The big number in almost every state is 0.08 percent BAC, which is the legal limit that determines whether you are intoxicated (Utah is the exception because it recently lowered its limit to 0.05 percent). However, there is more to BAC levels in Texas law than a simple 0.08 cut-off point. You can still be charged with DWI when your BAC is below the legal limit, and the level of the charge can increase depending on how much your BAC exceeds the limit.
