The legal limit is 0.08% BAC for drivers 21+ in all 50 states. For commercial drivers, the limit is 0.04%. For drivers under 21, all states have zero tolerance laws (0.00-0.02% BAC).

How long is license suspension for a first DUI?

It varies: California 4-6 months (DMV) / 6 months (court), New York 6 months, Texas 90 days-1 year, Florida 6-12 months, Washington 90 days. You may be eligible for a restricted license with an ignition interlock device.

Will a first DUI offense show up on a background check?

Yes. A DUI conviction is a criminal offense that appears on background checks. It can affect employment opportunities, especially for jobs requiring driving. Some states allow expungement after completing probation and meeting other requirements.

Can I get a DUI reduced to a lesser charge?

In some cases, prosecutors may reduce a DUI to 'wet reckless' (reckless driving involving alcohol) or 'dry reckless' through plea bargaining. This is more likely for first offenders with BAC marginally above 0.08% and no aggravating factors.
