Croatia vs Japan: Driving Rules Compared

Croatia replaced its flat minor-speeding fine with a tiered scale from 1 Jul 2026 — EUR 30 for under 10 km/h over inside a settlement, rising from there. Layer that onto the fact that Japan drives on the left while Croatia keeps right, and the motorway gap of 130 km/h versus 100, and this is a pairing with more than one adjustment to make. Penalties, tyre rules and kit are compared in full below.

Switching between Croatia (right-hand traffic) and Japan (left-hand traffic) requires significant adjustment. Pay special attention to turning, roundabouts, and overtaking — these are the situations where drivers most commonly make errors after switching sides.

Practical Tips for Driving in Both Countries

If you are planning to drive in both Croatia and Japan, here are some practical tips to keep in mind:

1. Research before you go. Familiarise yourself with the specific rules of each country before your trip. Print or save a summary of key rules for quick reference.

2. 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.

4. Watch for different road signs. While European countries share many sign conventions, there are country-specific signs you should recognise. Review a local driving guide before your trip.

5. 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.

6. 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.

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. 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.
