7. 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.

8. Learn key phrases. If you do not speak the local language, learn basic driving-related phrases. In an emergency, being able to communicate with police or paramedics can be invaluable.
