To rent a car, you generally need a valid driver's license, identification (passport or driver's license), and a credit card. Most rental companies require a minimum age of 21, but higher age limits may apply for certain categories (e.g., luxury cars, larger SUVs). A deposit is usually required at the time of booking and pickup, the amount of which depends on the rental company and the chosen insurance package. Credit card is an accepted payment method, but some locations also accept cash.
It’s important to review the insurance options. CDW (Collision Damage Waiver) covers damage to the car, while Theft Protection covers losses from theft or burglary. Excess Reduction (or Super CDW) reduces the amount of the deductible. It’s worth asking the rental company if your own insurance coverage extends to the United States, so you can avoid unnecessary costs.
