The maximum suspension for a first conviction of DUI (driving under the influence) varies by state. In some states, the maximum suspension can be up to one year, while in others it may be as little as 30 days. The length of the suspension may also depend on the circumstances of the offense, such as the driver’s blood alcohol content (BAC) at the time of arrest. It is important to check the specific laws and penalties for DUI in your state.
