If you have provided a sample of your breath or blood and your BAC is over 0.08, then your drivers license will be revoked for:
9 months for first violation;
1 year for second violation;
2 years for third or subsequent violation.
You will be able to apply for a reinstatement after 30 days. However, you will need an ignition interlock for the remaining 8 months (2 years if you were 0.17 or above).
On your second offense, the license revocation is one year, and the ignition interlock will be required for two years after the reinstatement.
On a third or subsequent offense, the revocation is two-years.
