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.

Ensure you know whether your rental includes roadside assistance. This can be vital in case of breakdowns or emergencies during your rental period.

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