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.

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

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

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.

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

Before booking, review the rental agreement for any hidden fees such as airport surcharges, additional driver fees, or late return penalties. Understanding these can help you budget more effectively.
