If sharing driving responsibilities, check the policies regarding additional drivers. Some companies charge fees for each extra driver, while others may include it for free under certain conditions.

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.

Some rental agreements come with mileage limits, while others offer unlimited mileage. Make sure to review the mileage policy to avoid unexpected fees.
