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.

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.
