What should you have on hand when driving a rented vehicle?

Having proper insurance for the vehicle is essential when driving a rented vehicle, especially under the terms of the Japanese Status of Forces Agreement (SOFA). Vehicle insurance protects you in case of an accident, offering financial coverage for damages and medical expenses. When renting a vehicle, it's crucial to ensure that you comply with local laws and the rental company's policies regarding coverage. Without adequate insurance, you could be liable for significant costs resulting from an incident while driving the rented vehicle.

Other options, while they may have some relevance in different contexts, do not provide the fundamental protection and legal requirements associated with operating a vehicle. For instance, having a driver's license from any country might not be sufficient unless it's an internationally recognized license that complies with local regulations. Proof of residency is typically not a requirement for driving a rented vehicle but may influence the rental process or insurance details. Additionally, relying on a friend’s documentation for verification does not establish the necessary legal or insurance status required when driving a rented vehicle. Thus, ensuring you have proper insurance is the most crucial aspect when undertaking this responsibility.
