Croatia had 0 blood alcohol for a few years if I remember correctly, it was deemed not successful after statistic didn't show a reduction in accidents and fatalities, although I believe it was probably reversed back to 0.5 per mille because of lobbying and tourism. We also had horsepower limits for young drivers, but that was deemed unconstitutional. I think they're now considering a trial driver's license for young drivers, might be an eu thing, I'm not sure about the details.
