Hungary vs Japan: Driving Rules Compared

Hungary tolerates zero blood alcohol behind the wheel, stricter even than Japan’s already low 0.03 limit. The road itself flips too: Hungary drives on the right, Japan on the left, a bigger daily adjustment than the alcohol gap. Motorways diverge as well, running up to 130 km/h in Hungary against a 100 km/h standard in Japan.

Hungary drives on the right while Japan drives on the left. This is one of the most significant adjustments drivers must make when travelling between these two countries. Take extra care at junctions, roundabouts, and when overtaking.
