Car rentals are services that allow individuals to hire vehicles for a short period, typically ranging from a few hours to several weeks. Customers can choose from various types of vehicles, including economy cars, SUVs, and luxury models, depending on their needs and budget. Rental companies often require a valid driver's license and a credit card for the transaction. These services are popular for travel, business trips, and special occasions, providing flexibility and convenience. Major car rental companies, such as Enterprise, Hertz, and Avis, operate in airports and city locations, making it easy for customers to access vehicles when needed.
