Most car rental companies in Riverside require a credit card for renting a car. This is because the credit card is used for security deposit purposes and to cover any potential damages or additional charges during the rental period. If you don't have a credit card, you may need to check with individual rental companies to see if they offer any alternative payment options.

When renting a car in Riverside, you will typically need the following documents:

• A valid driver's license from your home country or an international driver's license
• A valid passport or identification card
• A credit card in the renter's name for the security deposit
• Proof of insurance if you choose to decline the rental company's insurance coverage

It's always a good idea to check with the specific rental company for their document requirements, as they may have additional requirements or variations.

The rental period for car rentals in Riverside can vary depending on the rental company and your specific needs. Most rental companies offer daily, weekly, and monthly rental options. The minimum rental period is usually 24 hours, while the maximum rental period can be several weeks or months. It's best to check with the rental company for their specific rental period options and rates.

Yes, it is possible to rent a car in Riverside if you are under 25 years old. However, many car rental companies may charge an additional fee for drivers under the age of 25, known as a "young driver fee" or "age differential fee." This fee is applied to cover the increased insurance risk associated with younger drivers. It's important to check with the rental company for their specific age requirements and any additional fees that may be applicable.

The cancellation policy for car rentals in Riverside can vary depending on the rental company. It is important to carefully read and understand the terms and conditions of your rental agreement before making a reservation. Some rental companies may offer free cancellation up to a certain time period before the pick-up time, while others may charge a cancellation fee. It's best to check with the specific rental company for their cancellation policy and any applicable fees.

Most car rental companies in Riverside offer additional insurance coverage options for renters. However, whether or not additional insurance is necessary depends on your personal insurance coverage. If you have personal car insurance or coverage through a credit card, it may provide sufficient coverage for your rental car. It's important to review your insurance policy or contact your insurance provider to understand what coverage extends to rental cars. If you do choose to decline the rental company's insurance coverage, it is advisable to have proof of your own insurance coverage in case of any accidents or damages during the rental period.
