Japan vs Luxembourg: Driving Rules Compared

Swap Japan for Luxembourg and three things change together: the steering side flips from left to right, the motorway pace jumps from 100 km/h to 130, and the legal alcohol margin loosens from 0.03 g/L to 0.05. That’s a bigger adjustment than most pairings in this series, so budget extra care for the first few junctions. Tyre and equipment rules are compared in full below.

Switching between Japan (left-hand traffic) and Luxembourg (right-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.

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

2. 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. 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.

6. 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.

7. 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.
