Final answer:
In the US, a BAC of .08 or higher, or refusal to take a breath test, typically results in a 90-day license suspension for a first offense, though this can vary by state.
Step-by-step explanation:
In the United States, if you refuse to take a breath test or are found to have a blood alcohol concentration (BAC) of .08 or higher while driving, and it is your first offense, the general consequence is a mandatory license suspension. The duration of the suspension can vary by state, but a common period for a first offense is 90 days.
It is important to note that each state may have different laws and penalties, and severe penalties can apply to those operating a vehicle under the influence of alcohol. If you refuse to take a breath test or your blood alcohol level is .08 or higher while you are driving, and it is your first offense, you will automatically have your license suspended for 90 days.
