Brazil vs Portugal: Driving Rules Compared
Data verified:
1 min readBrazil’s Lei Seca has enforced zero blood alcohol since 2012 — order a single beer before driving and you are already over the limit, a rule Portugal does not share at its 0.05 threshold. Motorways add another 10 km/h to the gap, running to 120 km/h in Portugal against 110 km/h in Brazil. Both countries keep traffic on the right, so at least the steering side needs no adjustment.
