Practical Tips for Driving in Both Countries

Before hitting the road in Japan or New Zealand, consider these practical driving tips:

1. Adjust to speed limits immediately. When crossing the border, speed limits change. Look for signs and adjust your driving accordingly. Do not rely on habits from the other country.

2. Carry the right documents. Ensure you have your driving licence, IDP (if needed), vehicle registration, and insurance documents. Some countries require you to carry these at all times.

3. Check insurance coverage. Verify that your motor insurance or rental agreement covers driving in both countries. A Green Card may be required for cross-border travel.

4. Plan fuel stops. Fuel prices and station availability can vary significantly. In some regions, stations may close at night or on Sundays.

5. Equip your vehicle properly. Ensure you have all mandatory equipment for both countries. It is better to carry extra items than to face a fine for missing equipment.

6. Use a GPS or navigation app. Modern navigation apps often include speed limit warnings, toll information, and real-time traffic updates that can help you comply with local rules.

7. Respect local driving culture. Overtaking norms, horn usage, and right-of-way conventions differ. Observe local drivers and adapt accordingly.

8. Be aware of environmental zones. Many cities have low-emission zones that restrict older vehicles. Check if you need an environmental sticker for either country.
