Taiwan: 0.05% (BrAC 0.25 mg/L). Over 0.05% but under 0.11%: TWD 15,000 to 90,000 fine.[ citation needed ] 0.11% and above: license suspension for one year, and charge of offenses against public safety with possible prison sentence up to two years as the maximum penalty. If the driver is convicted of causing accidents, the penalty shall be increased by half.[ citation needed ] If the driver causes serious injuries or death, the license will be suspended for life or even face the death penalty.
Given BrAC 0.25 mg/L equates to 0.05%, or about 0.01% for every 0.05mg/L
It would seem @Andrei was provided the legal limit for BrAC and provided his level of BrAC. From wiki it states the most severe penalty is being >0.11%
What was Andrei’s %. given he was told his BrAC was 0.87? It would appear to be about 0.174%
