What document is recommended for operating a POV across international borders?

An International Driver's Permit (IDP) is recommended for operating a Privately Owned Vehicle (POV) across international borders because it serves as a translation of the driver's existing driver's license and can be recognized by foreign authorities. The IDP is essential for ensuring that drivers can easily communicate their driving qualifications in various languages, which is particularly important in countries where English may not be widely understood.

Having an IDP can help mitigate potential issues or misunderstandings with law enforcement or rental agencies, as it is an internationally accepted document that proves an individual’s right to drive in another country. While other documents like vehicle registration and local insurance policies are important for operating a vehicle, they do not suffice as proof of a valid driving license in a foreign country. Similarly, a passport is essential for identification purposes and border crossings, but it does not hold any information regarding a person's driving capabilities. Thus, the IDP is the most relevant and recommended document for driving internationally.
