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

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

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

When booking, check if the rental company offers extras such as GPS or child seats. These can enhance your driving experience but may incur additional costs, so it's wise to factor them into your budget.

Before renting a car, check if your personal car insurance covers rental losses. Many personal auto insurance policies and credit cards offer coverage for rentals, which could save you from extra insurance fees.

Select a pickup spot that is easy for you to reach. Many rental companies offer locations within airports for quick access, while others may require a shuttle.
