In Utah, effective December 30, 2018, an adult driver can be charged with driving under the influence (DUI) if his or her blood alcohol concentration is ______ or higher.

Explanation

Until 2018, the legal limit for adult blood alcohol concentration (BAC) in all US states was under 0.08%. However, effective December 30, 2018, the legal limit in Utah is reduced to under 0.05%. That is, if your BAC is 0.05% or higher, you can be charged with driving under the influence (DUI). Note that the 2017?2018 edition of the Utah Driver Handbook has not yet been updated to include this change.
