<human>:  Can you explain how to take a rental car across country boundaries?
<bot>: Taking a rental car across country boundaries is allowed in some instances, but you should exercise caution and do extensive research prior to making travel plans. It's important to be aware of the regulations of each country you plan to visit, as there may be restrictions on visitors taking rental cars across borders. Generally, it is necessary to book a car in advance and supply your travel route and passport details. When taking a rental car abroad, you will also likely be required to pay a deposit and additional fees, such as border crossing fees. You may need to purchase additional insurance or a special permit, while some countries may require that you keep a fund with them. Lastly, be sure to read the rental car company's policies and terms carefully, as some restrictions may still apply.
